I once had 15hp Johnson with the long shaft extender, and I changed it over
and it didn't amount to much work, although it was a long time ago and I
don't remember the details.
$50 seems pretty reasonable for the kit. I sold my leftover kit a couple of
years ago for over a hundred.

Hey group!!

Thinking about getting a small engine for my horsepower restricted lakes,
9.9 to be exact. (Might get a 15 and put 9.9 stickers on it) I think I
found one locally, I think, but it's a short shaft, and I need a long.
How hard is it to put a 5 inch extension kit on this thing? Anyone got
any experience with this?

TIA,

Doug
