With the diesel it may have made 15-17knts. but the noise was deafening. After 6-8 hours of running the noise would get to you. I guess she'll make close to 30 now

I believe the noise was the reason the po-po went to the marine power 350's in our boats, especially if they were that loud!

Hi dsharp. Thats quite a coversion. Another member offered that there were a few jackshaft diesel made but no straight inboards after mine. She's coming along real good on a bottom up rebuild. New shaft/strut/wiring/tranny. Does yours have the tunnel drive? I would think that big engine would be a charger.

Hey Don, not to hijack your thread but did you put a new rudder in as well? Thinking about replacing mine this spring but not sure about a source, size to order etc. thanx, love this thread!

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.

FYI talk about a 6bt being heavy. THE 24 BLACKFIN CAME WITH A 636cubic inch 3208 Cat!

I thought they only put the 3208's in the 25 Blackfiin. Good to know they went in the 24 as well. I almost bought a 25 years ago, but there was about 5 gallons of oil in the bilge. I had my dad with me, as soon as he saw that he said get off this boat now and never look back.
