Re: Yanmar 40 hp/SD50 seawater leak

It's probably the sail drive rubber seal between the hull and sail drive unit?
Usually there is a double seal with an electronic sensor that would give you warning of a problem.
Best have the problem looked at with boat out the water

My starboard engine ends up with the cavity underneath the engine full of seawater and overflowing into the bilge after an hour or two motoring at 2300 rpm. I thought it was the salt water pump, but had it rebuilt and there's no evidence of water around it.
The water outlet from the sail drive looks dry and no apparent leaks in the hoses to and from the heat exchanger. No water collects when docked, so I think the SD membrane is OK.
Any ideas where water might be coming from the bottom of the engine so as to end up in the cavity underneath or, possibly, from the forward part of the sail drive which would drain into the cavity?
