I have a 1999 throttle/shifter on my merc. 90 h.p. 2 stroke. It has now been 4 years and the shifter it loose, ugly, and the trim switch sticks. I have tightened it up with the allen wrench fititng several times but it is starting to do less and less. It still wiggles. Is there a replacement/ upgrade version that will fit. Has anyone had the same troubles?

Locktight on the allen screws and some wd40 on the trim switch should get ya going.

If you use Loc-Tite might I suggest using blue and not red. Blue can be removed later if needed while red is for permanent applications and a real bear to remove.

Sprayed some 656... trim still sticks. I worked it in real well and it feels like the spring is worn out.

After I bought a 1976 Mercury 50-HP engine, I noticed the throttle/shift remote control was not working smoothly. I disassembled it and found very little grease left unhardened and some aluminum chips (spalling) that had been ground off the cam portion of the levers.

I repaired the areas which had been damaged by lightly sanding them back to a smooth surface. Then I clean out all of the old grease and replaced it with fresh grease. It has worked well since.

I too have a 99 Merc and my trim switch gave up last year. I bypassed it with a mom on/off/mom on toggle switch on the dash.

Merc makes great motors but their controls leave a little to be desired.

I noticed they started to put better shifters a year or 2 after. How do those work, and would it be wise to put one of those in to replace mine

I have Mercury OEM dual engine controls on both of my Whalers, since 86 and 89. Not one single problem on any of the four controls, and thousands of hours of boating. They are not, however, as smooth an operating unit as the Yamaha control.

I have seen many re-powering jobs in FL where the Yamaha's were replaced with Mercurys, but the owner opted to keep the excellent Yamaha controls, which evidently work on Mercs also.

Ihg, thanks for info about the Yamaha control. I realized how poorly constructed mine was after driving my friend boat with a Yamaha, that sounds like the way to go.
