hi i have an 800 ep converted it to nitro

i had a sc 1.5 it just stopped when it went in the water put a smaller prop on it went 5mph no good was told that was the engine to use

I have just put a 3.5 in it using everything as standard prop etc any tips before i put it in the water going to use 16% in it too as i have an air boat with a 40 in it runs fine on 16% i look forward to your reply regards stewart
