Can anyone with a 93 era 40.5 or similar tell me, picture would help, on which hose between the engine block and engine oil heat exchanger to install the Groco anti-siphon loop?
I am not much of a mechanic. The oil heat exchanger corroded through a couple of years ago. The water hoses that came with the new heat exchanger were not designed with a siphon loop. I believe Hunter added the loop. We were in a hurry and installed the heat exchanger without the loop (big mistake). Now I am not sure exactly where to put the loop?
My boat is a 93 40.5, hull # HUN40526J293. The engine is a Yanmar 4JH2BE. The loop was at the very aft of the engine on the port side, a little above the top of the engine with a small relief hose leading down next to to the prop shaft to drain to the bilge. I just can’t recall which hose it was on. A pic woud really help.
Thanks much,
Roger
