2010 Merc 115 4 stroke issue when going into neutral

[pikie]

I'm trying to help my friend out with his boat. Its a 2020 115 HP 4 stroke, Model # 1115F13ED, Serial 1B816087.

Problem: Stalling about half the time when going from forward into neutral. It starts right back up, but when in current or wind, he often hits the dock awkwardly, not being able to throw it in reverse. This is after running, so the motor is warm.

I was able to view the motor finally and get more info. Before this issue, he pinned the motor on a rock, I believe at a dock, not when the motor was running. Had to trim up all the way to get off and it popped the rubber grommet out of the lower cowl. Once out of trouble, he said the motor did rev high until he could get the motor trimmed back down and popped the grommet back in.

Currently the grommet pops out when trimmed up all the way and turned all the way to one side. I've asked him to try and take note of which way his wheel is turned when the stalling happens to see if there is a pattern there.

I've researched the grommet part diagram, and don't see any retaining brackets for the grommet. Anyone familiar with this motor/part? I've got honda's and they have a metal retainer inside of the similar grommet. I did not see any visible damage, but I also did not take the grommet off since the boat was in the water still. I'm wondering if the looseness is causing tension on the throttle and there is a safety switch saying the motor is at too high an RPM to go safely into neutral so it kills it?

He lives a few hrs away, so it will be a while till I can work on it with him directly.

I've included a picture of the grommet half popped out.

Thank you

On mine, which is an 02, the grommet is simply he'd in by castings in the cowling, held in by tension until the cowling is removed. Easy to rip out with enough force.

For the stalling, there is a sensor that momentarily revs down the engine when going in or out of gear, to keep it from shifting too hard. One guess is that the sensor could be faulty or broken. I don't know if there's an adjustment or not. There is also a retaining mechanism that holds the throttle and shift cables in place, if enough force was exerted during the trimming up to rip the grommet out, it could easily have broken the hold down for the cables. An out of place throttle cable could cause this condition. I would start by looking in there for broken pieces, and making sure that everything sits where it normally should, and go from there.
