the boat is a 87 the motor 86. I just rebuilt the motor over the winter and the only thing I really changed was the intake reeds. I went to fiber reeds. The motor is a 2.4. I am turning almost 6200 rpms at wot. My prop is currently a 14.25 X 25 in pitch. The prop is just a regular thru-hub exhaust. I am wanting to put a bobs nosecone on the lower, and go to a 27 or 28 in chopper, and see if I can get up around 80mph. With the nose cone I can get the motor higher out of the water. Right now, it is sitting pretty deep though. I will send you some pics tonight when I get home. Let me know if you know of anyone looking for a boat like mine. I want to sell it so I can go back to school
