It is a car motor made to rev it's head of and use up to 35 amps, no good for a boat as it will only last for about five minutes..........

It has car motor brush gear, but isn't a slot car motor as they are never round. 
Did you mean R/C car?

It could be somewhere between a 32T and a 27T motor,and will produce in the region of 16,000+ rpm @ 7.2V. If you ran it on 4.8V however,the revs would drop to around 11,000 rpm,which with a 25-30mm 3-blade prop will,if it's a balsa boat,give you run times in excess of an hour. That's what is in my Vosper corvette. :-))
