I can't identify this sensor on top of my IRM-40 transmission, 2005 SV211

[Carpenter]

My PCM IRM-40 transmission is leaking around what looks like n oil pressure sensor of some kind that has rotted out. In the exploded views I have seen and parts diagrams I have found in this location there is just a plug. Does anybody know what this is or where to find one?

That is a neutral switch. It is there to make sure the boat is in neutral for starting.

Nautique Parts and Discount Inboard Marine sell them.

Thanks for the info. I am new to this and to the boat. There seems to be a lot of great info out there but I am still getting the lay of the land.

No problem.

Could be just a bad O-ring on it. That’s a lot of rust there though. Especially on the terminals. If the switch were bad the boat wouldn’t fire up though
