It is not going to be hard at all. You will have to pull the lower unit which with a 15 horse motor will not be that hard, so you could probably do it by yourself. Mine is a 150 horse mercury and i normally have one other person help me.

SOURCE: how tough is it to change water pump impeller on 15hp johnson

There is no special tricks.Unbolt the gearshift linkage that has access through the side of the leg.Usually a small plate.Unbolt the lower g/box.4 bolts I think.The box should then drop.If not,use a rubber hammer and be patient.Put the lower skeg of the g/box in a vice to make things easier.NOW.When you lift the housing of the w/pump take a note of which way the impellar pump lobes are curled.DON'T put the new impellar in the wrong way.It's probably worth putting in a new seal whilst it's apart.You spin the housing or imp. as you put it together.Use a small bit of grease for the initiall dry start-up.Put some very good grease on the top splines on the driveshaft.It goes straight into the crankshaft.If it corrodes,nothing comes apart.As you put the g/box back on,spin the prop so the splines go back in.There is no special alignment.Gearchange linkage and you go fishing.(take the prop off and regrease the splines on the shaft of it)Hope this helps

SOURCE: hard starting outboard

Remove the starter and have it tested at a marine dealer or autoparts store. If it is dragging and taking too much voltage it will not start.Dragging starter also will keep the engine from spinning the speed needed to start.

Hard starting on Yamaha 130 2 stroke. Always starts easily with ether. Choke works well.


This can have some reasons:
1 clogged carburettors. Too less fuel means a hard start.
2 Worn spark plugs
3 Loss of compression... On a 2-stroke, measuring compression is not an exact science. Have throttle wide open. No spark plugs, check compression on all cylinders. They should be all within 1bar from eachother...

1982 55 yamaha outboard ,water not coming out the water pump hole in strenght


First thing to check: Disconnect the tiny hose between the check outlet and the engine. Disconnect it at the engine side.
With an airgun, blow in the check hole from outside to engine side.
With an airgun, blow out the engine connection.
Start the engine, check waterflow out of the engine connector. If water, reconnect the hose and check the water at the checkpoint.
If still no water at the engine connection: replace the impeller!

15 hp outboard 2 stroke running with water muffs on,there is no water coming out of the **** tube? Check the impeller? where is it? Just bought the the motor.


Impeller is at the bottom in the housing. it may take a few mins for the water to come out of the tell tale hole. Ensure that your muffs are on properly and wait for a bit. Also insure that the hole is not plugged.

Impeller replacing on 1999 merc. 25hp 2 stroke


Should not be that hard. Tape up the ends so you can hold it with out getting cut, (if its ragged or sharp from damage). should be one nut holding the impeller on. If its to tight to hold try air or electric Impact wrench. If its bad you can tap with a hammer to help in removing the old one. If it turned on the shaft you will need to rent a puller. Repost if you need more help.
