Well theres a few.. Maybe someone can tell me the exact ratio i have a 2.5-1 2-1 and 1.85 ish' -1
the 1.85 -1 has a belguim i.d. Tag.
As far as I know all the three cylinder, 15" midsection, 75hp engines, since the small gearcase came out in 1975 are all 15:28. Right through to the end of the SST-60.
But there could be two cylinder cases or gears in use under a triple.
Yep, it is a fishing case
Since 1925, about 150 different racing outboards have been made.
They are all "fishing gear cases" if that means they shift and have conventional through hub exhaust. The 15" 75hp models after 1975 all had a 3-3/8" diameter case with the 15:28 ratio and the 20" models all had a 4-1/8" diameter case with the 12:29 ratio.
The smaller case and the 15:28 ratio is very desirable if you are trying to go fast.
