Yanmar 3GM30 Water Pump

My water pump failed yesterday. Disassembled and went to put in the impeller from the Yanmar engine box that came with the boat. But that impeller looks for a key way; the hub in the pump is split and the impeller that came out is labeled Johnson 810. It has a set screw that goes through it and fits in the slot. Why would a Johnson part be in a Yanmar engine?

Re: Yanmar 3GM30 Water Pump

Yanmar pumps aren't cheap. I replaced mine on my former 2GM20 and I was shocked at the price. Some folks use aftermarket (Johnson?) pumps to save money. The only interfaces to the engine are the mounting bracket/pulley and the two hoses.

Re: Yanmar 3GM30 Water Pump

Yanmar doesn't make pumps.

The pump is different between the USA 3GM30 model and 'YEU' model. The "810" is the impeller for the YEU model. The pump is a Johnson F4B-9 (10-24509). Besides a different impeller, you'll notice the cam in your pump is not changeable. The good news, the YEU pump is cheaper (about 1/2) to buy.

Depco can help with the pump/parts.
Depco Pump Company

Cheapest I've found the impeller is:
JOHNSON PUMP 09-810B-1 - 6 Blade Johnson Pump Impeller Kit

Re: Yanmar 3GM30 Water Pump

I just bought the pump for $300 US.
Krappy pumps, some yanmar mechanics can provide you with an alternate pump of better quality and price.
