About Outboard Motors

Three new four-stroke EFI outboard engines

Mariner outboards has developed three new electronically fuel injected (EFI) four-strokes rated at 80hp (58.8kW), 100hp (73.5kW) and 115hp (84.5kW).

These 1.7 litre outboard engines have been developed as part of the Verado strategy, although they do not bear the Verado name, which is reserved for the supercharged outboards line. They share a common engine architecture with Verado and many components including connecting rods and internal bearings.

The new F80, F100 and F115 are naturally aspirated and have an electronic control module (ECM) featuring a Motorola microprocessor. The processing power provides precise control over the fuel management system and combustion processes, constantly monitoring the engine and making any adjustments necessary to maintain optimum performance and increase safety.

There is reliable, instant starting without any choking or manipulation of the throttle. The self-priming fuel system with integrated fuel supply module is the same as on the Verado outboard motors.

Quiet and smooth running is achieved through an integrated idle relief attenuator and a new cowl design. This combines Verado inspired external styling with air ducting. The acoustic foam-lined cowl is made from engineered polymers, which are lighter and stronger than conventional cowling materials.

So much for mariner outboards, there is, of course, a whole industry around reconditioned engines… see boatpartsdatabase for names and addresses.
