Thanks Louis. I would have been lost long ago without you.
Have had 6 views on the kill switch question but no response as of yet. I like that kill switch used on the jet skis. Probably better than the suicide throttle since it actually kills out the motor. I don't know if I could swim fast enough at even idle to catch a very light boat.
You have to keep your eyes open and know what you are
looking for...easier said than done of course.
Do your homework and develop a list of part numbers
of props that will work for you. Michigan Wheel catalog give Michigan Wheel propeller numbers for
many models so there is a starting point. Mercury
KF7 & KG7 Kiekhaefer propeller numbers are also
worth having. If you are prepared to find what you
are seeking you tend to get lucky and find it.
I call that making your own luck.
If you have access to a machinist and you like to
adventure...smaller bore props can be enlarged
or larger bore sleeved down. The important factor is rpm...matching prop to boat so engine rpm is at factory spec at full throtle. Trimming back tips
of blade to reduce area so long as done equally
and rpm stays close to spec.
Not a drill press and hacksaw job...will be turning
at high speed where minor variations will produce
major vibrations.
I had a prop sleeved that had previously been drilled
over size...required a holding fixture and a very
skilled machinist to pull it off. Prop was a brass
Michigan "racing" prop so worth the effort.
