Moving up to a bigger boat that has the B3 outdrive instead of the Alpha that I have today. Dealer is putting a flush kit on the boat, and he told me to pull the boat out of the water, hook up the hose and turn on the water, then start the engine and let it run for a few minutes to flush the engine.
With the flush on the Alpha, it was done out of the water, but was always done with the boat off. Does this sound right with the Bravo setup (I know the water pump isn't in the drive, so does that account for the difference)? Any problem with pushing SaltAway through the engine like this when it's running? Is the flush port on a Bravo just functionally equivalent to putting muffs on the drive? And finally, are there any concerns with this setup (like running the water before the engine is started, am I going to hurt anything)?
