eberspacher exhaust position

[briandoc]

I am planning to install an Eberspacher in my Sun Odyssey 36.2 this winter. The obvious place in terms of electrics and ducting would be well forward in the port cockpit locker but this means taking the exhaust fitting through the side of the hull rather than through the transom, as seems to be recommended. As far as I can see, the exhaust would be at least 1 metre above the water line and there would be room for a decent swan neck inside. SOs do not tend to sail with the toe rail in the water, at least not with me aboard! Any comments, particularly from those who have installed on a similar boat would be very welcome

just be careful with your fenders or if rafted the boat next door. I've known a few fenders pop this way and damage to gel coat too.

I have exactly the same set up in my centre cockpit Moody. Works well.

My exhaust exits on the side of the hull and it works fine. Just make sure you have a good swan-neck inside.

If you haven't already seen it, may I suggest you take a look at Eberspacher's excellent Marine Heater Installation Guide. Most Eberspacher problems are the result of poor installation, and this guide spells out exactly how to do it properly - including how to size the ducting correctly for the particular heater.

I'd thoroughly recommend including a duct silencer - it removes virtually all the fan noise and makes for superbly quiet operation.

Our exhaust also exits on the side of the hull and works fine. The only problem is that it is really antisocial to run it if rafted up due to the noise and fumes.

many thanks for the expertise and reassurance - I'm off to drill a big hole!

My Eber exhuast is on the port side of my Halberdier....

It took me ages to work out that the reason it would'nt start was because the swan neck was full of water...happened twice now... Not a problem now I know !!!

Just certain sea conditions on stbd tack.

the marine installation instructions have a picture of a little right angled exhaust section fitting directly under the heater which has a drain hole, presumably to avoid this very problem - not sure how or why it lets out water but not exhaust gas though
