Need to look at page 1c of the Mercruiser 14 service manual. It can't be the fuse since the motor runs in the down mode. If you need to transport the boat and must raise the drive, take the plastic covers and nuts off the trim cylinder stern ends to free the drive from the cylinders, lift the drive and strap it up with line or nylon straps.

Alternatively, there's only a few more steps involved to pull the drive off the bellhousing now that the trim cylinders are loose sure makes lubing the coupler a breeze One quick thing to try - check the level of the hydraulic fluid in the unit.

We had a similar issue the switches were working as we could hear the pump trying to raise it in our case and found the level to be down. Filling it fixed the problem. Our theory is that while lowering, gravity is helping, so the low level of fluid was still sufficient. But to raise it, there just wasn't enough push. Good luck! Any Luck? Wiring diagram for the boat won't help. The link I posted above has a diagram for Mercruiser drives.

Same Problem But Easy Fix. Propped up the stern for the winter in the rack and many thoughts incuding failed pump, low fluid etc over the winter. Simple problem Corrosion was the culprit. Simple 5 min. One should be green and the other blue. You will probably be able to find a quick disconnect plug near where the wires exit the outboard engine cover that you can disconnect.

The Trim Sender Switch is used to send a signal to the Trim Gauge so you can see the level of the drive. The Trim Limit Switch is a safety device which keeps the driver from over- trimming while under way.

Trimming the drive too high while under way can cause damage, injury or death. How do you troubleshoot a trim gauge on a boat? The Trim Gauge can be tested by: Disconnect the 4-wire harness connection. Power the gauge by connecting 12 vdc positive to the gray wire and a good ground to the black wire with gray stripe. Have no other wires connected to the gauge. The pointer will slowly move towards the "Up" end of the scale.

How does the trim gauge work on a boat? A boat's trim gauge monitors the position of the drive or outboard. Make sure it's accurately adjusted.
