Why is it called “90 HP” if it’s a jet outboard?

Jet models often use a 90 hp-class powerhead, but the jet pump output is typically lower than a prop-rated setup. The “90” denotes the model family/powerhead class, not necessarily pump output.

What kind of boat is this motor best for?

It’s ideal for shallow, rocky, or debris-filled waters where prop damage is a concern—commonly river boats, jon boats, and other shallow-draft hulls set up for jet operation (often with a 25-inch transom on X-long configurations).
