I have a 1979? I believe Chrysler 280 12hp long shaft sailboat engine with a 3-1 gearbox swinging a 35hp or so prop sitting around waiting for a good deal on a short lower unit. I found a 1991 gamefisher with a blown power head. The lower unit was a direct fit but no prop. New impeller, change LU oil and ready to go but need a prop. I don't want to spend a fortune for one though. A side note this 12hp Chrysler is a neat motor with all presto light electric ignition and electric start. It's also one of the quietest 2 strokes that I have herd. I did not know where to post this. I hope here is ok. I can pay with paypal or send a usps money order if the price is right. I believe it's a 10 spline. I would be interested in 8 x 9-1/4 -- 8-1/4 x 8-3/4 -- 8-1/4 x 8-1/4 or similar. Thanks.
