The Low-Line Answer to Smooth,Fuel-Saving FishingDirect Injection & Turbo ChargerYanmar’s advanced technologies have now produced a 78mmcylinder, direct injection engine. On top of that, fuel costs are hugelyreduced by the high combustion efficiency. Save 15---20% more fuelthan with the pre-combustion chamber models of the past!

Low ProfileComputer analysis has been used to achieve an extraordinarily lowline profile. Suitability for installation in compact engine rooms givesnew flexibility in boat design.

New-type ClutchThe new high performance YX Series clutch gives smooth and quietchanging between forward, neutral and reverse. The fish won’t escapeduring gear changes, the response is immediate and there is virtuallyno shock whatsoever.

Trolling Devices as StandardThe propeller can be adjusted to low speeds without altering the speedof the engine, making precise navigation or fixed point sailing easy.Also low fear of wear or overheating during long trolling operation.

Easy Checks and MaintenanceThe lubrication oil and fuel filters, fuel caps, dipstick, drain ports andfuel feed pump are all located on the operation side for simple checksand maintenance. And since there is no corrodable zinc, there is noneed for troublesome replacements.
