Merc lower unit gears

[sparkbr]

Does anyone know of any sort of cross reference chart as to what gear sets will fit what lower unit for Mercury product? I have a 60hp merc with a bad lower unit that I'm having trouble finding the correct gears for. I'm sure there are other ratios available for this housing, especially with it being an odd ratio (1.62:1) but I cannot find the information or part numbers anywhere.

Thanks,
Brad

I was wrong, the ratio is 1.64:1. it's a 1997 mariner, 60ELHPTO, serial 0G495557. 14 tooth pinion with 23 tooth drive and reverse gears







Uses the newer style lower unit that bolts up from underneath

Too new for me,sorry.I saw the gears you have & I never heard of a 1.64:1.Most of the newer motors are 2 : 1 ??

Well, I found a complete lower unit at a reasonable price ($400) finally... If anyone is in need of parts, I now have a good lower unit housing, prop shaft, and driveshaft. All are from a 1997 mariner 60hp, ELHPTO, 20" transom. I know of some other models they fit, but not certain of all.

Thanks everyone for all the info,
Brad
