Dumb question? How do you install the intake backwards? Also like the idea of the non valved anti-siphon. My cockpit scupper us tapped so the bypass flows into the scupper. No sticking valve issue easy and reliable.

Re: The saga of my beneteau 49

The intake strainer is fashioned like a scoop. On a power boat it would face forward to assist the water flow but on a sailboat it should face aft so water is not forced through the engine when sailing.

Sounds more than plausible, my Bene 473 has the cooling intake offset to port of the centre line. If the OP has a similar set up, that would put the intake deeper on a stbd tack, and more likely to assist the movement of water through the raw water system.
At least the boat is in warm water and will be easy to check.

Re: The saga of my beneteau 49

What is the relative position of the muffler/water lift compared to the engine when heeled etc. Are you sure that water from that getting back to the engine even if water isn't coming in via the exhaust outlet?

Re: The saga of my beneteau 49

I would pull the exhaust hose the the cooling hose going to the riser off while under simuilar conditions, then you will know before to feed it another motor

Okay strainer pointed fwd I could see. Maybe someone reversed it. Intake reversed would be very odd. At this point it sounds like the water is coming in on the intake side. Easy to shut down the thru hull at the intake.

Given this is your third engine to which this has happened, it seems more than reasonable to assume the engine install is fine and something else is the problem.

The Beneteau people are telling me their boats are fine (mine is not!), so I am on my own on this one.
Obviously this one isn't! I would talk to them again to ensure they understand the problem could only be something unrelated to the engine, i.e, their boat and ask them how much they value customer relations and internet discussions such as this.

Re: The saga of my beneteau 49

I would definitely want to find another owner and ask to look at the whole system... see what's different..

Re: The saga of my beneteau 49

One thing I do to make sure I don't run the engine without the throughhull open is hang the key off the valve handle after closing it. Pretty hard to forget doing it that way. I can be pretty dense sometimes and this has been effective.

Re: The saga of my beneteau 49

ok, you got me on this one.

close the cooling water intake when starting the engine. wouldn't that cause the raw water pump to run in a dry condition? and isn't that bad for the rubber impeller?

Re: The saga of my beneteau 49

Sounds like the prop is turning the engine thus the impeller, and causing the flooding. How do you feather your prop?

Re: The saga of my beneteau 49

After I stop the engine, I go in reverse for 10 seconds which stops the prop from turning. AS I have a Maxprop, the prop remains immobile regardless of the speed and what tack I am on.

Re: The saga of my beneteau 49

Thanks for the advice, I will now close the intake when I go for long sails in order to avoid any further problems.
I am thinking of starting the engine with the intake shut off and immediately open it.
Is it safe for the waterpump impeller?

Re: The saga of my beneteau 49

CAn you be more specific? You mean the water is flowing in the heat exchanger in the wrong direction?
We installed the water hose the exact same way as they were installed originally by Beneteau, so , if they made a mistake we are repeating it.
I am trying to get help from Beneteau to see if they can give me some advise, but so far , nothing.
