atomic 4 shifting in forward-- heavy vibes
just bought my first atomic 4 and it was purchased thru an estate sale. so No previous owner to ask.
My problem is after just starting and engined warmed up, I go to put in forward and engine vibrates very strongly- boat will move slowly but mast shakes violently- i will then her back into neutral and maybe reverse and try again- sometimes she connects ok and other times it may take 5 or 6 times before she catches forward with no vibrations-- works fine in reverse though-
tried adjusting shifter
any suggestions-greatly appreciated
