I would appreciate any help in determining what might be causing this problem.<br /><br />Twice in the past week my 1999 200 hp merc.tilted up to the trailering position all by it self. The first time was immediately after I cut on the battery switch. The second time was after I started the engine and was idling for about a minute. Both times I was able to get the engine to go down by pressing down on the T/T switch located on the engine. Pressing down on the T/T switch located on the trottle handle had no effect and the T/T motor continued to run even after the engine was all the way up.<br /><br />I suspect that it may be the T/T switch on the engine cowl(sp?) shorting internally, but I suppose it could also be the solenoid.<br /><br />Has anyone had this problem and what was the fix?<br /><br /><br />Thanks for your help..<br /><br />Ed
