Power Trim not working

I put my freshly charged battery on the boat today and when i tried the PTT the motor runs ok but no motion up or down.

The engine is an early 90s Yamaha 60.

any suggestions gratefully received

Cheers

Paul.

Hydraulic leak or has someone opened up the bypass valve to manually tilt the motor and not closed it?

if so , as mentioned. check oil level, its an obvious large headed slotted screw , size of a 5 pence coin, take it out and check level for starters

Have a look at the red arror. this is NOT a yam but its in a similar position...its on the offside of the engine mount on the outside of the hull , there is a hole. have a look inside, so standing at the back looking forward. look on the right side of the mount, the part that is against the hull...you will need a large left handed screwdriver . im sure its clockwise to undo. anyway try it, once undone 4-5 turns, then lift the engine up.the more you undo it the easier it is, this will expose the oil filler screw once up. you could try lift it up manually and down again a few times as maybe a air lock. then tighten the screw (not overtighten) and press trim and tilt button see if it works

RIBase
If PTT oil level is fine, the next step is solenoids. The carbon brushes within the motor do wear so it could be this, plus last, but by no means least, it could be dodgy wiring. A break or corroded wiring is enough to stop it working. A cheap multimeter is essential for fault finding.
