so 34.2 engine intake valve

[SY Racer]

Hello everybody,

while checking the seacocks of my 1998 so 34.2 I came across the engine intake valve. The valves in general were replaced by the previous owner at some point in time in the past (was done by a yard, I guess). I already noticed (after buying the boat in April) the engine intake valve to be unmovable and left it as it was for the season. In the meantime I was able to move the valve, but I cannot close the valve, as the lever has not enough room and touches the engine foundation before being closed. Some genious at Jenneau decided to put the intake valve in te small room between the electrical main switches and the engine foundation.

I want to replace the valve now with a trudesign (as I already did with the holding tank outlet). Has anybody done the befor and is the enough roo for the somewhat bigger reinforced nylon valves?

thx

Hello everybody,

just for the records, I replaced the engine intake valve of my SO 34.2 in the meantime. As I mentioned in my original post, there is only very little room to turn the lever of a ball valve. I don't know if there was a valve installed by Jeanneau, but the valve that was on my boat when I bought it, couldn't be operated at all. You can see the limited space on the photo, with the lever of the valve already removed:

To replace the ball valve with an (even bulkier) trudesign valve was no option.

I went for a sleeve gate valve. These are not so common any more, but can work for decades, if of good (bronze) quality. Go for the red-white (sometimes also called red-yellow) brand if your want high quality (https://redwhitevalvecorp.com/product/204a-bronze-gate-valve/)

To install the valve I had to completely disassemble the valve, as there is even not enough room to screw on the piece.

The picture show the disassembled valve during the installation:

Congratulations, it looks like a tight fit.

Did you replace the through hull fitting as well ? …… just another potential problem area for large leaks. 

With hind sight, would there be a better place for the valve position by positioning a new through hull fitting elsewhere ?

My boat of 2006  I replaced all below water through hulls as well as valves,  the old through hulls crumbled when hit with a hammer so must have been weak, and I will replace mine again when it is time to replace the valves, may be with true design.

No, I didn't replace the trough hull fittings. They were OK. The previous owner had the sea cocks replaced some years ago.  Perhaps they already replaced thew through hull fittings. The ball valve itself (was stainless steel) was in pretty good condition. The problem was, that the yard didn't took into account that a valve is only useful, if you are able the move the lever . I'm in the baltic (with less salty water), so may be less corrosion than in other parts of the world.
