need yanmar exhaust help

Yanmar 3GM30F 27 HP 1992 on an Allmand 31 1982

noticed bilge pump running very often while under sail. Saw water coming into bilge on starboard side after heeling to starboard then going upright again. Eventually noticed slight bit of water on sole deck around base of stove area.
Noticed exhaust valve does go under water at times.

Back at port used garden hose to find problem.....exhaust hose leaks for at least 6-8 inches inside stern wall.

Very hard to get to.....even to find the problem.

My husband is thinking of cutting an access hole in the rear lazarette so he can reach the end of the hose where it exits the boat. He also feels that since the end of the hose has deteriorated, there might be a problem with the rest of the hose also, so perhaps he should replace the whole thing. Not sure how to access the front end of the hose.

Suggestions of how to repair/replace exhaust hose would be greatly appreciated..
Thanks.

Is there any such thing as a temporary quick fix? Will have more time to deal with problem in a couple weeks.

Forgot to mention...problem was probably there last fall, as I remember seeing the trickle of water on sole deck but thought it was somehow related to icebox leaking.

Quick-N-Dirty versus Right Way

The right way is to replace the 6 ft or so hose from the muffler to the exhaust port in the stern of the boat. It is not difficult, but will require you (or your hubby) some belly and back time to get the hose off.

If you need to limp into port somewhere or must have it working until you can fix it properly, you can tightly wrap Duct Tape around the hose over the crack. If done right, it will significantly slow the water flow into the boat, but probably not eliminate it. However, if you can wrap tape around the hose, you should be able to replace it.

Can't help on the access port stuff for your particular boat, but you should be able to get to the stern end of the hose through the transom locker/lazerette and the muffler end in the same area as the stuffing box.

If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.
