Hello all,

Ok I have done some research regarding this and have tried all the troubleshooting technique, which are very good. Now here is a weird one. I noticed the trim tabs were not working and tested everything as posted. Motor runs up and down solenoid click on one side. I then pulled the unit and noticed the reservoir was empty. So I figured ok this is a easy one. I poured a about 1/2 quart in the reservoir and hooked everything back up. I tried the tab to have the system bleed itself and heard the motor working. I then noticed the reservoir was empty again. So I poured more ATF fluid again and it ran dry. So I figured it has to be going somewhere. I looked and looked nothing.

Then all of a sudden from the rear of the boat under the out drive where the bell housing meets the hull I see the ATF fluid dripping out.

Is this possible? does anyone know where the hoses are routed on a 252 Formula for the trim tabs.

The hose for the starboard side trim tab exit the motor then there is a fitting that goes behind the wall that the trim motor is mounted on. The port side runs along the back wall then exits the port side to the trim cylinder. I really hope there is a way to get to the hose as I think one maybe leaking or broken.

Thanks

Ayuh,... The line to the starboard tab, should be exactly like the line to the portside tab,...

Donno what "Wall" yer talkin' 'bout,...

That's odd. Sure you dont have a hole in the hose outside, that when you hit the switch the fluid is pumped out the hole under pressure and by coincidence is pointed towards the drive??
Fill it up and have someone watch from the rear

Can you see where the pipe nipple comes through the transom?



It's number 17, check the 90 degree elbow and nut and ferule fittings on it.

I will have to pull the actuator assembly off to see if that is where it is leaking. I probably have to remove them both. The leak is definitely happening on the inside part of the transom ("wall"). As I filled the reservoir and motioned the tabs up and down ( which did not move) the fluid was gone from the reservoir. So I filled them up again and noticed that it was seeping slightly from the drive to transom location. So I looked in the bilge to see if one of the line that I can see was leaking and they were fine. But down in the bilge area I saw some fluid. So it has to be in the area of 15, 17, possibly 18 on the actuator.

I am not sure if there is a hollow space between the outside transom and inside transom where the motor is mount to.

If there is on access to the inside of the transom, the actuators may have what we call pre-connected fittings:

I am not sure if the fitting I see is the back of the actuator or if it is a fitting. But it is not leaking on the inside fitting nor is it leaking on the outside, so it is in between these 2 areas on the transom.

I will have to double check tonight

Duh. Bell housing= inside. Got outside in my head when you said outdrive
Sorry bout dat!
