Its been a while but this is what I got when I emailed those people. Thank you for your email
, and your interest in the Campbell Sailer propeller
Based on the information that you have provided, we would recommend a CS3RH14x8x1 for your installation
. This is a Campbell Sailer, three blade, Right Hand rotation, 14" diameter, 8" pitch
for a 1" shaft. This size is recommended to give you a good cruising rpm
and still have reserve for head wind
We have installed a number of this size Campbell Sailer for the Hunters with the 2GM20F engine
with good results. Your engine will run much smoother and the control in reverse will be improved with little or no walking.
And that is what they sold me. After I installed it this is what I wrote them back.
Hi, Norm well I finally got my prop installed that I ordered from you and I got to say I'm not impressed. (sorry) My full throttle RPM went from 3800 to 3000 (my tach) Top speed is really about the same 6.0 Kts. I can't even run it at 3000 RPM w/o it loading up and spuewing black smoke and suet in the water
. Never did that with the 2 blade
. I'm thinking its over propped. I'm not a rich man and can't afford to keep repitching. So my question to you is, will it hurt to leave it on there as long as I don't run it at full throttle?
If its better around the docks, and will keep the 5 to 6 Kts. against a head wind
and or current
it may be of some use to me still. I will say this it does seem to be smoother.
This was and still is on my 29' Hunter
7400 lbs Displacement
Looking back guess I was expecting a lot. Still using it today just can't run it at full RPM. I beleive I'm over pitched?
Hope this helps. Not real sure on the xmission I have.
