Syphon break problem

[Seagreen]

Well VicS, I've just seen the system in action, and you either get a small dribble out of the secondary port, and most of the water going out of the exhaust, or all the water coming out of the second port. The hosing leaks at the valve, too, which doesn't help and I'll sort that out tonight.

As for the connection between the exhaust pipe and the syphon system, that my just be a fiction on my part, but again, I'll check that up tonight.

If you run the engine for long, especially under load, with all the water going out of the secondary exit, then you run a considerable risk of heat damage to the flexible exhaust and waterlock esp. if it is plastic.

That has got to be the understatement of the year. /forums/images/graemlins/frown.gif

Hopefully this is not a hi-jack but a slight diversion of the thread. I need to replace by water lock. My system is already setup with a anti-siphon valve and a large gooseneck loop before the hull exit. How much below the engine exhaust outlet do you think is safe for the entry into the water lock. With the current water lock the drop os probably 200mm but the replacement water lock (Nanni) is taller and the inlet would be only about 100mm below the engine outlet (and water injection point).

Any advice please?

I think that will be fine. The watertrap is essentially just a reservoir, with the outlet from below an internal baffle.

Take a look at pages 144 et seq. of the Vetus catalogue

Thanks Vic
I'll keep going on the project.
