74 Seacraft Tsunami
 

I picked up a 74 Seacraft Tsunami from a really good friend the other day. Looking forward to the restore. I am lucky as the gel coat on the outside still looks great. It has a new (2yrs) 150 gal. gas tank and a 40 gal aux. tank. A new radar/whip arch and is overall in pretty good shape after a good cleaning. It will see a New transom and deck real soon. All wiring will be stripped and all elecrontics will be replaced. I did real well on the actual boat and trailer so I am gonna go with a New 250 4-stroke suzuki as well. Been looking over the site for the last year and have learned a tons from the guys on the site.

Anyone out there with the 4-stroke / 23 Tsunami set up. I'd love some performance stats if possible.

First three are when we pulled it out.

Second two are after a 45 min wash job.

Re: 74 Seacraft Tsunami
 

Nice boat!

Re: 74 Seacraft Tsunami
 

Nice looking boat. Any idea how it runs with the 275 V8?

Re: 74 Seacraft Tsunami
 

10 steel dive tanks, 190 gal. fuel, 300lbs ice, dive gear, spearguns and 4 guys. = 27 - 28 knt cruise = 1nm per gallon. Ouch!

Top end was approx 44 to 45 mph.

Scott, your boat is similar to this one. Is it the same size? Whats powering yours and do you know of anyone with the 4-stroke Suzuki on this type boat.

Jason

Re: 74 Seacraft Tsunami
 

Yes, we have the same boat. It's got a '97 Yamaha 225 on it. Sorry, I don't know of anyone around me running a Tsunami/Sceptre with a single 4-stroke, but I'm sure the Suzuki 250 would be a great engine for this boat.

Re: 74 Seacraft Tsunami
 

I got to be honest, to me that's the best looking of all the cabin type Seacraft. I was trying to find one for my next boat. Why I need another 23 ft boat is another story.

Re: 74 Seacraft Tsunami
 

Great looking boat! It's amazing that the boat looks like it has been sitting for 5 years yet has lenco trim tabs. I wonder how the weight of the old v8 275 compares to the new 250 Suzi? As for fuel burn you can expect about 10gph at 4000rpm and you will probably turn 25-26 kts. Trever has a 250Suzi on a CC and his #'s are almost identicle to my twin 115's.

You may consider twin 115/140 suzi's because I believe your boat carries more weight forward then the CC's. Twin 140's may only be 3-4k more when all is said and done and I feel it is a worthwhile investment. Good luck with whatever you choose and welcome to the board.

Re: 74 Seacraft Tsunami
 

Very nice! You may be able to pickup a few bucks for that badazz 4.0 liter V-8 rude over at scream and fly.

Re: 74 Seacraft Tsunami
 

Forgive my ignorance.. But what is a Scream and Fly?

I was thinking about having the Rude rebuilt but its too much of a GAS HOG

Re: 74 Seacraft Tsunami
 

www.screamandfly.com

Its a website geared towards outboard engines

Re: 74 Seacraft Tsunami
 

I've heard that those V-8s had an oiling issue with the top 2 cylinders, so rebuilds were fairly common and part of the reason for discontunuing the model. Anyone else hear this?

Re: 74 Seacraft Tsunami
 

Yes, I have a friend who heard that. Went to Florida to buy a boat, had it shipped back to Maine. Splashed her, and within 20 minutes of being in the water had two cylinders busting through the cowling...good times.

Re: 74 Seacraft Tsunami
 

Briguy,
Thanks for the comments. I think that the Rude and the Suzi-250 are comparable in weight. The 275 may be heavier. I also think that they are comparable in HP as the Rude's HP was not rated at the prop. I'd like to see a 28-29kt cruise out of the 250 with burning 2 or more per nm.

Jason

Re: 74 Seacraft Tsunami
 

Please let me know what kind of performance you get with the new motor- I have the same boat and am looking to repower with a 250 suzuki 4 stroke. Nice boat-good luck

Re: 74 Seacraft Tsunami
 

Let the games begin, the money pit has opened up.

First off, trailer rehab. Gonna get rid of the old rollers and such. Going with big cypress bunks that should make putting the boat on the trailer easier. New tires, new fenders, bearings - hubs etc, and light kit. This will reflect the first hunk of change dropped into the boat after it was purchased.

Next, gutting all wiring and steering. Followed by removing that big Rude off the back and finding a home for it. Then the deck / transom removal and repair etc. Bracket, Motor.

