I posted this previously under another forum and just saw that there was a forum specific to Key Largo...


I have a 2001 Key Largo 206 with a 2001 Mercruy 150 carb'd engine. The engine is in very good condition - great compression (125 psi), cleaned out carb's, new plugs, Thermostats, water pump, filters,etc...

The boat (full tank of gas, 1 person, no gear) won't plane off until about 4000 to 4200 rpm and will come off plane under 4000. WOT I'm getting over 5000 rpm. It has a 15x17P prop which is original and was standard equipment when the boat was sold new. The boat just seems to be working hard for the performance it is delivering. Should I not be expecting so much?

Is this a prop issue?? Any insight would help, really scratching my head on this one

Thanks,
