propeller

Sailors: I've been looking for a more suitable propeller for my 8 hp Merc mariner outboard, one that will give a bit more engine speed for a given throttle opening when pushing the sailboat. The idea is to reduce plug fouling. I e-mailed Michigan Wheel and they no longer carry the larger-diameter, lower-pitch propellers that Merc lists for this outboard. They suggested that i check with dealers to see if any had them on the shelf still. I did some e-mailing without success. Can anybody recommend good propeller dealers who might have some small-motor props in stock? Chris Campbell

hello, Chris.... if i were looking for an odd-ball screw; i would take the number and go to the "Boat Part's" section of e-bay. once there, find the sub- catigory for propeller's and or engine parts. then start looking...... it may take some days, weeks or even months.... but i never let that stop me. fiver ************************** --- In Ca… [at] yahoogroups.com, Chris Campbell <clcampbell@...> wrote: > > Sailors: > > I've been looking for a more suitable propeller for my 8 hp Merc mariner > outboard, one that will give a bit more engine speed for a given > throttle opening when pushing the sailboat.

Chris, Mercury offers 9x7" prop for your Mariner 8, assuming the s/n is over a197112. It is p/n 48-828152a12, and retails for about $93. Any Merc dealer should be able to order it for you.

The Merc. manual for this motor lists two others for heavier boats--both 9-3/4" diameter, one with 6-1/2" pitch and one with 5-1/2". Mich. Wheel no longer offers those. I've been trying to figure out which would be the best compromise between operating efficiency for the motor (getting the RPMs high enough to operate without fouling plugs) and reasonable gasoline consumption. Power really isn't the issue. The Merc. book gives some weight ranges for the props but judging by their rules the standard prop (which i have) shouldn't move the boat at all. Any idea which prop. would be best for a boat with a specified (hypothetical, I know) displacement of 4,750 lbs.? Chris Campbell
