What's the most likely problem ...
I have a 1999 Merc 2strk/3cyl 90hp (low hours/use) ... and the tilt/trim (tilt down) has been giving me a problem lately. Tilts UP just fine, but last time I tried it, it wouldn't tilt DOWN.
It's in storage, right now, so I'll not be fooling with it until March, but I'm just looking for the easiest & cheapest option to get it working again.
I've watched some DIY videos, and most point to the brushes being gunked up or worn down as the most likely culprit. It's not the battery, or connections from battery to switches (throttle or one on side of motor) since the motor will tilt UP ... and until just recently it would almost always tilt DOWN, though there were instances when I had to hit the tilt up button for a second & quickly hit the tilt down button before it would respond & tilt down.
I'm pretty sure I can remove & replace the motor part, but I'm a little uneasy about removing it and taking it apart & cleaning it, then putting it back on. Looks simple enough, but that's always a red flag to me
I could probably get a buddy of mine to do it, and that would likely be cheaper than the local marine mechanic shop. And I doubt they'd take it apart & clean it, anyway ... they're more into the yank off the old & put on a new part kinda operation.
I will take a meter and test the current flow, just to rule that part of the equation out. But, I'm just curious if anyone knows of any other things to look for, or check out, before I even think about starting on repairing it ??

Might also be that switch. Does it have more than one? Try another if you do. I have 4 on my boat. One on shifter, one on steering, one on motor housing and one at the bow. More places to have problems. lol

Swap the two relays or solenoids out and see if the problem reverses itself...if it does you have one thats bad. Its easy to do and a good way to check.

Yeah, and I saw on a video that the contacts can get corroded ... so removing the plug (male posts) ends and cleaning the posts is a possible fix.Originally Posted by "G"
