Default Mercruiser TRS drive electric shifting

Hey all. I have a Mercruiser TRS 330, and it has an electric shift motor/actuator. I'm pretty stumped on how what to replace it with, as I can't seem to find the original part anywhere, unless maybe used. But, I would rather replace it with something new. So, I was hoping someone on here would have an idea of what to do?! Thank you in advance for your responses!

You need to find one of these, you have a better change of finding the manual shifting brackets on a transmission someone is selling.https://www.mercruiserparts.com/bam/.../31588/988/290

That looks like the mechanical parts of what I have no?! I'm actually looking for the electric motor itself. I could totally be misunderstanding this entirely please feel free to correct me! Thanks!

Thank you tom! However, at this point, I'm hoping for a new electric motor. But, I will certainly keep your used one in mind!

You don’t want to use the electric motor. When they start to fail the only engage partially and burn up the transmission. Throw it in the garbage and hunt down a manual shift kit. Like said previously your best change is to find a transmission with the manual shift on it.

Most likely the switch in motor actuator. Mercruiser sells a replacement kit retrofit the old shift motor. It's needs bit more work though as the design oscillates. Try using a small value resistance in series with the circuit.
a stepper motor with optical interrupts would be a modern solution.
