Honda BF75A gearshift problem
My 1999 model 4-stroke Honda BF75A developed gearshift problems last.season. Started with gear crunching while out fishing, so I limped home on auxiliary engine. I have renewed the Honda control unit in cabin, the gear cable and all external gear linkages and checked that the gearbox itself is ok. On this model the gear change is transferred from the external linkages outside the powerhead horizontally through the powerhead innards before a final internal linkage transfers the change downward to the gearbox. I can operate gear selection manually so I know all linkages are fine. I can set the gears fine in harbour, take her out on the water, run through some gear changes, and she performs fine for a short while, and then the gear crunching and gear jumping starts inexplicably again This problem starts when the powerhead reaches operating temperature , but why? Has anyone experienced this problem, and what did you do to resolve it?
Thanks
Don
