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.

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.
