I have a 2001 Mercury 9.9 4stroke on a 14' Klamath which is under powered with 3 adults aboard. I have compared the parts diagram for the 9.9hp and 15hp of the same year, the only difference I see is in the carbs. The main jet, main nozzle, and float bowl assembly are the only difference. Has anyone had sucess in upgrading their 9.9hp to a 15hp but just changing these parts? The cost of the new 15hp carb is just slightly higher than the parts seperate, so I'd plan on purchasing a new 15hp carb. Any input would be highly appreciated.
I also looked for differences in the exhaust such as a restrictor plate but all appears to be the same.
Thanks,
