Working through the checklist, today I replaced the raw water impeller.
While doing so I notice that the hose from the impeller to... wherever
it goes (not being too technical), is leaking a little just after the
hose-clip at the impeller. The clamp may have been done up too tight,
and the hose is damaged. The system still works, but I feel I should
replace it before it gets any worse.

The problem I have is that nowhere in the manual does it say what size
this hose is, nor what type it should be. The current one is a soft
rubber with no reinforcement. The clip on each end says 20mm, I don't
know whether to get a length of 20mm hose and force it if it's too
small, or clamp it tight if it's too large (risking the same problem).
I'd rather get the right size.

Anyone out there got a 2QM15 can help me out here? Or can someone tell
me where I can find out what the correct size is?

Justin.


If the hose is not a custom Yanmar part, such as a molded bend, just
measure the hose (or take it off) and go to a marine store, or even an
auto parts store, and get a similar bit of hose.

If it is a fancy molded part, you'll probably have to go to Yanmar to
get the correct replacement (although a good auto parts shop may be
able to find something suitable.)
