Changing stern drive bellows

Postby 5turbo » Thu Jun 27, 2019 12:29 am

Just doing the yearly maintenance on the boat before she goes into the water, thought it might be of interest to anyone who has a stern drive.

Few pics of removing Yamaha hydra drive unit,

That is a hydraulic pump,

(no direct drive from engine to gear box, oil pressure engages multi plate wet clutch to turn lower unit)

It sits behind 2 covers hence spotless clean,
