Yamaha 90 Hp Four Stroke – F90LB – Forward Control

Larger 81mm Cylinder Bore –The previous-generation F90 used a 79mm cylinder bore, in the next-generation F90 the cylinder bore size has been increased from 79mm to 81mm which provides more efficient power delivery. A larger valve has been used for increased transfer efficiency for both intake and exhaust.

Offset Crankshaft –The crankshaft design is offset by 5mm from the centre of the cylinder. This innovative design decreases internal friction and promotes a more efficient transfer of power to the crankshaft.

Alloy White K Series –These props deliver Yamaha’s high-quality design and performance in a low-cost, lightweight propeller. They offer a good all-round choice for Yamaha outboards, coming in a wide range of sizes and pitches to suit every power requirement.

One-Piece Cowling –This engine features a new outer cowling design with an intake air drain system, to easily and efficiently drain away any water that enters the cowling during normal engine operation. Incoming air is routed through a labyrinth of passages that help trap and drain water before it enters the engine’s intake, for maximum reliability.

Single Bore Throttle Body –The 60mm wide single bore throttle intake minimises intake resistance and provides first-rate response for brisk-acceleration and high-speed operation.
