Of course, don`t you read my posts? Zzzzzzzzz,,,,,,,,, fish on.

You bring good knowledge and that is what makes CSC the best.

well thank you !

Glad that this got smoozed over...:rolleyes::)
Otherwise GFS would have been wearing cement shoes! :p
Oh yeah, the fur hat is at the cleaners....

And to think I left without that hat and SeaMaster on the back of my GMC weenieee mobile.

60 ft. dive Sunday.

Lovin it.

Best Riding Seacraft
 

Like Carl Moesley said foot for foot its the 21!- No question about it
If anyone wants a ride in a 21 ring my buddy Steve or me up for a fishing trip....
I know where a 21 can be had, I'm sure it will cost you to own the very rare once in a lifetime dream..

Oh yeah, keep,rubbing it in. Ouch ouch!:D

Just bought a nicely restored Seacraft and repowered with 2015 175 Suzuki. Runs great, but I need some feedback on how to properly trim the boat out. I have tabs, and the engine is about 3 inches high. It seems to porpoise when I try to trim up like my old seapro 1700cc. Is the Seacraft supposed to ride with more of the boat in the water. So riding on the V?

What does the engine weigh? Bracketed? I'm assuming its a 20. Those boats like small light engines and brackets make a heavy engine worse.


Likely the boat is stern heavy. Tabs help but don't really get at the problem. If its stern heavy, think about moving as much weight(batteries, fuel) as far forward as possible. Somebody else should address engine height.

that engine weighs 474 lbs according to my research, if that is true then you are about 174 lbs over the recommended weight.

The original boat spec'd I pulled have a max motor rating of a 175hp. Of course this would have been a 380 pound engine back then. The boat doesn't porpoise unless I try and trim up like my bay boat. 3 batteries are under the console closer to the front of the boat. Real question is ride. Are these hull designs meant to ride with more of the boat in the water than a bass boat? My seapro hull was similar to a bass boat versus this boat

Prop might be losing it's bite. You say the engine is 3" high. I would lower it a hole and see what happens.
As far as proper trim, that depends on conditions. With my 18 in rough water, where I need to stay below a certain speed to keep the hull in the water(15-25 mph), I pretty much have the engine trimmed in and use the tabs to keep the running surface as level as possible(best ride). In really bad conditions(below 15 mph), no tabs and use the engine trim to keep the bow from stuffing. When I need to speed, I peg the throttle, trim the engine until there's a little prop ventilation, bring the trim down a little, then use the tabs to stay level and pick the whole hull up out of the water a little bit more. Might need to bring the engine trim down a little more.

As far as best ride goes, I bet Mr. Moesly would say to keep the running surface as level as possible regardless of how much of the hull is in the water.

A 4 blade Bay Pro III prop would do wonderful things for the ride characteristics of a 20 with a heavy motor on it's arse...

Thanks. I've seen pics of your boat before. Beauty. I agree. I think I was trimming up to far. I questioned the engine height, but was told by the mech of 35 years it is in the best position for performance. I'm gonna play with it a little more. I will have them lower if I'm not satisfied.

Maybe there is no answer to this question........

Why hasn't / didn't Seacraft revive the 21' hull as a re launched offering as a boat model ?
Seems no other 21' has the similar hull design, and was superior performer.

Yawn.... My guess is when Potter took the reigns over from Carl he changed the original design to "his" version and target products. Maybe there were creative differences or maybe Bill just felt his redesign was more marketable. In any case Bill decided not to for whatever the reason.

In the boat business it's not always about what works the best but what sells. New SeaCrafts don't even exist anymore. It does't mean they weren't great boats, just that nobody else wanted to run with the ball.
