I'm a new boater and just discovered that I must replace the exhaust manifolds and elbows on both 4.3L MPI Mercruiser engines on my 2003 Sundancer 280. I have done lots of automobile engine rebuilding but have zero experience with a boat. How does one drain the raw water from the heat exchangers and exhaust manifolds, prior to manifold removal, without sinking the boat?
I am concerned about a siphon effect possibly drawing sea water into the bilge from the exhaust port. Any advice is greatly appreciated.
