No i wasnt but i bought from a dealer. And i spoke to the original owner about boat props motors. Boat was from oregon with 700 hp. 28 lab would turn 5400 at 5 psi boost with 2 750 holleys jets 73 and 82. 1.5 gears xr outdrive . Boat is solid and motor is strong checked compression is great timing good . I would really like to turn up boost but im not real knowledgeable about blowers boost and hurting motors. Another thing i live in nm and its also been really humid another factor Richness im only getting 4 psi boost right now also

1 other thing how about adding a superchiller i have heard good things about them more hp and helps prolong motor. The reason why these posts i would really like to run 75-80 in nm i thought thats what i would have been anyways at least 70.

I'd personally work on engine tuning before messing with props. Get the boost and afr right, then move on from there.

I would ask Teague about your setup. They'll probably be able to point you in the right direction in terms of jetting and props, especially since they set up that motor. Also, they have all the superchiller kits which would definitely add some power and prolong the life of your motor.
