No Luck on the search Gord but thanks for the link. I have contacted them via their contact page so we shall see what they say. I am in the Middle East at the moment so dont have the engine
number which is probably the first thing they will ask for. The manuals
are on the boat, workshop and owners, but surprisingly no Power Curve.
The boat is over propped with a 22" x 14", not sure what this means) RH Propellor on a 1.9:1 ratio gearbox
. I get heavy cavitation at 2500 rpm
. At 1400 rpm
she cruises along at 6 kts.
I am trying to determine if I should re prop, re engine
or both. I really dont need this engine size. It was suggested to me that a previous owner put a big prop and the larger engine option into the boat to cruise
fast across the doldrums at low RPM.
Anyway, that's the reason I am looking for the curve. If Perkins come up with the goods, I'll contact you with a copy.
