Figured I'd give an update in hopes to help someone later down the line!
Got the new carb on it today.
Loaded with 2 people and gear the boat will do 13.5 mph, on plane. Tach showed 5200-5300
With just me and my gear it got up to 18-19mph. The tach didn't work when i did the run, it does...
Well going down a prop size gave me 150-200 rpm. The smallest prop that is made for my motor is a 6. Operating range for my motor is 4500-55500 according to iboats.

I adjusted the valves, they were all tight. After this i took the boat out and grabbed...
I have looked into the 15hp carb and everything I've seen has show that's the only difference. The carb is $200. I'm sure this alone the motor would pickup some RPM.
I'm wondering how much the motor being pretty low under the boat is hurting me, I looked again this morning and I may be able...
Hello all!
I recently purchased this boat to fish our local lakes which are all limited to a 9.9. I've done quite a bit of reading and feel like I have a good amount of helpful info in my current setup. I know this is a rather large boat for such a small motor but she just pushes around the...
