I must tell you that I started with a small tunnel hull with a 21 outboard once I got it tuned in it was fine but you need smooth water to run well if you get any type of wave the boat tends to flip over I then bought a 53in gas boat it is much better rough water no problem starts & goes runs for 45mins also has a clutch so it will idle in the water to check them out look at warehousehobbies.com might seem expensive now but in the long run it will save you time & money hours of countless fun also gas is $1.50 per gal instead of $15.00
good luck Scott
