End of the day, its a matter of whats good for you,
i brought my boat as a unfinished project, most of the parts came with the hull alone with motor,
i remounted everything in the boat, put on some boat, and shes good to go and
parts are pretty easy to get if needed.
since running, the only thing to let go was a coil, and i did replace it with one for a Zenoah due to having in laying around for a spare from another boat
i wont say Zenoahs are not a proven motor, because they are. just doesn't mean they are the only thing out there.
if my hull didn't come with the motor i would have gone with the Zenoah.
but it didn't and since using the CRRC motor, im quite impressed. starts well, good on fuel, speed is good with the hull. and i have no trouble hooning around on the river. end of the day its all about full and im having it
Note, i haven't set it up for racing, i did install a clutch and water pump,
as i do live been able to start it in the water, come to a stop, and go out and burn 30 minutes of fuel at a time
