I know of at least one brand of in the 90's had a 9.9 and 15 in their line-up; the only difference was the jets in the carb and the cam shaft. Swap those and you had a 15 (but labeled as a 9.9). I have no idea if that's still the case. But I also wouldn't be surprised since they can basically make two motors at once.Why do you think there are so many 9.9hp motors? I’m he 10hp motor threshold created the market. It isn’t just Washington
Puget Sound is a federal water, so they want you to register your boat to use it there.I’ve read the 16 foot or more than 10 hp before. I fish out of a 14 foot Lund in Puget Sound. I content we don’t need to register it, but, It is registered. Well,… I am thinking of getting a 15 hp for it anyway.
Well, you're right. I miss read the 11th bullet point.Puget Sound is a federal water, so they want you to register your boat to use it there.
