Exhaust Gunk

[Fed]

Are you plowing the bottom or power loading, sand & silt can destroy an impeller in less than a minute. Trust me I've done it.

I honestly believe power loading & unloading is the reason many people replace their impellers every year due to the sand it kicks up.

FWIW you could run that motor on double oil & still come back with a dry hub.

Hi Fed,

What do you mean by Plowing the bottom and power loading/unloading?

[Noelm]

Plowing simply refers to driving through sand/mud banks with the prop chewing up the bottom, driving the boat on and off the trailer is power loading/unloading.

Haven't done any driving through mud or sand banks. But i do drive the boat on and off the trailer

I never knew that it would have that much of an impact on the impeller.

In saying that though, when i changed the impeller earlier this year, it was in pretty good shape, no sand found inside the housing

Is it possible you picked up a plastic bag while idling around or is the overheat happening all the time?

Those bags are very sneaky, as soon as you stop they release & sink so you don't see them unless you're quick.

I wouldn't worry about the gunk just yet, concentrate on the overheat.
