It's got a pull-starter and side exhaust, 2 pluses for a RTR boat. Contact Glenn Quarles but probably not this weekend as his wife is shooting for a SAW record in Sport .12 hydro. Martin Truex Jr. is rolling into town to help them out plus probably aiming for a few more himself. You might get a better price than the one listed.
You might have to get a bigger prop as that should have a lot more power and RPM. I don't know what prop for sure as if it has the 1/8" shaft you're limited to the biggest 35mm as anything bigger you'd have to convert over to a 3/16" drive.
These little engines love the nitro. I've run 65% in my little ones but I'm a little crazy, 40-50% would be good.
