#5508972 is the part number for the improved water pump kit for your motor. It also includes relief springs that have to be installed because of the increased pressure that the new-style pump generates. If you do it yourself, follow the directions carefully and perform  all the steps. It is best to obtain a factory service manual if you elect to do the maintenance .


The service manual and your operator's guide outline the maintenance needed for the 3yr.--300 hour intervals.


The propeller has to be determined by the rpm the engine can attain at full throttle with a normal load of people, gas, and gear. A tachometer is needed.
