Trim Sender Sensor Sending Unit Fit for Volvo Penta SX DP-S DP-SM Drive, 3849411, 3855535, 3863007, 3849413

I would recommend this to anyone

This for a cheaper aftermarket option was good the complaints i have is the terminal ends fell off and needed new ones. And the sensor dose not adjust far enough to show down all the way on the gauge. Reading the resistance of the sender should go to 0 or close to it and this one only goes to about 13 which shows in the middle of down and quarter down on the gauge. Shown in pictures. Other than that works fine. Up on my gauge is all the way up on the outdrive.

The media could not be loaded.  Buyer beware. This product is not made for a boat. From what I've read, a boat trim sender (nearly all makes and models) have a resistance from 0 to around 175 ohms. So that means that when the drive is all the way down, the trim sender is sending 0 ohms. When the drive is lifted upward, the ohms increase. So one would expect that half tilt would put out roughly 80-90 ohms. Well, at about 1/8 tilt, this thing is sending all 175 ohms and making my gauge read that the drive is all the way trimmed up.I checked the total resistance on this thing, it went from 0 to 1,170. Wow. Horrible piece of Chinese junk. Do not buy. Thankfully, before I messed with trying to pull in this new wire through my transom (engine still installed) I tested it. I'm sending it back and ordering a different type with better reviews.

Worked perfect replacement on 2001 Gaston Sx

Got this to replace my Volvo Penta Duoprop sending unit. Got it installed and it signals completely in reverse. I tried switching wires around to no avail. So when I actually have the trim all the way down, it signals all the way up, and vice versa. It simply depends on whether the unit, when at the down position increases ohms from there or decreases from that position. If it was on the opposite side of my drive, it'd be fine, but there only one location it can go. Don't get for Volve Penta DPS with Faria Four Winn's trim gauge.
