Well guys, I have ANOTHER question!!!

[daselbee]

OK no brainer for those familiar with FasTrack TT systems.

I bought a complete TT system PN 5005115 to replace a defective unit on a 2004 E225FHLSOB.

This unit is the new replacement for many many models.

I am bench testing it. Chucked in vise vertically, battery is used by simply holding the blue and green wires on the terminals for desired direction.

OK. Unit goes UP fine, but when I reverse the power wires to make it go down, the tilt rod retracts fully, but the trim rods do not.
Tilt rod hits bottom, motor stalls, and current goes way up....like 70 amps or so.

Am I supposed to have the motor weight on this to allow the trim rods to go down?

On a 1996 model, when changing both the trim motor and the manual release valve, I tested it in just this same manner, and the rods went in and out no problem.

Has the design changed since 1996 and new ones don't work like that?

well. proof here that a factory service manual is invaluable.
It is right in the manual....when tilting down, the tilt rod pulls the engine down.
When the trim rams contact the thrust pads, the tilt rod action actually pulls the trim rams back to down position.
It is not actually the engine weight, but the downward travelling tilt rod that returns the trim rams to full down.

So they had a change from the older models?
Something doesn't feel right about the manual description you put up?

 

[daselbee]

I can quote it word for word....I thought for sure the trim rams go down by themselves.

Evinrude factory manual E225FHLSRM, manual part number 5005649.
Page 344, describing the operation of DOWN mode:

"When the swivel bracket contacts the top of the trim rods, the mechanical force of the tilt cylinder pulling the outboard down
also pushes the trim pistons down. Fluid is pulled from the reservoir to the top of the trim cylinders."

That description also makes sense when looking at the fluid flow diagrams.

????? Gotta assume it needs to be mounted to see trim rams go down.

With the older models if you tilt to the top then engage the support levers you can then retract the trim rams while the motor is still up.

I looked it up in the 1996 factory service manual.

Here it is section 9-3.


"Pushing the DOWN switch pumps fluid ONLY into the top of the tilt cylinder.
The engine tilts down, and trims in, pushing the trim cylinders in as it travels."

I have a working one down there now. I will compare it's operation tomorrow.

What has happened here is that the LU hit a caprock head off Key West at 40 mph, and in the distance it travelled dragging the skeg, it took about 3 inches off the bottom of the skeg.
The TT system doesn't work anymore, either up or down. The motor turns, but it sounds locked, as if it were all the way up or down...end of travel sound.
Something broke in one of the check valves, I think, due to the hard strike. Not sure yet.

So, new TT unit, and I was bench testing it (before spending a day beating out the pins) to make sure it was good, and the bench testing brought up this question.

Another win for OEM Manuals.
