I believe they use compression fitttings on the tubing. If I remember
correctly they had those little brass inserts that went inside the
tubing as well as the brass collar that compressed. You may be able to
just get a fitting to splice the cut tube from lowes. I believe the
fitting that went through the transom was pipe thread where it connects
to the hydralic cylinders on the outside and can be unscrewed form the
inside. I put atf fluid in mine. Power steering fluid probably works
as well as any other light oil.

You do need to make sure that you don't apply power to both directions
at once. The motor seems to have independent windings for forward and
reverse rather than actually reversing the polarity. If you have to
experiment with the switch to figure out which wire goes where keep
that in mind.

The motor goes slower in reverse. I presume so that the retract speed
is about the same as the extend speed. Mine takes about 8 seconds to
go fully in either direction. There is no load shutoff or pressure
relief on mine so it will stall or come close to stalling at full
extension and full retraction. I try not to do that too long as I
figure it can't be good for it.

It is a bennett, I was able to trace all the wires and tubes. Its does
not look to be hooked up. 2 hoses come off the pump, one goes to the
port side stern to a 90 degree nipple inside of stern, matches to out
side of port trim arm. Other tube is cut and has a nice little spider
nest in it guess I need to hook this up first then switch and
power. Any tips I need to know before I start?

Thanks to all the posters again, has been very helpful!
