Hello Captains,
I've been trying to resolve a problem. 4 years ago a mechanic replaced and my starboard inboard engine on our 1996 310 express cruiser and didn't connect the water heater hoses. He came back and connected one hose to the front and the other hose to the rear of the exhaust manifold. Obviously there's no flow, so there's no heat. He's useless (being nice). Being in South Florida and having electric heat when docked it hasn't been a big problem. However, I'm working on replacing the exhaust manifolds soon and would like to get this corrected. The mechanic may have left off necessary connections or hoses on replacement engine.

I've scoured the internet and viewed all the manuals and plumbing diagrams, but can't find any details as how to properly connect the water heater hoses to a carbureted Crusader 350 XL engine that is raw water cooled. Tried contacting Carver and they were of no help.

Would appreciate any help with pictures or pointing me in the right location to see manuals or diagrams.

TIA, Ron
