I am kind of new to boating and need some advise on my 1995 baja 240 with a 454. This summer i would like to do some things to the motor. The lie-o-meter says that i am topping out at 55mph and i know its closer to a 65mph boat. I am currently running a 23p 3 blade prop but i also have a 24p 4 blade prop but i am not sure if it will help or not. I would like to just do some regular maintenance on the motor to bring back some of its life but am also looking at putting approx $1500 into some upgrades for the motor. What would yall do and what kind of power/speed can i expect. Thank you in advance for any help i can get.
