Another Prop/Rpm/Speed thread

[jamesbalog]

Boat 1990 20 sport center console, boat has bottom paint... 2150lb dry according to the archives here. well the archives call for 2150 for the center console 20 fish. mine has 20 sport stickers, havent figured that one out but thats another story....

motor: 1981 merc 200hp

Prop: 19 pitch aluminum

Rpms: i can only get 4900-5000ish according to my tach. i have not tried another tach

speed: best ive seen is 42 on the Gps

The boat is usually ran pretty heavy. Kicker motor, 150qt cooler with fish and ice, 2-4 big guys, 10-12 rods, a cooler seat full of gear, 3 batteries, 100's of cranks in boxes etc....

I know the motor is truly only throwin 175 at the prop, im completely fine with high 30's low 40's, barely get the chance to run it at that in sloppy Lake Erie anyway. I just think it should turn quite a few more rpms and be able to do better than high 30s/low 40s

what kind of prop change would you recommend for trying to gain some rpms? would moving the motor up or down a hole help any? anything else you can think of?

thanks in advance
