SOURCE: replace water pump impellor 15hp yamaha outboard

Put the motor in neutral.On the leg of the motor there is a little side cover plate.Remove.Undo the bolts.This is the gear change linkage.At the cavitation plate,there is 4 bolts.Remove.If the lower housing does not drop,give it a soft whack with a soft hammer.When dropped,you will see the prop shaft and the gear linkage.Lower it all the way out.Its easy to work on if you put the lower skeg in a vice.Take the water pump apart BUT!!! have a look at which way the impellar blades are pointed.Grease the new impellar as you put it back in and turn it at the same time to get the nodes in properly.Heaps of grease to protect all the bolts.Makes it easier next time.Hope this helps

Prop shaft. You have to remove the bearing housing cap. reference number 70. Remove the bearing housing. reference number 60. The bearing housing will need to be pulled out buy using a puller. If it was in salt water it can be difficult. Pull the prop shaft and clutch dog assembly.

Is removing the lower end of a 15 hp older Johnson to get at the impeller as simple as removing the four bolts. Model # J15rcrm


There is also the gear change rod to undo.Look on the side of the leg,for a small plate.Inside it,is where the connecting bolts will be.Be in nuetral when you undo it and put it back together.On the water pump.Pay special attention to which way the lobes on the rubber impellar are facing.Wrong way around and you will damage the new impellar.Hope this helps
