Hello,

Does anybody know how to convert a Mercury 4hp 4 stroke into a 6 hp.
Motorbloc and cu are the same.
The WOT of the 6hp is approx. 1000 rpm more then the 4 hp.
Thanks for any help

I had one of these on a small dingy, and mounted a Garrett turbo on
it. It made 65 hp, and would push that little dingy 80 mph. It was
always fun to watch the locals as I "fly" into the bay.
