Inboard exhaust system

[martinwill]

I want to fit a water cooled system to my twin cylinder diesel, but am limited with space and want to know if a water lock is essential or can i get away with just fitting a silencer with a valve in it and an exhaust skin fitting again with a flap on it. The engine exhaust manifold is above the waterline if this helps. also would it be a good idea to fit the exhaust hose to form a goose neck in the transom box or fit a dedicated goose neck. Would appreciate any thoughts on the mater
