Default Problem with gear shift 2015 df 300 ap

Boat was run last around July 4th Its been on lift. I wanted to test it today before fishing friday. I backed out of lift and it wouldnt shift into forward even in neutral it thought it was still in reverse. That makes me feel the problem is in neutral safety switch and not engine. The actuator is supposed to have a fuse but I havent figured out yet where that is. So I shut it off and we drifted back toward lift and I started it and this time it went from forward into reverse just fine. Decided with my sea tow all paid up we would go for a ride but 100 yards from the dock and it got stuck in forward this time even when shifted to neutral so a made a quik turn and headed back to the lift. a second problem I have my second c10 gauge in five years just failed. I have the district suzuki manager promising me he will get me a new gauge at dealer cost but he didnt call back today as promised. so I had an alarm but cant see what code. Alarm stops when it starts working properly and comes back on when it gets stuck. actuator seem to be working fine visually when there is no alarm..

So how do you get shifter apart I see small machine screw in back of handle and larger one on top OK I figured that out, nothing serviceable in there except now I know how to adjust throttle tension.

If your C10 was working, I think you would see this


This is the page from the service manual



My DF300 has been getting this shift issue intermittently. My white wire is connected to my battery switch. I've learned that by shutting the engine off and cycling the battery switch back to off, then to on. This resets the system. Usually, after the first reset, my engine runs perfectly the rest of the day. On occasion, I've had to do multiple resets when first getting under way.
At my next service interval, I will investigate things in more detail. What I have read so far is this sensor is adjacent to the shift linkage on the right side of the block. There is some adjustment possible but to get the voltage just right requires a dealer's special wire harness.
My plan is to gain access then thoroughly clean and lube the shift linkage to ensure full throw. Check to see if this sensor has loosened or worn. Finally, make some blind adjustments ( my alarm only happens in forward gear). I think if the sensor was bad, then this issue would repeat every shift.
Please, if you get it sorted, send me a PM of your fix.

Ok I tracked down a new mobile mechanic who is some kind of master Suzuki mechanic. I have him coming next week. He said he knows exactly whats wrong. He even carries the parts in his truck at all times. It turns out there are two bushings in the actuator that when worn start to stick. When they stick the full the computer into setting off the alarm and locking down. When you turn the motor off and it sits it gets unstuck and starts again. He said he cleans the actuator and replaces the bushings they are good as new.
