Re: Muffler questions
2. A waterlift muffler should not exit below the water - this would add too much backpressure to the exhaust.
3. A waterlift muffler is usually just a can with the inlet near the top and the outlet extending with a standpipe to near the bottom. A waterlock usually has more of an "S" shape with some baffles in it.
4. If the inlet/outlet is too big for your engine, chances are the waterlock is to big - they are sized based on horsepower range and exhaust hose size. Vetus make a lot of smaller size waterlocks.

When I purchased my Vetus waterlock, they wanted me to calculate the total volume of the exhaust system. I suppose that was so they could sell me a unit which would contain all the water if the whole system backed up into it, assuming all the piping was full. Overkill?
Re Muffler question
i thought it is desirable to drain as much water from systems as possible when winterizing. . .
The Vetus waterlock has two drains - one for each part of the assembly. However, we usually run the engine with the water intake in a bucket of antifreeze. When the exhaust comes out pink then the h20 is out - hopefully. I have heard of some mechanics who blow out all the lines etc. with compressed air. I still drained my waterlock after running the antifreeze through. Haven't been to the boat yet to find out if my winterizing was successful.
