Post Mud Buddy HDR - Problems in Reverse
I'm wondering if anyone else has had problems with an HDR that feels and sounds like it's slipping when in reverse even with a brand new prop. I'd compare it to having a spun prop on an outboard where it feels fine at low RPMs but when I add a little throttle, the engine revs up seemingly under no load with no apparent increase at the prop. Additionally, and I'll assume that they're related, I've noticed that some of the stainless steel pins/studs that hold the reverse magnets in place are backing out out the clutch cover with one of the pins falling out completely (See attached photo). These studs are just pressed into the clutch cover but I don't see what could be hitting them to push them out.
Sorry if I'm missing something obvious but thanks in advance for any help.

have you checked that your magnets are working? Check gear oil in trans.?

Yes sir. I checked and changed the transmission oil and also checked the magnets. I saw that one of the connections to a magnet was questionable so, hoping I'd found the problem, I redid that connection and tested the magnets with 12V to confirm that all three were working. I wasn't overly impressed with the strength of each magnet, but I'm not sure how hard they are supposed to pull so maybe it was normal. Afterwards, I ran the boat again and had the same problem with slipping or loss of reverse. Back at the dock I noticed that another of the magnet pins had backed out completely so it doesn't look like I've addressed whatever is wrong.

Thank you very much for the reply and thanks in advance for any other suggestions that you may have.

For reference, the attached picture shows the magnets mentioned in the previous posts.
