With the restriction in Hong Kong of horsepower to 4 for anyone without a boating license (and the fact it's the biggest size I want to lug from my village house down to the water everytime I want to go out on the water), I was doing some research on how to make outboards "go faster".
One of the things I saw was "hydrofins"; did a search on this forum but didn't turn up anything. Basically plastic fins that are attached to the outboard near the cavitation plate to give some lift. All the ones I found online were for 25hp and above engines. Is there any companies making them for small 4hp outboards? Would it make any difference at all with such a small hp motor?
I'm using it to push an inflatable cat style boat; waiting for a new one to replace my storm damaged one. The new one will be a 3.3m aluminum floored zapcat style boat. 4hp is probably just going to make it putt along, not even sure if it would plane? So I thought if hydrofins would help I'd definitely go for it.
Any thoughts on other ways to make a tiny 4hp go faster is appreciated
