Aftermarket trim gauge? 2002 90 hp

Hi all. I have a 2002 Mercury 90 ELPTO. I would like to add a trim gauge but a mercury mechanic told me that this motor doesn't have the sending unit. Is there an after market gauge that would work without a sending unit? Maybe some sort of universal trim gauge? How would I install one if it is possible with this motor.

Thanks

The motor does have a factory sender and gauge that is available at the dealer. I do not have the part # in front of me. I will find it.

Thanks for the fast reply. I guess he's not the sharpest mechanic. I don't even know where to find the sending unit. I looked all around the power trim motor and cylinder. I know it will be easy to install. Once I find the sending unit it should just be simple wiring and a gauge install.
I'll look for your reply.

If I'm not mistaken the sender will have to be installed along with the gauge. Just give timebandit awhile and he will find the part number for you, or call a merc dealer for parts and pricing.

Ok, the Merc part # for the sensor is 821400A05. (STBD mount in-line engine). (Not the V-6 one.) The gauge can be any Teleflex or whater kind you want. (As long at it says it fits Mercs.) Merc does not offer a "kit" anymore. They use to.

Thanks for the help guys.
Timebandit,
If I understand you correctly, I have to add the trim position sensor (the part number you provided me). Is this why I don't find a sender or some sort of position sensor near the trim cylinder?

Correct. That is not factory installed on 90's and 115's in those in those years. There is a mount on the stbd side above the ram, that looks like a BF slot screw where the cross pin goes through.

Get some auto anti-seize paste for the screws, or be kicking yourself in 3 years when it goes bad and the screws bust. The sensor does not last that long. :(

The way you adjust it by putting a rod through the highest pin hole (3/8 rachet extension) and moving the sensor to 3/4 line on the gauge with motor in that spot.
