I got a 3.0L 4 cylinder Mercruiser
besides junking it, what can be done to improve power? It's rated 135 hp how can I get it up to 200 ish?
I don't have the room to throw in a 6cyl w/o lot's of enigne compartment work. It's in a 19' cuddy by Maxum. 1998 1900SCR
just looking for addtl. resources, not much to be found on these engines for upgrades.
