[QUOTE="wmk0002, post: 422757, member: 13975"] Nice motor and I agree with what was said above. I've got a 15hp Johnson myself on a 1648 and I get about 21-22 mph solo with the factory sized prop. With a lighter boat turning a few more rpms and having very little prop slip 25 mph is about the theoretical max my motor could achieve. If you want to prop it just right you will need a tach and if you want to calculate prop slip and toy around with some theoretical top speeds you can use the link below. You just need to find your drive ratio to use as an input. [url]https://www.rbbi.com/folders/prop/propcalc.htm[/url] [/QUOTE]
