I’m on my second Maxxum 101 and have had problems with the Maxxum pro bow mount yoke (broke an arm) nothing with the board.
The biggest problem I have is getting parts as a few parts have been discontinued and it seems that all inventory has been purchased.
I have tried motorguide (101) and had problems with the board (I think you may have something Tom).
All that being said I would be interested in purchasing the Maxxum pro bow mount or just the yoke gas assist part
