- 5.0 MPI EC Mercruiser w/ Bravo III
First season with the new Sundeck 220 (lovin' it), and I'm reading up on winterization/maint etc.
Flushing the engine seems very easy - hook up muffs, turn on water, turn on engine etc. No problem. Basically same as the outboard engines I always had in the past until...
Until the last step - from the Mercruiser manual:
"Remove the saltwater inlet hose from the seawater pump and plug the hose to prevent water from siphoning into the engine". (then they say to put a tag in the ignition switch as reminder to hook it back up before restarting the engine)
It says to do this AFTER engine/water have been shut off, after flushing is all done. Given the boat is out of the water at this point, I don't see how any siphoning could possibly happen. Am I missing something? Do I really need to do this?
Looking down into the engine compartment, this hose seems pretty tough to reach - if I'm even looking at the right thing!
This is one of the new catalyzed EC engines, if that matters (5.0 MPI EC w/ Bravo3)
