crank mounted raw water pumps
Thought I would start a separate thread.......what are the pros and cons of this style pump?.....anyone retrofit these? There has to be better than those pulley driven, plastic, hard to get a pump designs......are there any kits available for mercruiser etc?...what say you folk......
The above is strictly my opinion always based on years of doing...remember to support local business , it pays back.

Re: crank mounted raw water pumps
Gee, I think I have seen models that are brass or metal and not plastic. Must be a replacement.

Re: crank mounted raw water pumps
What happens if/when the direct coupled pump seizes?
At the very least, a belt offers some protection.

Nope , these are OEM plastic housing raw water pumps......I believe quite common......I have spares with merc right on them.

Re: crank mounted raw water pumps
Where do you boat? I've heard some say that brackish and salt water are murder on them, but I didn't see it.
Had my 1988 2807 with Mercruisers impossible-to-get-at pumps in Lake Michigan, 3 years on the Chesepeake Bay, and 3 years in the Pacific Ocean. Never had to replace a plastic housing.
My Cougar has Mercruiser pumps on them and they serve those big engines just fine.

Re: crank mounted raw water pumps
Great lakes, I am getting older and have some health issues ( back) , so if I can make maintenance a lot more easy I am all for it, as for the pump seizing, I couldn't answer that.....
