Is replacing your impellor really this easy?

**"G"** · 03-26-2013, 04:23 PM

The last one I did was on my 115 Yamaha four stroke....the impellor, gasket, and seals were about 40 bucks......the boat place wanted $250 to do it.....so yep you will save money. I try to replace every three years even if the pee hole is still putting out a good stream.

I've been watching the stream on my 90 expecting to have to do this at any time now. It's an '08 model so it's due.

That video makes it look really easy so long as you have something to hold the foot while you're working on it.

Done mine on old boat for yrs by myself a few times.. It's a 200.. Nothing to it

Do you normally just replace the impeller or the gaskets that go with it too? Lots of seals and gaskets here that the video said nothing about (3214 for a 90): MERCURY OUTBOARD WATER PUMP KITS AND IMPELLERS --Mastertech Marine--

Just called and they said the part was like $35 is all. I know I had the old boat changed out and it was pushing $200. Think I'll just go ahead and take it out tonight and replace it tomorrow after work. Shouldn't take but 30 minutes to take it out is all. I WILl video taking the parts off though so I can put them back in the way they came out. LOL

I replace the gasket and the seals involved with the impellor....I do not want to risk useing them over again after I have disturbed them....They do not cost that much....Like I said on my 115 Yamaha ....the total cost of gasket seals, and impellor was only 40 bucks. They wcan tell you at the boat place when you get your impellor what all you need to do the job

can be--but if your a first timer I wouldn't try it by yourself

I will say this....its not easy......and its not what I would call real hard, but it can be kinda tricky sometimes. Main thing is get the new impellor blades bent or curved in the same direction as the old one or it won't pump water right....then going back together you have to line up the driveshaft, the gearshift shaft, and the speedometer hose all at the same time.....sometimes that can give you a pain. Also one other tip......You have to pop the plastic plug so you can get a socket in to remove your steering trim tab because one of the bolts that holds your lower houseing on is under the trim tab.
