I have seen some older threads re: 9.9 to 15 conversions. Now, it seems to me that the newer 15's share the same platform with the 20's. After looking at the specs on these, I am really curious where the differences lie.
Horsepower, displacement, bore & stroke, gear ratio, dry weight.....all appear to me to be identical. The only difference I see is the max rpm's at wot are 5000 - 6000 for the 15 and 5400 - 6100 for the 20.
Can someone more knowledgeable than myself about outboards (probably most of you!) shed some light on where the real differences are, and if that conversion is a possibility?
Forgive me if I have missed discussion on this topic, all of my searches have turned up the 9.9 to 15 threads.
Thanks, and what a dynamite site! Very glad to have found you all!
Cheers,
