The OE OMC ones are probably NLA (no longer available). The newer FW boats that have Volvo power all seem to come with the same Teleflex CH 1700 but with a Volvo sticker on it. I would take a good look on how its attached to the side panel. That's the biggest challenge, getting the old unit in and out. The part that can be confusing, but is explained pretty well in the instructions is this:
The Teleflex unit is adapable to OMC, Merc or Volvo engines, I/O or outboard. So there are more different positions that the cables can be mounted in. So you have to know the following:
Does the cable push, or pull the advance the throttle
Does it push or pull to shift the unit into forward gear
The instructions I have for the one I bought (got it last year but did not install it yet, had to fix other things, old control still OK but probably doing it next fall) tell you this:
Volvo I/O:
Pulls to open throttle
Pushes for fwd shift
This determines which hole you attach the cables to.
You may have to make the hole in the backing panel bigger (post a pic of your interior panel then we can tell you more). Sometimes you can remove the control without having to remove the whole panel which on some boats is a trial. As in, you remove the shift lever. Then disconnect the throttle and shift cables at the engine. See if you can remove the screws that hold the unit to the inside panel. Then you are looking to find the connections for the neutral safety switch and the trim switch, these have to be unplugged before removing the shift unit. The idea is to have someone hold onto the cable ends, and guide them out while you slide the shifter unit out through the side panel if it has an open area large enough to do so, or if it opens up into the engine compartment. Look where the cables go from the engine to the side panel to see how its set up. Each boat is different.
You may be able to use it for the season the way it is, but I'd count on getting a better unit sooner than later....
is your OE one like this, if so they might still be available:
