The biggest problem with changing to a hi-torque servo is will it fit? At least, without a lot of changes? If so, then why not. The other thingy is that a hi-torque usually draws a little more 'juice' than a 'normal' servo. The average run time (depending on how much the servo is used) will probably be slightly less than what you are now seeing. That 'slightly less' is relative, but I seriously doubt if you'll really be able to tell a big difference, sort of. It'll also change the ballasting of the boat, depending on how big the thing is. 'Nuther one of those 'don't worry about it' thingys in most instances, but who knows?

PS - Don't ask me why it works, but painting the servo 'hot-pink' seems to make it stronger.
