Olson Boat Spring Operated Leveling Trim Tab Plate Set 8" x 4-11/16" Vintage 20hp MerCruiser GM 3

MerCruiser GM 3

just ask) This gear set will not work in a MC-1/Pre-alpha & R gearcase (I apologize for the redundancy of this statement)

Superseded to: 865328A01 (which was a newer one that was classified as Design-II and used on newer models 0M815639 & UP) - so Ideally you would be using this to replace one with the 816461 Stamping

but basically the uppers only came in 2 flavors and the lowers came in 5 flavors
