Switched over to this 2025 model for our guide boat. The mechanical shift and throttle hookups were straightforward and precise. We’ve put about 75 hours on it running through marsh creeks and open bays without a single glitch. Yamaha reliability speaks for itself.

I was looking for a modern, lightweight four-stroke that wouldn’t sit too heavy on the stern, and the F90 inline-4 platform hits the sweet spot. Out-of-the-hole acceleration is snappy, and it tops out right where I need it. Super reliable engine for coastal and inshore fishing.

The under-cowling layout on this generation is really clean, making routine checks and filter changes a breeze. It runs cool, pushes our skiff smoothly even with a full load of gear, and has zero hesitation when you throttle up. Great investment.

Pulls strong through the mid-range and has plenty of power to get on plane quickly, even in a chop. Very happy with the overall performance and how smoothly it integrates with standard gauges and mechanical rigging.

Repowered my bay boat with this 2025 Yamaha F90LB, and the difference is night and day. It’s remarkably quiet at idle, starts instantly, and the fuel efficiency has easily cut my weekend fuel costs in half. The 20-inch shaft was a direct fit for our transom. Fantastic motor!
