All,
Perhaps many of you know this already. The white rubber washer, 10mm inside diameter, 15 mm outside diameter, that goes around the post and helps seal the seawater strainer (engine cooling loops) is no longer available. Jeanneau recommend replacement of the entire strainer assembly with a current-model Vetus 330 strainer, having 25 mm appearing to be the necessary hose inside diameter. I hope to install one this weekend. It's identical to strainers installed on later boats. Cost on this side of the Atlantic is approx. $100 USD.

Karl ,
Not sure if I understand what you mean , but are you talking about the seal of a strainer's lid ?
If that's the case and you could post a picture so it`s clear what you need I might be able to help you.
Regards

Yeah I'm confused about what was wrong. Last time I was onboard I found my strainer was letting in air because the large O-ring that sealed the lid. Happily I was able to get a replacement. If I couldn't then I would have had to get the Vetus 330

Exactly Hoppy , maybe it's this what Karl means.  But then again , the size is more than the 10mm he describes. Perhaps he has the new one already in place , which is a shame because these O-rings are easy to find in specialized shops. Not just that , it's also fairly easy to make one yourself with some silicone sealant , some soap or vaseline and 24 hours of patience to allow it to cure. Will be off line for a few days now as I'm ready to leave to Gozo (Malta) to get some fuel , internet access and make marina reservations for the next month . Hope to be at Pantelleria or Linosa by midweek if the wind permits. Regards |

I took it that Karl was talking about the combined strainer/skin fitting/valve that is installed in the hull, to which the raw water line is attached. It's a one piece bronze unit I believe. I replaced ours after it had corroded to the point where I feared opening and closing the stairs as the hoses moved a little and I was worried that it would snap off. New Tru-Design strainer, Skin Fitting and Valve solved that fear for good.
Apologies in advance if I have misunderstood.

Karl needs to stop by and explain himself  PT, this is the Vetus 330 unit that Karl was told to use as a replacement. The original SO40 unit has a bolt through the middle and the lid is secured by a butterfly nut.  I don't recall seeing a white rubber washer when I pulled mine apart, but I could be totally wrong. |

Sorry for responding slowly ... I was on the boat and preoccupied by all manner of chaos over the past few days. Here's the link to the strainer assembly:  or here: imgur.com/cCDA8tJYou can see what's left of the white washer surrounding the center post. It is the deterioration of this washer that causes the leakage. Perhaps one could approximate a replacement with the appropriate fast-cure substance, but I didn't have the patience for that. Hoppy provided a nice picture of the Vetus 330 strainer. Here's what one needs to know about the replacement: - List item 1
- List item 2
- List item 3
- List item 4
- List item 5

when mine was leaking i ended up removing the unit for my o-ring search. Later i thought there must have been some sort of o-ring on the centre shaft, but i could not find it. so once i found the large o-ring i refitted it all and added an o-ring to the shaft. it prevented me from sealing the lid properly. i then removed the o-ring and it was fine. The big test will be to see if it has let air in over the past few weeks I've been away and what happens when I use the motor more than I did at the time I "fixed" it. I am happy to avoid "upgrading" to the 330 at all cost |

Colour me enlightened.
Yet another worry to add to the never ending list of worry items that I may (or may not) need to check.
It's a good thing I can't remember anything on the list, otherwise I'd never get to go sailing.

It's a good thing I can't remember anything on the list, otherwise I'd never get to go sailing. PT. Just glancing into the strainer is always part of my first engine start of the day procedure. I've done this to make sure it is clear of stuff but last time around it was also clear of water that gave me a hint to check it over |

Fortunately that check is part of my WOBBLE routine (Check the Raw Water, Oil Level, Starter Battery Voltage, Alternator Belt, Coolant Liquid level, Electrics (ie Alternator) and finally, give my lovely engine an affectionate kiss! I do love my Yanmar.
I simply miss-read/miss understood what Karl was writing about. Perils of skim reading.
I am going to go look for a spare now though, so I don't have to go through the frustrations he's just gone through!
Cheers Karl!

Ok , back online , now I get the picture. Also have a vetus 330 , and yes Karl , i would replace yours without hesitation . No hassle with the 330 types. Good luck Regards |

Onboard now, no sign of a washer on mine. I could not tell if the strainer had an airleak and emptied or if it was full, so I loosened the screw and then air seeped in. So it maintained the seal whilst I was away  |

Hoppy,
A good way to isolate the location of a strainer leak is to close the through-hull valve feeding the strainer. If seawater is found anywhere, following that move, there's a leak in the strainer or its inlet hose. I'm chasing a miniscule leak at the hose to thru-hul barb now. (The boat gods say: hey, moron, the hose is 15 years old, do you get it?)
Touchingo,
As boat frustrations go, this was minor ... more annoyance than anything else and a good part of that my fault for cramming all of the 12V system modifications into the limited space of the panel across the companionway last year, paying little attention to leaving clearances for future issues (yes, the 12V DC rebuild will be another future Hints 'n Tips article).

So it maintained the seal whilst I was away It's gone to sh!t now.... The strainer is not holding the water overnight now. Every morning the inlet pipe is empty I guess it was all fine when I first replaced the O-ring and it hadn't been stressed by running the engine. I'm in Stockholm for a couple of days, so on Monday I'm going Vetus 330 shopping |
