[Rhodes22-list] Is there anyone out there who can help mewith my Yahmaha 9.9 4 stroke

[Mary Lou Troy]

What engine? Recent Yamahas have a port with a hose fitting allowing 
fresh water flushing with the engine off after every use. Very handy. 
I think newer Hondas have something similar but you have to remove 
the cowling to get to it. Our older Honda died from saltwater 
corrosion. I don't think it was an issue when we were based further 
north but the past few years we've done a lot of trips south of the 
Bay Bridge. The flushing port was a large factor in our decision to 
purchase the Yamaha. Because Fretless is in a slip all summer, the 
earmuff solution wasn't practical.
