Re: Selecting an Outboard
I/O in salt if new, needs the closed cooling system, but this just covers the block, the manifolds and lower unit are still seawater cooled.. what some do, if available at the dock. install the flush muffs lower the lower unit, turn the fresh water on and idle for a while, to flush out the system. then raise the lower unit, and leave the muffs on, with the hose attached, to help prevent seawater from entering. it's not perfect but better than nothing. also a 200 hp weight so much even when tilted most lowers are still partially in the water.
