Hi! Unfortunately, i had a boat hull (FSR-V) with underwater prop. This engine is too weak for a submerged prop without a gear. I have to build or buy a hull where the prop is partially submerged, like the offshore FSR-O models. For this engine a surface drive (hydro)prop between the size 29-34 mm would be appropriate without a gear.

what prop do you have on it?
I have a 30mm direct on the crankshaft (no gears)
it just pulls it, a 40mm is way to large.
I have a Kyosho .15
