Yes they are fun if you get a chance check out my other videos . I'm not looking for any more speed with that boat but I would like a metal prop the same as the stock just so I know that it won't break as easy as the plastic prop

Specs read kv at 5400 x 7.4 = 39960 x .80 = 31960 rpm== .80 is efficiency is a round figure. Video shows it handles the rough stuff real well. Take care.** itook the kv off a site and thought it was high. I checked another site and saw 4500kv which was more like it. 4500 x 7.4 =33300 x .80 26640 rpm. Nothing wrong with that.

Why is your Shark jumping around in the water so much? Mine is super stable and looks faster than yours in the video. I know it's hard to tell speed from a video. Maybe it's because I am using a 4mm flex shaft and the prop is deeper in the water? anyways I doubt I could get mine to flip it's that stable in the water. I am running a 3s Lipo on a 2900kv motor.

In person the shark is running smoothly across the water just at the end it flipped

Dear all master,

Offshore electrics should have some shaft for you

Try using 2 blade p1.4 36 CNC Prop. or 37, if you using 3 blade 36 is fine, then it must handle 36 / 37 2 blade prop.
Using 2 blade raise out of water faster (Start Up) than using 3 blade. Motor and ESC also less heat.

I suggest using Tenshock / TP CNC prop 36/37 2 blade would be good for Mono