I really enjoy the site. Anyone else donea Sceptre or Tsunami that would have some photos.

Thanks, Jason

Re: 74 Seacraft Tsunami
 

Sorry I did not see this thread earlier.

Nice boat and it looks real clean, after the wash [img]/images/graemlins/grin.gif[/img]

Thanks for sharing you pictures and I can not wait to see more. There are 2-3 comercial guys around my work running 23 SeaCrafts with 225-250 Suzuki 4-strokes. I am sorry I do not know the #'s they are getting.

Re: 74 Seacraft Tsunami
 

Jason,

I think I'm in a pretty comparable situation, about a month behind you. I bought a 73 Tsunami at the end of November. Mine has already had the transom enclosed with a 96 225 Merc on it. I'm not messing around with the motors right now but do need to do a little restoration of the cabin and windscreen/cabin door. Seems like between the two of us we'd have a near perfect complete boat. I have pics if you'd like from when I bought it which I can email you (haven't bothered to try to figure out how to post them yet, sorry). I'd love to see some more of yours. I'm sitll trying to get a good idea of how the cabin/windscreen/bow access all worked as original before it was crewed & welded shut on mine.

Re: 74 Seacraft Tsunami
 

I'll take some photos of the forward cockpit area and post them for you. It is still all intact and operable on the boat. That'll have to wait until the trailer work is complete and I have the boat at the house.

Any phots can be sent to jstanley@tbegroup.com

Re: 74 Seacraft Tsunami
 

just sent you the photos I have of mine

Re: 74 Seacraft Tsunami
 

the photos bounced back. It's a 5mb zip file. Is that too large for your mailbox?

Re: 74 Seacraft Tsunami
 

Thanks for trying, Can you split the photos into two e-mails? Thanks again. I will have photos this weekend of the forward hatch assembly.

Trailer was almost complete when I was there today.


Thanks, Jason

Re: 74 Seacraft Tsunami
 

I split it in to three. Let me know if it doesn't work.

Re: 74 Seacraft Tsunami
 

I recieved the photos. Wasn't that the boat that was for sale not long ago on the site? Very nice.

I'll try to get you some photos of the forward hatch.

Jason

Re: 74 Seacraft Tsunami
 

i just bought almost the same boat.I have an i/o and I'm going to put a pair of 135 optimax on a braetot it. I would like to know where the 150 gallon tank was installed.
Good luck

Re: 74 Seacraft Tsunami
 

1973 Tsunami,
Please see the attached photos of the forward hatch area. I tried to get a few shots at the different steps it takes to open the hatch. Hope this helps.

Re: 74 Seacraft Tsunami
 

Finally got the boat home after I had the trailer re-hab done. I would have done that myself but one of my spearfishing buddies owns R & R unlimited (Trailers) and gave me a great deal on the trailer job. Thanks Rich!

Trailer is new again, so on to better things.

I have a friend that lives in Missouri and wants to see photos start to finish of the boat. So, sorry if I post photos that don't seem to have much meaning.

All I got done today was general cleanup of the boat. The boat will be gutted, wiring, transom, deck etc. I removed all of the wood out of the forward cuddy. I'm not sure if it was all original (someone chime in and let me know) but if it was, what a mess. A wooded door frame that got wet and delaminated the dash seemed to make quite a mess. Anyway, I'll have some cutting and grinding to do and I'll replace it all with glass.

I dont see a door going back on this boat. In Florida, It would just get in the way. It all cleaned up pretty nice.

Re: 74 Seacraft Tsunami
 

I have a '75 Tsunami and if I want to get through the hatch onto the deck, I remove the hinged hatch completely and stow it below. I usually do this anyway before I even leave my boat slip. There is a ladder that is securely mounted/easily removed - it leads up to the deck for easy access.

No doubt, the companionway hatch is a pain-in-the a-s, even when in brand new condition - which mine is close to. I have not been able to think of a way of changing it and making it work any better - and have decided to deal with it - it is a necessary evil for this boat ( like the 'flooding scuppers' ). I really make use of the cabin below and specifically searched for a Potter built Tsunami for that reason.

Looks like you have yourself a nice project. Good luck.

Re: 74 Seacraft Tsunami
 

Alright now, I see how the thing works and I think I may be able to get mine back by just removing some screws on the hatch and cracking the paint on the window frame. Much easier than I'd feared...If I'm right that is. True it doesn't seem like the easiest set up but it will do for now and beats trying to reinvent the wheel.

