Qué cubre este vídeo

The crew of the 45-foot former fishing trawler HMAS Colander attempts to rebuild a 45-year-old Mariner outboard motor after it develops severe internal noise during dinghy operations.9:27 Disassembly reveals rust in the cylinder bores and significant carbon buildup, though the pistons and fire rings remain in good condition.10:26 The host sources new piston rings and two replacement bearings from a Yamaha dealer, noting that the Mariner block is a rebadged Yamaha design.23:03 The project involves sending the block to a local machine shop for honing and decking to ensure a proper seal with a new gasket set.22:04 While the engine remains a two-stroke, the rebuild aims to restore reliability for a total cost of approximately $600 in parts and machining.23:33 Separately, the crew addresses water ingress issues on their electric scooters by replacing plastic base plates with custom-machined aluminum components to improve durability in a saltwater environment.31:14
