Could anyone help me identify this hose. Do I need a specific replacement or is there a generic type I can use? Thanks in advance for any help. Roy

I don't believe that is an original hose configuration so generic heater hose should be ok.
Gate valves are are generally not used on boats. You might look at it and replace with ball valve if used for critical systems.

Thanks for the info.
You might want to consider taking out all of the "extra" hose and gate valve setup at the rear of your engine. Even though your boat, and most other MkI's, came from the factory that way, it is not needed. I was told the original purpose was to provide a bypass of the water heater (not the kind of bypass of the water heater you would use for winterizing). I know of many owners (including me) who took out all of the "extra" stuff, and the engine works just fine (maybe even better?). I took mine out after talking with both Universal Motors (Hansen Marine in MA) and the factory. If you look at other boats (both Catalina and others), the loop for the water heater is plumbed between the thermostat housing and coolant circulating pump. My owner's manual did not show those extra hoses and gate valve. Just a thought.

Since you are replacing hoses anyway, you might as well get rid of this extra stuff that doesn't seem to do anything and just makes access in that are all the more difficult. When we removed ours I discovered the gate valves were frozen anyway...

Thank you both. Sounds like a plan. I just need to get something done in the next few days. Ready or not it hits the water in about a week.
I don't know why the M25 Owner's manual is not on the website, but here is a screen shot of how I plumbed the water heater after taking out all the extra hoses and fittings. Hope this helps.
Thank you very much. That will be a huge help!
The way Catalina did the hoses for the heater on our boat is shown in the second picture here:
