A problem developed today with my engine. It won't go into neutral or reverse. If I pull the lever towards me (reverse) it still goes forward and accelerates. Is this a shift link problem? Any ideas?

I had a recall on this motor when I first got it in 2000-- to replace the shift link. The problem was described in Mercury Marine Service Bulletin 2000-4 (which I do not have). I did have the recall work done.

Anyone here ever have a similar problem? Suggestions?

I have a month left on the season here and am thinking about using the motor as is (primarily for trolling) here on the lake and then have it serviced. Any thoughts?

Additional comment: When I start the motor, it is in already in forward, not neutral.

I suspect that the shift cable has come loose in the control box. Detach the shift cable at the engine, move the control lever and see if the cable moves. If it doesn't the problem is in the control box.

I guess you mean 4 stroke 4 cylinder. I have a 90 4S and also had the factory fix done. Your problem seems more major. The neutral start safety switch is in the shift control. The wire runs from motor to shift to key. Like Dick said, chech the cable ends, but also in the motor. The lower cable in the motor is for shift, upper is throttle. I hope that would be your fix. I would not use it as is. Your reverse and neutral are your "brakes", and it is a major safety issue.

Good luck,

Brian K.

Bad News: THe problem is in the engine itself.

More Bad News: The warranty expired a month ago.

Good News: The problem is with the shift link assembly, and was subject to a recall in 2000. I had the necessary warranty work done in late September 2000.

More good news: A colorable argument can be made that the warranty on the replaced part is still running. In any event, the fact that the problem was subject to a recall is of significance in dealing with Mercury.

My local boatyard has been working with an authorized Mercury Dealer on this; I am moving the Montauk there next weekend. We are faily confident Mercury will cover the cost of repair.

It was the shift link assembly; Mercury covered the cost of the repair.
