First of all I am looking for the information on on the differences between the 40 & 50 hp 45 ci OMC engines. My goal here is to try to do a low cost upgrade to a 40+ hp motor with out rebuilding/changing the pistons and crank...just yet. Any information or suggestions would be helpful.

what year. 80's and up use the same carb body, different jets, but you also have to change the link n sinc. you won't get much doing it.

your best solution, is to fine tune your boat and motors set up. proper balance of load in boat. proper height and tilt angle of the motor. proper prop for the load.
