I'm sorry for the confusion. I had planned on a
12x10 two blade prop. Then I found a 3 blade 12x6,
(which I didn't notice had a 7/8" bore). I ended up
using a 12x8 two blade sail boat prop. I have a 2:1
reduction on my motor. I need to check my rpm this year. I
started out with a chain drive (2:1 reduction also). It
worked great, but it made to much noise. When I went to
belt drive I think the extra friction cut my speed
down a little. <br><br>I hope to find time this winter
to write a short story about how I went about my
conversion. I have a few more picture I want to post some
time soon also.<br><br>Thanks for all the various info
you guys are posting here at the club.<br><br>Jim
