No neutral. Neutral selected but boat keeps moving FWD

[Marcelo Sanabria]

Hi Tony!

Last week, my Port side Cummins QSM11 with Twin disc transmission (MG5082 SC) with manual shifters, started to fail. Even with the lever in NEUTRAL, the shaft is rotating as if it was placed in forward but at a lower speed than if engaged to the FWD position, it also generates a little thrust. (See video attached)

Cable is OK. Oil was replaced 3 months ago. Temp and pressure look good. Reverse works well. Mechanic told me that it is time to service the transmission cause warped clutch plates, worn seal rings, etc. My question is: Will it make more harm to other parts if I run the boat like that for a couple times or for the season before replacing the needed parts?

Tks in advance

Marcelo

Hello Tony!

Thank you very much for your reply,  your input gave me a lot of mind peace.

But also, FYI and feed back for the forum, I checked the oil level again and it was a little low, so I added less that a quart and guess what… The transmission worked just fine.

Have a great summer and thanks for your precious tips.

NO harm using the gear until you have the time & $$ to deal with it.. Even using it for muliple seasons will not matter as long as it it  dragging in fwd, not reverse and you still have safe control of the vessel.

The issue will be very expensive to fix (R&R) and the  “fix” may of may not solve the issue depending on the experience of the mechanic doing the work.
