When I bought my boat(new to me) I was told to punch it hard and quick when taking the boat onto a plane. I thought it was easier for the engine if you bring your rpms up slowly and go onto a plane slowly. My 2 stroke is a 90 hp. How hard do you punch it when going onto a plane? I was also wondering what the max rpms would be for a 90 hp 2 stroke. Wide open my rpms are around 4400 but I don't normally run it above 4000 rpms. I don't know a lot about outboards as you can probably tell.... Steve. And remember....Keep your tip up!!!
