I took mine apart, cleaned out the contacts of all the rust and debri that was in there, and sanded down the contacts.
Sprayed them down with fluid film and then anerobic sealed the O-rings to the case.
That should protect them from further corrosion.
Even after doing all that my trim sensor only works for a small duration of travel and pretty much flicks from down to up in an instant, normal from what I understand.
Hardly!!! When I can, I buy engine parts from GM. Just replaced the trim pump reservoir. Went to Parker-Oildyne for that, and saved over $150 on Merc's rip-off price!
What we're talking is not about 'doing it the Mercury way', we are talking about doing it right, the first time, and in such a way as to end up with a job that will last the distance... Not some half-assed, dreamed-up, cobbled together with bits of tape and fencing wire, back-yard botch....
EOD....

not normal, i service boats that have old senders and they work perfectly fine, its a matter of wear not old quality
you seem to contradict yourself, you went through all the time and trouble to "repair" your trim sender and it still does not function properly while telling people who are familiar with the system and know the proper repair procedure they don't know what they are doing
...But you do it your way and i'll do it mine(saving money in the process).
My senders worked as per merc(apparently for old senders which is what i'm told from this site they are just innaccuate)
this website is NOT mercury, not sponsored or endorsed by, has nothing to do with them - it is a public forum, anybody is allowed to post here as long as they keep things civil
if you really must know, mercruiser's stance on the accuracy of the guage falls into the fact that they don't make the guage, they make the sending unit - the sender is adjusted to read correctly with the drive in the full down position, thats it and all
as far as the guage reading full up, halfway, etc... mercruiser has no way of judging the resistance values of the guage - hence the innaccuracy statements, here, on this site - not mercruiser, mercury, brunswick or otherwise
sorry if i offended you by saying you said people didn't know what they were doing, i see that you did not
