I am a bit late on this thread but there is an emergency work around for the transmission solenoid failure, its on page 74 of the Volvo penta operators manual ( D4,D6) . It involves loosening a screw and removing a washer which locks the transmission in forward for emergency use . You must then stop the boat by shutting off the engine , but at least it can get you back to the marina for repairs.
We had the issue on our 2014 R29 leaving the dock at Bowen , we got back on dock using the thrusters fortunately and repaired the corroded connectors using crimp connectors .. .not elegant but it works. They require regular protection with dielectric grease. Its also not a bad idea to build a little shelf above the stuffing box to limit the salt water spray..
I'm a bit late too "nomasrata2e" and I don't see the emergency work around you site on page 74 of the owner's manual.
I think it is very important to share my experience. We e got the dreaded fault on our return from Olympia, "Check Shift Actuator" and needed to be towed back. We had no forward or reverse. We have a 2015 Cutwater 30 CB Volvo/Penta D6. What's even more concerning than this one failure to me was that the previous owner had the transmission replaced under warranty and the new transmission had the new sealed style that failed. So my replacement sealed solenoids are identical to the sealed ones that failed.
Only one of the solenoids went bad, but for some reason the other is linked causing both to stop functioning. Hence no forward or reverse even though only one was bad. I went ahead and had the technician replace both out of an abundance of caution. As you can see in the pics, although they are sealed, there still seems to be corrosion where the plastic seal joins the metal and a breakdown of the rubber collars where the leads go into the "sealed solenoid".
A rep at Pacific Power Group said because of the collars, "they might be suspicious for water intrusion".
OK, so like some have expressed concern in this thread, what if this failure happens in a tight situation, say rapid water at Deception Pass, or like the strong currents we get here in the Narrows. Or to Kevin Lamont's point, "One thing to think about with a shift issue, when there is a problem while underway if it doesn't cut throttle it could potentially stick in gear and have no way of slowing the boat down." That would cause a huge issue if it happens docking your boat and for other boats at the same marina.
Don't get lulled into a false sense of security that the new sealed solenoids are failure proof. I have a $2,000 repair bill to prove it can happen and an uneasy feeling about future faults!
I am interested in hearing from others.
