Bought a 99 coral 202 with a 99 optimax 225 last fall. In Excellent condition. My question is motor with prop setup. Currently has a 25 trophy. Prop to pad looks to be at 3". Best rpms with original analog gauge is 5300-5400, speed is 60-62. Half tank of fuel, with 2 adults and 2 small kids. Seems like with the research I've done that seems to be on the low end. It does seem to plane out fairly decent considering the max rpm. I have changed plugs, fuel filter. Merc mechanic did some lower unit work while it was there he changed fuel line, oil line and rebuilt the "lift"pump. Is there something else I can check, try a different prop like a tempest, or just need to maybe drop pitch? I read some guys are turning a 25 pitch with 225's. Thanks in advance for any help.