My 73 is the one that was listed on this site right before Thanksgiving. That's actually how I found this place.

Re: 74 Seacraft Tsunami
 

If 90% of the reason to go up front is to place or reteive the anchor maybe a windlass would be the answer.

My brother has a 36 Searay and hates to go around the side of the boat if its choppy, now he just hits the switch and up and down you go.

Re: 74 Seacraft Tsunami
 

I don't fish, so I can count on one hand in 10 years that I've anchored a boat. We spearfish so there is no anchoring. The hatch seems fine to me, if I had to get up there, it would provide ample access. The deck space and amount of weight the boat is capable of handleing is why I chose this particular boat.

I've read about usung Coosa Board for decks and transoms on this site. I just got a quote for 191.00 a sheet! OUCH. Looks like ply wood it is. I am friends with a cabinet maker who can get me a dense, light weight plywood (3/4")at cost. Any suggestions of the particular wood to use?
Thanks for all of the help!

Jason

Re: 74 Seacraft Tsunami
 

I'd consider a windlass but would still like to restore things to how they were/should be. If it's still inconvenient a windlass may be the answer. It is one more item to maintain though. Another thing to break or go wrong. The anchor on there now has an all rope rode (no chain) which might make things easier on a windlass as well. I think you still need to go up there to mechanically secure things though. The windlass should only be used for raising or lowering the anchor right?

Re: 74 Seacraft Tsunami
 

I apologize, I think I've taken things kind of off topic from Jason's original questions. I can't do anything till I know where I'm storing the thing and will post more about my questions once I figure that out in the next few weeks. Thanks for your help

Re: 74 Seacraft Tsunami
 

Got some work done. Monster removed off the transom.
http://i28.photobucket.com/albums/c2...eacraft037.jpg


http://i28.photobucket.com/albums/c2...eacraft038.jpg Removed Splashwell.

http://i28.photobucket.com/albums/c2...eacraft040.jpg Cut out 40% of the deck, Will finish Tomorrow.

http://i28.photobucket.com/albums/c2...eacraft043.jpg Are all Seacrafts built like this. The foam, Which is all dry, has been glassed over. All it tact with the exception of where I hit it with the grider. An epoxy? pile of material shown in these circles.

http://i28.photobucket.com/albums/c2...n/a93a5cbd.jpg

Since the foam is dry, I may make the repairs to the area I damanaged, and place spacers to get the deck up two inches, to make her self bailing.

Any thoughts? Hope I get more responses than I did to the deck question I had above [img]/images/graemlins/wink.gif[/img]

The deck was solid, the hatches were bad. I couldnt belive how much glass is in this boat.

Jason

Re: 74 Seacraft Tsunami
 

Finished the deck removal

Re: 74 Seacraft Tsunami
 

Someone's openin a can of whoopass on that deck !!! [img]/images/graemlins/shocked.gif[/img]

way to go !!

Re: 74 Seacraft Tsunami
 

Transom options. Drilled the transon in 20 different places today. Solid, but you can tell it got wet at one time. Wood is structurally sound and not damp at all. I am contemplating grinding (allready have) all the gelcoat off, filling all holes, and sandwiching laminating another 3/4 ply on the inside of the transom.

Now, I am fully enslosing the transom. So the cut out must be built up.

Questions,

Has anyone, filled the cutout with new ply, laminated it in place, grind, add second piece in cutout, glass, grind, and then place the last backer over the entire transom?

Or, how would you fill in the cutout with out removing the structurally sound transom?

This boat will see a bracket.

Thanks, Jason

Re: 74 Seacraft Tsunami
 

jason- looks like you are in deep. Your boat looks like it was in great shape and I dont know that it was necessary to take out the entire deck and raise it 2 inches. Most guys with 23's just re-direct the scuppers out the back of the transom and that will make it self bailing. With that said however your boat will now be that much better now that it is raised 2 inches. The trick will be making it look nice when you are finished. If the transom is solid like mine was then there is no need to open that can of worms. Just add the 3/4 ply to the inside of the transom and that will make your transom about 3 inches thick! Bullet proof. Thats what I did. Adding a bracket will be your best investment. If money is no object then go with the potter bracket and i would make a transom door to get good access to the swim platform. Go to hermco's site for detailed pics. I have a lot of pics on my site. take your time and go thru them and you will see how I built my transom just like you are describing. You will need to make a molding table soon. see jasons description in the begining of the site. Good luck and keep the pics coming.
