MANDATORY GEARBOX UPDATE

AS OF 08/04/2023

Recent improvements to the Viking 180/195T gearbox have shown increased rigidity. The support of the internal gears has been changed from ball bearings to roller bearings which are much stronger and last longer. This change was brought into effect starting September 2022. All 2023 gearboxes are equipped with the newer and improved roller bearings. Engines with gearboxes purchased prior to September 2022 must be updated.

This update provides:

  • Increased Gear Life

  • Larger Margin of Safety

  • Provision for Increased Oil Level

  • Increased Bearing and Seal Life

  • Stronger and Longer Lasting Gearbox

This is a mandatory update for all Viking 180/195T Gearboxes.

*All upgrades are provided at cost, plus shipping and handling.
