    The Low-Line Answer to Smooth, Fuel-Saving Fishing Direct Injection & Turbo Charger Yanmar’s advanced technologies have now produced a 78mm cylinder, direct injection engine. On top of that, fuel costs are hugely reduced by the high combustion efficiency. Save 15---20% more fuel than with the pre-combustion chamber models of the past!

    Low Profile Computer analysis has been used to achieve an extraordinarily low line profile. Suitability for installation in compact engine rooms gives new flexibility in boat design.

    New-type Clutch The new high performance YX Series clutch gives smooth and quiet changing between forward, neutral and reverse. The fish won’t escape during gear changes, the response is immediate and there is virtually no shock whatsoever.

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

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