1. Lubricate engine coupler splines through grease fittings on coupler by applying
approximately 8 to 10 pumps of grease from a typical hand‑operated grease gun.
NOTE: If the boat is operated at idle for prolonged periods of time, coupler should be
lubricated every 150 hours.
Tube Ref No.
NOTE: Your Vazer 100 power package is equipped with a sealed engine coupler and
Perm‑a‑Lube U‑joints. The sealed coupler and shaft splines can be lubricated without
removing the sterndrive. The Perm‑a‑Lube U‑joints do not require lubrication.
