After searching the internet for a week, I found the trim toggle switch I needed at the local Johnson repair shop. The young lady working the part counter knew exactly what I was looking for and produced the part/kit in minutes. The part number is 0176532, OMC, KIT AY, TRIM, SW BIN in case anyone else ever needs a replacement that is an exact fit for the motor, etc. mentioned above. I installed the switch this afternoon and so far so good. The trim is holding and not running down on it's own. Thanks for all the advice and responses to my posts.
