This year must be our problem year with the 84. Today we were cruising down the lake (maybe 25-30mph) and all the sudden lost all propulsion like the engine suddenly lost contact with the transmission. No sounds. Stopped, turned off and on and even tried manually pushing where the cable hooks to the transmission as it was almost like it just wasn't shifting into gear. Still nothing. Revved and the shaft stayed still, no odd noises, checked tranny fluid, it was a little low but nothing terrible. Added some and that didn't do anything. Any ideas? Damper plate? Tranny rebuild?
