Impeller and Gaskets

[masterfuji]

Hi Guys,

I am about to do a service on my engine and bought the impeller but did not get a gasket set with it. I am trying to find the gaskets to match but am unsure of what ones I need, or do I need a full set. The engine is a Mariner 80 4 stroke. It is 2007 but if it has 40 hours done I would say it is a lot. i just want to change the impeller itself but dont want to miss anything by not changing gaskets. The fact that the impeller comes without a gasket I was wondering if it does need it.

Any help is appreciated.

If its a paper gasket then there's every likelihood that you'll damage the existing one as you dismantle the impeller housing. They quite often sell impellers separately from gaskets for some reason oven though you nearly always need both together.

Thanks Erin. I will take it that I need to get the gaskets so first. How many different ones do I deffo have to replace?

In all the ones I've ever done there is only one flat gasket required. On larger engines e.g. my Suz 200 there is also a rubber cage around the housing. Even if you have something similar the rubber part is often reusable.

When I do them I change the thin gasket under the waterpump housing 27-8172771 £3.60
I take the lower wear plate off and clean in there and change the lower gasket 27-430331 £3.63
and the face seal that sits on the water pump housing over the shaft 26-816575A2 £6.62
