Description

OPTIMAL FUEL/AIR MIX

Multi-port precision electronic fuel injection on the F90 delivers the optimal fuel/air mix to each cylinder.

VARIABLE TROLLING SYSTEM

The tiller handle models come standard with Yamaha's Variable Trolling Speed feature, allowing the operator to stay on the fish by selecting the preferred rpm (in 50 rpm increments) within a range of 620-900 rpm!

HIGH AND DRY

A top-mounted flywheel keeps sensitive electrical components out of the water.

OPTIMUM PERFORMANCE

An ECM (Engine Control Module) adjusts timing to maintain optimum engine performance, economy and reliability in all conditions.

FEWER MOVING PARTS

The double overhead cam design on the F75 and up features fewer moving parts compared to a conventional single overhead cam design for greater reliability.

MULTI-FUNCTION TILLER HANDLE

Available on F30 through F60, and optional on F75 through F115, the multi-function tiller handle gives you fingertip control of starting, shifting, steering and throttle.
