Hey all, you might have seen my other thread about my "new" hunter 40.5 purchase.

I am away from the boat but need to replace the raw water intake hoses as they're original and cracking. That's the only safety issue.

My question is this: does anyone know the type and size of the hose? It's a yanmar diesel 50hp. How universal are the water intake hoses?

Page 61 of the owner's manual posted on this site under 40.5 downloads indicates the coolant water line is 1 inch diameter.

I just changed mine on a Yanmar 110 hp. It was 1 inch inside diameter. I used the raw water/wet exhaust hose type. It was very expensive. About $500 for 35 feet. I replaced the hose going to
and from the strainer, which is far from the inlet.
