Need some help, please. I have a Johnson 2005 90hp 2 stroke, Model #J90PLSOA. I have a bad Port Temp Switch, Part#0585023. I thought I would just order a new part to replace but it seems the part is obsolete and no replacement part listed. I have check all over the net and can't seem to locate that part new or used. Anyone else ever need that part and where did you get it or any suggestions where I can find one?
