Came home to a shifter (others had used boat) stuck in forward on my 2002 40hp merc ELPTO on my pontoon. Of course (I was told they did nothing wrong to cause this) and it won't start in gear. I am hoping someone can give me a sequence of what to check first. I have recently replaced the impeller but ran it several times after that with no problems. Shift linkage was reconnected in the same spot it was before. Should I start by removing the lower unit, or could this be a cable problem?
