Ok I know better than to try to hop up an outboard. But.... I have this great running 4 hp 4 stroke that will get my inflatable up on plane with 1 person in it. But is just a hair shy of pushing 2 people up on plane....

The spec sheets say same bore and stroke and the only difference is electronic spark advance.... Any one ever try to turn a 4 hp 4stroke into a 6 hp 4stroke?
