Getting a '77 20' CC SeaCraft redone

syxx · #1 09-13-2011, 02:37 PM

Hey guys! Just found this forum and have been browsing and seen a lot of cool things! I own a 1977 20' SeaCraft center console that i use for charter fishing. I've had it for about 5 years. In fairly good shape as the original owner had it in storage for many years, all original gelcoat and such. I'm repowering as I currently have a 140hp suzuki on there that is about 10 years old and it's time. Just derigged and brought the boat up to the shop. I'm going to be putting a 250 yamaha 4 stroke on it. Having the transom raised and flushed, adding a bracket. The floors I am cutting out and making flush (no step-up in the bow) and raising them. Trying to decide how high to raise them - any suggestions? I'm thinking maybe just 3 inches or so, I'm hoping to get it to be more self-bailing as water accumulates in it pretty easily and has no way to drain out unless I pick up and run, or let it go into bilge. Putting a leaning post in with bait well, which I saw a very cool one on this forum by Nautical Designs (http://www.nauticaldesigninc.com/ima...0/IMG_0082.jpg). The console is going to be replaced as well, have not decided what I'm doing there, but definitely want something smaller as it is tough to walk around the boat with what is in there now (not sure if it's factory original). Some rod holders on the sides would be nice, and perhaps a seat up front, and small windshield preferable. Other than that, adding spray rails, and that's it so far. If anyone has some good ideas on a console, or other suggestions, i'd appreciate it! Will post some before pics following, and some as it goes along!

Unfortunately all my boat pics include fish with them as well! Maybe that's not a problem lol

If you're gonna hang a 250 4 stroke on a bracket, you better raise the floor about a foot. That 250 weighs about 580 lbs. I'm sure some others will give a more experienced opinion. Good luck!

Let's see . . . a 40% increase in motor weight, mounted 2.5' further aft, what could go wrong there?! Nothing like a little CG shift to make for interesting performance characteristics! Max speed of about 70, min planing speed of about 30! If you just make the boat about 3' longer and move the console to the bow, it might even work!

Nice fishes. Unfortunately, the only picture without a fish looks a bit disturbing for the fellow at the pointy end

Weight concern is valid, but sounds like your man has plenty of flotation knowledge. How fast do you really need to go with clients aboard?
Bushwacker put a 150 etc on a seafari w/ float-bracket and had to move a lot of things around to correct CG.
I think he touches 50mph and is usually loaded for camping. Not sure but I think the 20s were designed with a 300 lb motor in mind.
I know you didn't ask me, but a new Suzuki 140 or the etec/opti 150 is about as heavy as I'd go

Off topic, can anyone tell me why this thread so wide

HAHAHAHA! Thanks for "pointing" that out. LOL. Yeah, those bows sure have a sharp entry.

The files (photos) are too big. They should be resized, i.e. made smaller.

I just looked again. LOL.

The dude behind the console: Yeah, that's ok. I'll just hang back here and fish... while seated.

Floor is ripped up and going to be adding a new fuel tank, should get an extra 10 gallons or so, around 60 full so that will be nice. Floor is going to be 3 inches higher and flush through to the bow. Using foam glassed over so will be much lighter too than existing wood floor. I think I'm going to use Birdsall Marine for the console, seat, coffin box, and cooler. Leaving the small bottom cutout near the transom for wet storage, fish box, or whatever else. The hatches and basic transom layout is going to remain the same, however I am raising the lip around the back to be flush around. One thing I have not decided is what to do for a bracket on the back as I think that is how we are going to mount the engine - any suggestions? Here's what else I'm adding...

http://www.birdsallmarine.com/produc...r-Console.html
Going to add a windshield, storage doors on both sides with maybe a tray inside, debating whether to have a fixed seat or use a separate cooler in front for a seat, likely a cooler since I will need one for drinks and a box for storage as well. Will have side mounted rod holders on each side too.

http://www.birdsallmarine.com/produc...orage-Box.html
Likely go with 350 qt size, will mostly use this for storage as I am losing my deck box up front, where I keep my life jackets, cast nets, and some other misc stuff. Will be lockable to deck though easily removed as well if I don't need it for the day.

http://www.birdsallmarine.com/products/Ice-Chest.html
If i go with an ice chest for in front of the console, likely get the 18x18x30 for good fit. And match coffin box of course

http://www.birdsallmarine.com/produc...itMaster-.html
Includes backrest with 3 rod holders and 35 gallon well. Going to make a wet box for livewell pump so it will be submerged all the time.

I shrunk the one picture that was really huge, sorry about that!
And as far as the guy sitting on the cooler in the pictures there... funny story we were fighting a big sawfish for like 2 hours. Unfortunately it ended up winning 8P. Those things can be very stubborn and very huge, don't like to come to the surface!
