I called the dealer. He said to connect the hose at the flushing
attachment, but not to let the engine get over idle speed.



If the dealer said to use the flusher hose and fitting under the motor's
powerhead, I'd be having a word with that dealer person. The Yamaha owners
manual, service manual, and training seminars state specifically NOT to run
the motor using it. Only run the motor with the "earmuff" type flushers
around the gearcase, preferably the dual hose feed style muffs.

I had to buy the double sided muffs for the 115 - the single doesn't cut
it. The rectangular type seems to also work better than the round ones.
Don't know about the 90 - it's hasn't seen sal****er yet.
