What this video covers

Huub replaces the upper and lower seals on Yanmar saildrives to prevent water ingress and oil leaks.▶ 3:17 The process begins by removing the propeller and the cone, then draining the gear oil.▶ 0:05 After cleaning the internal components with diesel and 150-grit sandpaper, the crew installs two new lower seals in opposing orientations—one with the opening facing down and the other facing up—to ensure a proper barrier.▶ 4:08 The team replaces the zinc anodes and applies marine lithium grease to the assembly.▶ 6:07 To access the upper seal, the crew disconnects the throttle cable, wiring, and engine mount bolts, then shifts the engine aft to extract the saildrive unit.▶ 7:37 After scraping away old sealant from the hull interface, they prime the bare aluminium with Etsy primer and apply PrimoComp and Trilux 33 anti-fouling paint.▶ 11:40 The unit is reinstalled with fresh sealant and the engine is realigned to reconnect the shaft.▶ 13:12
