Im having issues with our shifter/throttle control on our boat. Last year it started not going into neutral allowing to rev up the engine. The father in law ( owner ) messed with it to try and free up the neutral button, now the shifter wont engage into reverse and while in forward the lever doesnt push as far forward as it used to before it was messed with. My two questions are
1- is the control rebuildable
2- if replacing which model would i need to replace it with?
Mercury OB332254
