Re: BS, or anyone, Power tilt problem
Internal leak. *There is a bad valve or seal in the pump that is allowing fluid to leak back into the reservoir. *Nothing too horrible, but it will require a rebuild of the pump. *Feeling handy?
For us Volvo guys, there is a valve housing that would have to be replaced. *Throw on some new o-rings and you should be good as new. *The pump itself rarely wears out.
I don't know where to find microfilms for the Yamahas, so I can't tell you exactly what you need to do.
