From what I read on the catalogue and price lists here. You could get a 25 from the factory with twin 255mercs. Those are Ford 351 Windsor’s making 255hp ea or 510hp (ok maybe 400-450). Your 5.7 Volvo made 320 max from factory…realistically 260hp. Stroking that 5.7 from a 350cc to a 383cc would have given you a big bump. You had half the max hp. To get the right Hp to balance I had to go I/O. I’m afraid I won’t have enough HP myself but I’m dancing the hp/tq curve vs reversion. I’ll report when I get her done. If I don’t like it, I’ll cam swap it, upgrade the intake, supercharge, or go even bigger…a stroked 6.0 or ls9. I really hope not.

Yes you were right it was under powered. There are some images that I have saved of 25s with twins that basically take up the whole back end of the boat with the cover on the motors. I knew that going into it but I always went the cheap route after my first restore where I put a new motor on that....all the other ones I restored I bought used engines. It’s a good boat you just need to have a big trim tabs....did not mean to belittle it... the diagrams posted that Big Fluke made tell the story. No lateral stability...it rolls on the outward chines... I spoke with him once on the phone. Very good conversation...he took a great hull for his area and tweaked it...a lot to make it more stable.
