Yamaha Flush point- problems

[Iron Dials]

I'm looking for peoples experience regarding the flush point on Yamaha outboards.
Sailing club has two 15hp 4 strokes. Both have had their hoses broken off the flush point.
While the engines live a hard life, as club boats do, I'm wondering if this is normal or possibly the result of excessive misuse?

I've included image, I think.

Any experience or suggestions appreciated.

The design doesn't allow for any miss use very prominent better when the plugs in the leg out the way

[Iron Dials]

You're right there, it's designed with a loving owner in mind.

I asked the question badly in my first post, I'm more interested in knowing what work-arounds, if any, people have come up with to deal with this weak point.

I'm not interest in trying to blame someone for misuse, just want the problem to go away if we can do something.

Why would they use the flush point and not muffs and a hose, flush points are for boats on moorings and don't do as good a flush as muffs.

I'm not interested in using it, just afraid that if the tape becomes undone there would be a loss of the cooling water through the hose, thus reducing cooling in the engine = €€€€€s

Hoping to find a more permanent solution, maybe the hose can be disconnected and the connection closed further down inside the leg.
Maybe it doesn't matter if it comes adrift.

Just trying to tap into the wealth of experience on the site.

Cut the hose inside the hood and plug it with an 8mm stainless bolt.

Is the hose garden hose diameter if so have a look on hoselock stuff should be a blank fitting.if not plumber merchants will have something

[jonp]

Why not simply replace it with a new fitting so it doesn't look bodged up.

[Iron Dials]

Yep, that's what we may do and if it was my engine definitely.

But, before spending the money, I thought I'd ask if this is an isolated issue (probably) or a recurring problem- if so how have people addressed it?

Both Yam 15s have the same damage, we only have 2, so 100% failure rate. Seems unlikely in the overall user group.

[Burgie]

We don't use the flush point. We only use muffs, to reduce engine damage and untrained people to do it. If used on sea water muffs are the best so you have a real deep clean. As a user said above, bolt it. One other problem for us is that sand can easily get in the flush points, which we don't want in the engine.

My 115 has about a 3/8" diameter rubber hose. Way smaller than a garden hose.

The damage has to be from abuse. Mine's going strong after 10 years.

You can simply plug the hose off with any object that fits somewhat securely (a pencil would work) and secure it with a zip tie. I've run mine after forgetting to reconnect the adapter to the blank plate; sprays quite a bit of water, but nothing damaged.
