Raw Water Pump

[mario f]

Greetings
My yanmar needs a new one 3gm30f.
Any recomendations as to replace or rebuild.
Or a better price of $400 ?
The leak is a small drip when off nothing when running.
Seems to be at shaft end , there is a small slit where water is dripping.
Thank-you for any help .

I had same problem for a 3HMF
Small leak also... not due to impeller or seal
just the pump leaking
I get a new one , I think it's worth the 400 $ and I sleep better...
Price was 400 and something

If it like most pumps that drip is a sign that the pump needs the seals replaced. just get a rebuild kit. if like my Perkins pump it takes about an hour if it is readily accessible. kit was about $40.00 on mine

sometimes your yanmar parts place will rebuild the pump seal for around 100 bucks. you can rebuild the seal yourself with a little effort for around 10 bucks. either way you need to remove the pump. beats paying 400 or more.

Depco Pump Company in Clearwater, Florida rebuilds all makes of marine water pumps; you will not know it is not new when you get it back.........
