Evinrude 40 hp power trim why does it not engage from shifter handel or on up down buttons on engine?

Hi. Uncertain if you own a runabout or a larger boat but this might help. Because you have tried both control positions for the trim adjust, I suspect the trouble lies with 1. power to hydraulic pump (or electric ratchet motor if so equipped)
2. frozen, corroded or stuck trim plates or transom mount swivel points.
3. Check for correct levels of hydraulic fluid in system or test for correct voltage to ratchet motor(s) if this is the system used. Use a jumper cable to directly power the motors or activators if low, or irregular voltage found. Test again.
4. Any obstruction or debris deposition at or near the working parts.
Finally, a local marine mechanic will tell you what is wrong and the cost to fix.
Hope this helps.

Have evinrude 225 etec and the hydraulic tilt will not tilt motor all the way up

Hey Hunter,
First, make sure the manual release screw is seated tight.(port side of engine mount) ..Does the pump run and just not lift? Does the motor jump and jerk while you are trying to trim up? Can you lift the engine by hand while you are trimming? Have you filled the fluid reservoir with fluid? - There is a cap with a slot on the reservoir - MAKE SURE the engine if at full tilt - fill the reservoir.. you can use Dexron type III transmission fluid.... check these items and reply to me.

My 1978 140 evinrude electric trim tilt motor working but wont lift or lower happend suddenly after it lifted.maybe the pump?

First make sure you are not in transit mode. Some outboards have a lever which keeps the motor tilted for trailering. You should have a fuse for the tilt motor, check that. If the pump is turning and it sounds like it is whining you are pushing air and either lost your hydraulic fluid or have an air bubble in the system. Check your fluid reservoir.

Where do i put in hydraulic fluid in a johnson 225 boat motor

if its an outboard you will see a reservoir near the cylinder on back, be careful and set the shallow drive lever so the weight is off the hydros when you open it, there can be up to 3000psi if it has weight/pressure on it

once added you have to blead air bubbles, go up then down at least 10 times

also a boat parts store(phone book) may be able to help you
