Need help finding part number for trim switch J50PLSNF

[hfdad]

I have a 2002 Johnson J50PLSNF on my pontoon boat. The problem I am having is that the trim switch on the throttle handle only works in one direction. I believe the switch needs replacing but can't find any part number for it. eBay sells conversion kits but because I don't have a part number, I'm afraid to order anything for fear it may not fit or work.
Any help is greatly appreciated.

Look on the accessories listing for a control like yours, on that year motor, on crowleymarine or equivalent. I had the same issue some years ago, and it was difficult to get the part number, but I eventually found it. Once I had the P/N, the replacement switch was easy to buy.

Here is one parts list for a control for your motor, Not sure if it is the right one. See part #69

There are other controls listed as well.

Are you sure it's not the relays?

Does it work with the switch on the lower cowling?

yes

I believe the switch needs replacing ?

have you actually digged into it to check if power is actually transferred or not to the control wire all the way back to the relay ?
.
Switches do go bad but they usually carry very little current and it may be perfectly good. Trim switches are usually momentary single pole (12v) double throw switches so just take a volt meter and confirm it is the switch that is bad or not....

if ok trace the faulty wire back to the motor.
see typical trim switch 3 wires B+red supply and 2 wires back to the relays

I have not put a voltmeter on it yet, but since the switch works in the up mode and once in a great while works in the down I assumed it was the switch. Good idea to check it though. Thanks.

the switch may be mechanically defective or the contacts pitted or.... any wire junction up to the parallel mating joint of the cowl switches may be oxydized loose whatever...
