What this video covers
Yona and Shea replace the Hurth transmission on their 38-foot sailboat, Holo Holo, while docked in Guaymas, Mexico.1:01 The project requires removing the propeller shaft to gain clearance for the transmission and bell housing.2:08 During the process, the crew labels all removed parts and performs what they call engine aerobics to navigate the tight engine compartment.1:35 After removing the old unit, they replace the damper plate, which shows significant wear and looseness in its springs, causing excessive engine noise and vibration.4:41 With assistance from a friend, they install the new transmission, reconnect the coupler, and verify the throttle arm clearance.6:02 A subsequent test sail confirms the transmission functions correctly under load.6:59 Yona later disassembles the failed unit to inspect the internal mechanics, identifying excessive play in the clutch plates and a damaged forward thrust washer.8:57 Due to the complexity and cost of a third rebuild, they decide to store the old transmission rather than repair it.9:39
