Force Outboards 75-150 HP (15 splines) Identification

75-150 HP Force outboards with 15 splines are some of the hardest motors to prop. The reason being for this is that Force produced three different style outboards in this horsepower range.

The first style is called “Single Exhaust” and does not utilize thru-hub exhaust but has a snout that exhausts gasses instead. *We currently are not offering any "Single Exhaust" prop online due to a manufacturing issue.

The next version, “Dual Exhaust” keeps the snout, but also uses a thru-hub exhaust system as well.

Finally, is the thru-hub exhaust only model that uses a Mercury gearcase.

*Both the single and dual exhaust models have a slightly smaller gearcase than the thru-hub only model.

Many of these motors overlapped production years, so we can’t go by model year alone.

See the images below to identify what you have. The images are clickable links that will take you to the props that will fit either the dual exhaust or thru-hub only exhaust.
