Hi all, I guess you are right the configuration is different!
Here's the thing, the parts aren't avail. anymore and I thought what I did would work, wrong. How depressing! I have been looking for a 2 cyl. short shaft with controls 20 or 25 hp for 10 years, with no luck! I have a homemade boat and I can't go with a 4 cyl. as it too heavy. My boat will only handle 105 lbs or less.
I should have checked into it further.....damn.
