I just disconnected the water. Is there a reason to cap it off and fill it?
I’ve hit it with a IR thermometer after running 7 hours and it was 90 degrees or so.

I found something similar in mine. I capped off the raw water in and out and then filled the space with AMS synthetic 30W oil. Others on the list have done something similar. The V Drive has never gotten more than warm…

Hi all
I just cleaned out the vdrive for the first time ever. I didn’t know what to expect to see when I took off the top cover. What I saw was a solid black chunk that looked like old rusted metal. The yard manager suggested that I use delimer to eat the crud and then flush it with fresh water. I did it and opened the cover and there was the same black chunk. It was solid and had the shape of the cover cast into it. After two hours of scratching with a screwdriver, wire brush and using the shop vac it was shiny and looked like new. The amazing thing to me was that water even could pass through, but when I was flushing it out water was flowing full stream. I think that most of the funk was sediment from the creek. The bottom here is very soft mud and it seemed that it has protected the metal in the vdrive. The cleaning will be added to my maintenance list for each season to prevent it from getting so bad.
The primary reason that people have replaced the vdrive is corrosion from the raw water cooling, correct? If I don’t have any leaks and the cooling chamber is in good shape so I should be good for a while longer I hope.
The water inlet for the Cummins engine is 90 degrees to the center of the boat and the hose is in a tight turn to fit onto the the nipple on the raw water pump and fit in the engine box. When I was trying to tighten the hose clamp it kept slipping off, of course the soapy water made it slippery so after it has dried it may be OK. The hose should take on the bend after being there for a while but I was thinking of putting a 90 and a short section of hose to make the hose run with less stress. So long as I use bronze for the 90 and good hose clamps this should be a safe way to do it shouldn’t it? I just worry about weird stuff sometimes. The fact that the 90 will only be supported by the hose is what is bugging me I guess. Any ideas or input will be appreciated.Linus
