Water pump went out on river. Motor stopped. I have lots of money invested in the electronics of the motor. We just replaced all of the wiring and the stater box, new trigger, new switchboxes, new coil boxes, new water pump. Too much money to junk.<br /><br />We are curious about power head swaps. We were told that 90 or 115 hp were interchangable. Is this true?<br /><br />If do you know a used one?<br /><br />Any help would be GREATLY appreciated!
