Time to get moving
 

Well I've dragged this boat around long enough. Time to tear her apart and fix it right. Any help would be great!

This is what I'm starting with

Time to pull the inner hull

Not too bad for a few hours this weekend. I know the people here will help me along with my little project. I've read most of the posts and man I'll learned a lot. I just wish i hadn't have cut the back 1/3 out before trying to pull the whole thing. Oh well one more little patch and the 2 will be one again. Any one have any sugestions on pulling the remaining front sectrion of the inner hull? From what I've seen on other boat rebuilds, there's nothing down there. Thanks in advance.

Welcome to the CSC Clan Corbett

Plenty of skilled knowledgeable help among the members onboard here. Keep the pics coming and use the search function to keep you motivated :cool:

Re: Time to get moving
 

Thanks Capt Chuck. I knew I could count on the members here to help me out.
I'm planning on recoring the floor from the bottom. Has anyone every done that before? Looks like most just replace the whole floor. I think I may be going againt the grain here, but the only mod that I'm planning is to raise the transum. If I remember right, this seacraft never had a self bailing problem. Any thoughts?

Re: Time to get moving
 

Yes they do now that we only have heavier motors, the inline 6 Mercs weighed nothing, like 268#. I have a 200 Merc on a 20 MA at 406# and it has trouble self bailing - maybe these guys can help you easily raise the floor an inch.

Another West Central guy though - PS the dark blue and black hulls look really good since it looks like you will do something there ;)

Re: Time to get moving
 

Tahnks for the info eggsuckindog. Know any local fiberglass suppiers?

Well I want to keep this seacraft stock. Maybe ill just redo it as is. Not raise the transum. Hell I dont know. I'm definately gona keep the color the same.Last time i was in this boat I was 8. That's almost 30 years ago. I was thinking on the way home from work that I could move the gas tank as far forward as the bilge will allow. Maybe that will offset the extra weight of todays engines. Speaking of engines... I'm looking in the 150 to 200 range. Anyone know what the biggest engine a 20 has had hung on it?

Re: Time to get moving
 

Your recollection needs to include MOTORS NO HEAVIER THAN ABOUT 300 LBS! That's what the 20' hull was designed for, and as you go heavier than that I believe it makes the balance and ride progressively worse IMHO, not to mention screwing up the self-bailing capability. The Seafari has a little more weight forward and may tolerate more transom weight a little better than a sf/cc.

Don't know what your usage/priorities are but mine are offshore use with good ride, and low noise and fuel burn in that order. The 20' hull will go airborne at about 25 mph in 3' seas, so I rarely use the 45+ mph capability of my 150. Ran my boat for over 30 years with an old lightweight 90 horse (at the prop) V-4 in some very rough conditions and was very happy with it, except for all the noise, smoke and fuel consumption! :D I suspect most folks would be pleasantly surprised at the performance of their boat if they could run it with 50-100 lbs less weight on the transom! I believe a 115-130 DI 2-stroke will provide the best balance of ride and fuel economy on the 20' hull.

Re: Time to get moving
 

The really perfect motor for it is the 150 Etec - I think thats what Bushwhacker has but thats just perfect

Re: Time to get moving
 

I have a 115 mercury optimax on my 20 and I love it. Yeah, maybe I don't have a super fast top end, but i cruise at 20 knots, the ride is nice, and after a 12 hour day of fishing the most I ever put in at the pump is 20 gallons. I wouldn't want to go any bigger, but that's just my two cents.

Re: Time to get moving
 

I agree with the smaller engine thought. I have a Yamaha 130 on my 68 20' SF. More than fast enough, I can draft a little less idleing the flats. Fishing with buddies in the boat it keeps the wieght down to stand in the back fishing.

Around here with all the manatee zones, we cant run too fast anyways

Re: Time to get moving
 

I think the 150 e-tec is a great choice. I just hope it's enough motor. My girls are still young so the way off shore thing will have to wait a while. I'm sure most of the time this boat will see some cruising and maybe pull the girls around on a tube or something.

