I have read several of these threads and found replies both for and against putting a 15 hp. carb on a 9.9. I am wondering if it would be worth my while to try and "upgrade". Will it help or hurt? I would like to get just a little bit more out of this engine. It does fine with just me in the boat, but if someone else is with me it is rather slow. I hate to buy a bigger engine right now. If anyone has performed the above mentioned "upgrade" let me know how it did. Also if anyone knows any other adjustments I can make to boost this little engine please let me know
