Yanmar saildrive diaphram

Recommended Posts

We replaced both. Wasn’t as hard as we were told to expect. And the old seal was quite stiff and overdue.

 

As to the securing rings on the second seal being weak; I couldn’t agree more. We had a crack in the exhaust elbow a year ago on a long overnight trip which filled the boat with water to the floorboards before we knew about it. Consequently, with the cracked secondary seal, the cavity between the two was full of seawater and the rings you mention we’re so corroded as to be virtually non existent. (Also establishing the water alarm is NBG too. )

Just remember only an alarm, not an auto bilge pump - you dont want it auto pumping oily water into the marina, for example.

I had an issue some years back where in a flat calm we motored for quite a few hours, then Jo noticed water coming out under the engine compartment front cover. There was 300mm of water in the engine compartment due to a failed raw water pump seal. Since then, I've always had a water sensor and alarm. Checking every watch change is not enough....

I've just put a water alarm into my engine compartment with a saildrive. It's a battery operated one- battery last for two years so I'll replace every year to make sure.

They're cheap enough, just look up "flood alert' on the internet - cost me $14.

I  have it on a swivel, so I just turn it down to just above the floor when I turn on the seacock. Worth a try I thought
