Yanmar 18hp Exhaust Hose
On Friday motoring out to spend an overnight in Newport we heard this 'squeak' at about a 2 sec interval. As most of you know, it is better not to let a strange noise go unattended. So I handed the helm to Mechele and went searching, and found that the yanmar exhaust hose was rubbing on the zip tie fitting, which is attached to the hull. The tie is at the point just before the hose travels upward then down to the thru-hull fitting. So I clip the tie, and of course, the rubbing on the fitting was wearing thru the hose.
Question, now unsecured from the zip tie, the hose was jerking quite a bit every time the water/exhaust cycled through, so much, I did not want to leave it unsecured. Is this normal?
So, for a quick remedy, I wrapped the hose with gorilla tape over the wear spot, and resecured it with a zip tie, tight enough that it did not move, given the limited supplies I had on board. The wear point is very shallow, and I do not think the hose needs to be replaced. Thoughts?
Question: Any suggestions what I can use to cover the hose to prevent the potential for further wear?
