What this video covers
The crew of the catamaran Parlay Revival performed an emergency haul-out at Bay of Islands Marina in New Zealand to replace a damaged SD50 saildrive that had a broken gear tooth.0:12 They sourced a replacement SD60 saildrive from a donor and installed it over a weekend, which required modifying the engine bed and bell housing to accommodate the different spline and bolt configuration.1:16 The team also had a worn prop shaft machined and sleeved at a shop in Whangārei to ensure a proper seal, and they replaced a seized seacock with a True Design reinforced plastic valve.10:55 During the initial sea trial, the crew discovered the gear shift cable was reversed, causing the boat to move forward when the throttle was in reverse; they corrected this by re-routing the cable linkage.17:19 The project concluded with a successful splash and engine test, confirming no leaks or vibrations.14:11 Replacing a saildrive requires precise alignment of the engine and spline, and verifying gear shift orientation is essential after any transmission modification.
