A54 engine anti siphon vent


Sv Garulfo
 

Hi all,

Over the few years we have owned Garulfo, we came to notice that the anti siphon vent for the engine that exits in the starboard cockpit drain hole was a good tell tale of a restriction in the raw water line: 

when everything is clear (intake thru hull, vetus strainer, transmission heat exchanger, impeller, etc), the stream of water out of the vent line into the drain is continuous and silent,

when the flow is restricted, the initial spurting of water and exhaust gaz continues to the point of becoming annoying and I know i need to go and clean something. After clearing the line, the flow is back to normal. 


Do other A54 owners share the same experience? Do my conclusions make sense, or is it some kind of coincidence?

Any feedback welcome!

I have noticed the same thing. What you are noting is really important. I listen every time I start the engine.

I have that very sound and yes it is annoying. Looking to do a flush. This is the kind of tips we Amel owners need more of. Thank you.

Very important and astute observation. We do the same. Luckily we have little ladies who get paid for a weekly clean out of the salt water system. Also, first time I started the engine with Bill Rouse on board he reflexively pointed me to that siphon to look and listen to the stream in the starboard cockpit drain. Just yet another reason I’m so thankful we did the Amel school.

Over the decades with Amel, I sometimes sat in on part of the week long schooling each new Amel owner received as well as the somewhat shorter training I got on the three new ones I owned. The Amel guys always said to listen for the anti-siphon
"Clear it's throat" on start up and then 
" Mind it's manners" all the rest of the time.
A clever and catchy way to remember this important item.

Hi All,

I wanted to share an observation on that subject:

Despite having a very clear water circuit to the engine, we would sometimes get that squirting in the anti-siphon vent. 

After much head scratching, we realised it was due to the anchor wash check valve being stuck open, allowing air to be sucked in the sea chest through the anchor wash line. After cleaning it and removing all debris, it’s all back to normal. 

Hope that will help others
