Well since this last post I've learned a few things. I found the solenoid and I have isolated the problem to the pump cover housing or possibly one of the hydraulic hoses. I also learned that this is a design flaw with Volvo Penta. Unfortunately the part alone is a little over $500.00, which is redesigned part I guess they figured out the original design didn't work!! I've contacted Volvo Penta consumer affairs with no luck. They don't acknowledge this as a design flaw, a hydraulic fluid reservoir mounted on the outside of the boat submerged in water? Any how are there any easy fix suggestions out there other than buying the replacement part. Any help would be appreciated, thank you.
