First time I've posted here but already got a ton of info. I didn't really see this question asked/answered and I gotta figure something out. I have a coleman crawdad I converted to a micro bass boat. My problem is my motor. I had a merc 4 stroke 4 go I loved and it was stolen. So I bought a different motor to get by. Anyway, I got super lucky that a guy close by had an 08 4 HP that he thought had a fried coil. He figured he couldnt afford to fix it and sold it to me like stupid cheat. It's practically new and it took me 5 minutes to make her run. As is she pushes pretty well after the conversion. However, due to paying little for it I can justify get a prop and carb and convert it to a 6( I am aware of how to do this). However, how much difference power wise am I going to get? Any actual experience will be appreciated.
