This is the 48 spl on the 15 footer i bought. The big one on the Winner 1850 is totally different.
When I bought the boat it had the tilt assist removed and tilt was permanently set with a wood block.
Bought a used power tilt/trim assy. And started fitting it up.
First challenge was the upper pin was gone. A $40 pin. So I got out the dial calipers and found a 5 inch 5/8 bolt will fit perfectly and allow a nut and lock washer. The bolt head clearance is close so I may trim it down a 1/4 inch or so.
The bottom rod is 1/2 20 thread on the ends and a quick cleanup of threads was all that was needed for it after "tapping" it out of the frame.
The unit I bought clearly has the 397532 part number on it. However it looks nothing like the drawings on any site I've found. For one the fill is on the end of the unit between the unit and the motor bracket. Not on the back. Guessing early versions were either filled and bled on the bench or the frame had an access hole.
Also I have completed designing a control circuit that eliminates the need for hunting down internal brackets and harnesses.
I found a crack on the electrical motor at one of the motor screws. So I've got a new motor on the way.
Meanwhile I've got the cylinder on the bench learning more about it's internal workings. Found I can effectively bleed it there by uisng a 3/16 socket on the pump drive shaft and a cordless drill. It runs slower due to the rpms. after a few cycles i had bled all the air bubbles from the cylinder. They end up in the pump reservoir and slowly dissipate.
Based on the fill hole location these are designed to have air in the top of the reservoir and the high speed spinning of the shaft will cause some foaming. I mention this mainly because initially I thought I had water in the system due to the pinkish color of the fluid when drained. but after the old fluid set in a container it returned to clear.
The other item I found was a black plastic piece that sits around the pump with a strainer. It has a second white plastic piece on top of it. Both have seal which when assembled force the pump to draw fluid through fine mesh screens. Can't find these in any parts drawings I've seen. So I don't know if they were later eliminated or what? The concept of filtering makes since but the size of the screens could restrict flow to the pump.
