Thanx for the info Don

IB`s ride so well.

IB's have their place, manuverable, fast, leaky?? I'll stay w/ the straight inboard or outboard.

Mine doesn't have the tunnel. I was a little disappointed in the performance with the 454. Seacraft makes a fairly heavy hull to start with so the extra weight of a big block doesn't help. I think it would have run just as well with a 350 and a 1.5 to 1 gear. It only turns a 13x13 now. I can't decide to put in a 350 or put aluminum heads and exhaust manifolds on the 454.

Hi sharp: We're not familiar with the hull w/o the tunnel (Yours) but as you noted the SeaCraft 23' has some glass in her. Sounds like you have what you aimed at. "30" is way above the speed of our Cummins. I'd run the 454 until it was ready for change out. Then decide. Don

I dont think any straight inboards were made without a pocket. Yours must be a conversion, the steep shaft angle from not having a pocket probably doesn't help your preformance problems.

Sorry Boatboy, I mis-stated. My 23' has a tunnel. Dsharp is the conversion. Sorry.

Don, Cool thread. I love reading the stories behind these boats, particularly the straight inboards. Got any more pics?

Hi Zen. Thank you for the kind remarks. More pictures coming as we uncover new interior paint job. She looks good!

Hi Don,

I always thought the 6bt was too heavy for a 23, but I guess. not. How many knots do you cruise at say 2400RPM?

I have 370B's in my Blackfin, so if I could fit one in my SeaCraft after the 350 gets tired that would be great. I could make a little Cummins parts section in my garage. :)
