"Chris, use the Seloc manual in the outhouse or for images only.... get yourself an OEM manual, or download the Volvo Penta .pdf version from online!
Chris, the coupling rod (the rod that pushes against the lock brace) can be eliminated, believe it or not! Often this will make REV engagment a little easier.
You are correct! With a drive fully DOWN, it will not raise by hand unless you reach under and manually release the mechanism from it's hold on the set pin!
If the lift-out unit is extended any, then lifting the drive by hand requires no manual releasing!
As for an adjustment..... well, there aren't too many to make here unless there has been some sort of wear or damage!
If the electric lift-out unit will not release the latch hooks......., then your lift unit "Pressure Plate" is not pushing the latch release rod down enough.
This is usually not an issue with the pressure plate, but rather an issue with the rod itself.............. OR the thrust sleeve at the top of the rod!!!!
The pressure plate must FIRST depress the sleeve/rod enough for the rod "travel" to release the "latch hooks" from the set pin.
If not, then raise the thrust sleeve up some and re-lock the jam nut.
Conversely, when a drive is to be locked down, the vice rod (and pressure plate) must be fully retracted (amber light at the helm goes out) giving reasonable space between Pressure Plate and the thrust sleeve.
The thrust sleeve and push rod must also return to allow for a "locked position".
Sort of a summary here:
**Latch hooks must have crisp sharp tips
**set pin in good condition
**transom shield set pin ears in tact
**the single return spring in tact
**push rod/thrust sleeve free to move up/down within the suspension fork arm (this is a common issue)
**no corrosion restricting any movement of mechanism (another common issue)
**Vice Rod fully operational (if bent, it will cause issues)
A good working lift-out unit will allow you (with a fair amount of force) to push a raised drive down by hand!
This indicates that the internal clutch is working!
If you cannot push it down, then the spring pressure is too great.
If it goes down too easily, then more spring pressure is required.
