R25 heater circulation pump CM 10 or 30?

[jimbeam]

2008 R25. Can't find info in manual on the circulation pump CM 10 or CM 30. So old (13 yrs) label is worn off. Which is it, a CM10 or CM30 johnson pump? It's the small black pump below the step with coolant hoses hooked to it. Coolant hose from pump goes to the heater forward under the captains chair. Pump needs to be replaced. Engine is 110 hp yanmar 4jh4.

Hello,

Unfortunately I don't have the list of parts we used on that model in 2008. Looking at the difference in pumps it comes down to hose size and GPM. I would assume we used a CM10 but I would look at the hose sizes to ensure you are looking at the correct pump. Either one should work fine just want to make sure the fuse/breaker size hasnt changed. Hope this helps.

Thanks,

On my 2007 with the 110 yanmar the circulation pump is a jabsco Water puppy. You want the nitrile impeller.

On my 2008 110hp R25 it is a Johnson CM10P7-1.
