Impeller Plate Gasket

First time for me. Putting a new impeller in my Yanmar 3GM. I took off the impeller cover plate, put the new impeller in and find I do not have a new gasket. The old gasket is intact. Can I use it? Should I use a gasket sealer of some type (Permatex?) I'll have to order a new gasket and the boat is scheduled to go in tomorrow. This is a raw water cooled fresh-water boat. Thanks for the help.

Re: impeller plate gasket

Soak the gasket in MMO for a few hours. (Miracle Mystery Oil) It helps it to swell up a bit and will usually seal. Especially if the gasket is intact. But the other thing is, isn't your through hulls equipped with valves? You can always shut them for the launch and just don't open them until you get the impeller fixed.

Re: impeller plate gasket

Chart paper has been known to work for a gasket. No gasket won't work so don't try it. If the old one is not broken it might work. If broken it won't work but might limp to a very close destination.

Re: Impeller Plate Gasket

the old one should work if not broken. They are a specific thickness, if you put a home made one in that is thicker it may be worse than reusing the one you've got.

Re: Impeller Plate Gasket

I've even heard of using the cover page of a glossy magazine as gasket material in a pinch. For those old timers that remember when a car/truck had a distributor, points and condenser, I recall using a match book cover to set the gap on the points.

I can attest to that based on personal experience. A bit of silicone grease on the gasket makes it even better. Also smearing some silicone grease over the impeller and inside of the pump housing helps it prime and reduces wear when you start the engine the first time.

Re: Impeller Plate Gasket

I heard a joke concerning a waxed cereal box gasket today, except that apparently it works.

Re: Impeller Plate Gasket

sailstoo,

The old intacted gasket will work. You’re lucky, they usually rip.

In the future you may want to think about a speedseal that has the reusable gasket built in.
SpeedSeal replaces the Impeller cover and makes impeller changes faster and easier.

Welcome to Speedseal How it Works

Re: Impeller Plate Gasket

The thickness of the gasket is critical to the efficiency of the pump.