Working 12 hour days the last few I haven't had any time to play. However today was only 10. So I bought a saws all and got to work. Did I mention I hate fiberglass!

Thanks again to all of you.

Re: Time to get moving
 

Anyone have any sugestions on coring material? I'm thinking of using Coosa Composites Bluewater 26. 1/4" for the deck and 1 1/2" for the tranom. Also is 1 1/2" gonna be enough?

Re: Time to get moving
 

PS the new 130 Etec is a V4 and may save some weight, there not out yet but you don't look like your hanging a motor in the next couple weeks either :D
These new DFI motors are quite a bit stronger than the old carbed jobs we were used to, plus the Etec's seem to be all pushing the 10% rule, meaning close to 10% more HP than stated.

I watched BW's boat pull away at the FT Desoto and admired how very well balanced the boat looked, maybe the bracket maybe not?

Re: Time to get moving
 

No where near ready to hang a motor. My goal is to hange it by x-mas. No presents for me this year! I'm just concerned that I'm gonna drop 8k on the motor and I'm not gonna be happy with it. Oh well, I'll cross that bridge when I get there.

Re: Time to get moving
 

Well another 10 hour day at work but i did manage to peal a little more fiberglass.

Did I mention how much fun this is?
More to come.

Re: Time to get moving
 

The bracket definitely helps keep it self bailing with the heavy motor, but my 70 qt cooler in the stepdown and 25# toolbox and other camping gear in the cabin also help! :D Balance when you're up on plane with flotation tank out of water is more important and would be even better with the V-4 which is 50-60 lbs lighter and ~$3K cheaper (better BANK balance! :D ).

The 150 E-Tec is actually a 165 as shown by the hp/torque curve in BRP's 2008 brochure, so it's overkill for the 20' hull, but great if you want a ~50 mph boat!

Re: Time to get moving
 

True statement on the 150 being a tad overkill, thats why I came back here when I heard about the new V4 130 Etec. Also good point on wieght in your Safari being firther forward but yours looks perfect. I wish I had 50 or 60 #'s less but do like the HP.

Re: Time to get moving
 

Whats that 130 weigh? Wonder if its close to my 99 375# 150 in weight. Its probably close to the old 150 in prop shaft HP.

Re: Time to get moving
 

The 130 is the same block as the 115, so should be about same weight, I think around 375 lbs.

As far as the horsepower "sandbagging" is concerned, this is just my opinion, but I suspect it's related to HP/cu. in., ie., more sandbagging on the more conservatively rated motors. On the 155 cu. in. V-6 block, it's rated at 150, 175, and 200 hp, or .97, 1.13, and 1.29 hp/cu. in., respectively. BRP's brochure indicates they've down rated the "150" by the full 10% allowed (It's really a 165). I'd figure they 175 is down rated by about 5%, which would make it about 180-185, while the 200 is probably right about 200. The 105 cu. in 115 V-4 is 1.095 hp/cu in and the 130 is about 1.24, so I'd guess that the "115" is really about 120-125 and the "130" is maybe 135 at most.

Re: Time to get moving
 

I did a little research on the (don't shot me) new sea crafts. Most of them are running 150s. You would think will all the advance in faberglass and other materials the new girls are lighter. But like most of you have said it a give and take. speed/economy/ride. Well I'm several months from getting one. Plenty of time to do a little more thinking and get more advice. Sorry guy no work on the boat this weekend. Honey dos! Gotta keep her happy.

Re: Time to get moving
 

We've got a 130 yammie (91)on a 74 scepter. Tops out at 40, light with two on board swinging a 13.25 x 17 yamaha semi cleaver 5800 rpm (thanks Fr. Frank). Light, with the top down, we get a touch over 3.5 mpg.

We get a little over 3.125 MPG loaded for bear with 3 guys, gear and a 150 qt cooler with 80 lb of ice, 40 gal gas, slight chop with bimini up.

Plenty of torque when you need it. We can't run faster than 30 unless it's really flat anyhow...

Just my two cents.

I believe there is 10-15% room for improvement when we find the "perfect" prop.
