The trim limit and trim sending switches usually fail from water intrusion and rust. If yours just went (1990) you were very lucky. You can buy new ones for about $75 to $85 on eBay, ussually someone has a set for sale.Replacement requires removal of outdrive. For the hassle and price (particulary retail price) most don't replace after boat exceeds 10 years or so...but I like to have the trim guage working because I'm always in shallow water docking and mooring.Port side should be limit switch, starboard, trim sending.
