I'm not an expert but I grew up on an outboard boat. To the best of my knowledge those motors are tuned pretty well for both performance and reliability right out of the box. You will end up spending a bunch of money and getting little return in horsepower. The best advice I can give is to sell your motor and put that money and the money you were going to spend in tuning into a bigger motor. In the long run it will cost you less and you also still get the reliability. 😎

More horsepower than they originally made? Or yours is down on power?

You have a chrome bore 2.4L, so there's not a whole hell of a lot you can do to it to make more power before things start getting stupid expensive.   

If it's running well and your compression is decent (120ish psi) it's healthy and if it's on the boat in your avitar, I'd leave it alone.  The best upgrade you can do is a set of fiberglass reeds from Chris Carson Marine Service, and if you're in the mood for premium fuel or even mixing AV gas, mill the heads to get the compression up a bit.  Chris Carson also sells reed spacers to stuff the crankcase a bit more now too.   

What are your current speeds?   How is the boat mainly used?   What are your goals for the boat?

Didn't have a phone for quite some time. Things are getting better every day (after falling from a roof in November).

PM sent.
