The shorty was part of the deal with the drive. I am aware that I may have to add a spacer. Just have to see when we get it in the water.

What engine are you running

CAB 02-19-2010 08:07 PM

Do you mean now, or what we are building?

CAB 02-21-2010 07:53 PM

Well, we just pulled out a 496HO. It was 68 mph with a 26 bravo 1 4 blade. We are in the process of building a 588 ci fuel injected engine. Merlin tall deck block, Brodex aluminum heads,crower crank and rods. It will be a nice combination when we get through. The carberated version of this engine made 750 hp and 780 ft lbs. It remains to be seen if this will remain the same with the fuel injection.

What rpm's were you turning to get 68 with a 26p prop

noyzee 02-23-2010 04:57 PM

what did you do with the ho? any info on it?

CAB 02-23-2010 08:32 PM

Was turning 4800 with the 26 pitch. The HO is for sale. 8500 with stainless marine exhaust. The boat with HO ran 65 with 24 bravo 1 at 4800. Put the stainless marine exhaust on and it went to 68 hitting rev limiter. Changed to 26 ran 68 at 4800.
