Last week I put my 23 walkaround with twin 1992 200 Yamahas in at the local DNR ramp.

As I was the only one there and there are three ramps I started the engines to let them warm up while I parked the truck.
As I was walking down the dock after parking the truck I noticed the port engine start to rise out of the water. I ran to the boat and turned off the engine just as the prop cleared the water. Just the thought of what might have happened if the tilt had kicked on a few minute earlier scares me to death.

The tilt switch on the throttle that controls both engines would not bring it down, The port control switch on the helm would not bring it down. The switch on the engine itself brought it down.

I fired up the engine and watched it for a little bit. Nothing happened. So I cast off.

20 feet from the dock the port engine came up. I had to kill it and go back to the engine and run it down with the switch. The bad thing is that with the one engine all the way up you cannot steer the other.

I unplugged the switch inside the engine and all is well.

6992,
i had a same issue with my 2006 150 4-Stroke Yamahas.
One day with maybe 30 houres on the ticker one motor came up by it self as yours. Switching uo/down many times the trimswitch for the single engines un the bottom of the binnacle control everything turned normal.
But now the switch won't work anymore nor he is doing any "click". It seems that the switch got some wather and sticked first temprarely and now forever. I will have it replaced under warranty.
In your case it will be the same problem, check well wich switch it is and order a new one.......

best regards

Chris

With some care and skill, it is possible to completely disassemble the cowling tilt switch on a Yamaha. You can clean and burnish the actual contacts, and reassemble the switch.

Failure of the switch in the UP position also happened to me. Water probably entered the switch and caused some corrosion and malfunction of the contacts.

I am spending the next 5 days on the river maybe I will pull the switch out and see what it looks like. I would rather not pay for a new one.
Once I get it out I may come back for some cleaning hints.

Thanks for the suggestion.

I just had something like this happen while on a Whaler trip to the 1000 Islands. I was having coffee in my tent and noticed my starboard engine was tilted up, upon checking it out the "up" relay was shorted. Found by pulling off each switch wire until I could identify the relay, and pulled off the blue wire, this allowed use at a certain level for the rest of the trip. When I put boat on trailer I had to touch the wire to relay again until motor raised for trailering. I was lucky because the tilt motor ran a long time on for 26 seconds and then off for 9 seconds after motor thermo overload tripped, a nearby camper heard it for a long time but couldn't figure out where it was coming from, next morning battery was totally dead!...Jack
