What this video covers
The engine on a Tayana 47 CC, currently docked in Hout Bay, South Africa, suffered a total failure due to water ingress.0:45 The motor is hydro-locked and the pistons are seized, likely caused by a blocked anti-siphon valve that allowed seawater to backflow into the cylinders while the boat sat idle for three months.1:27 Because the engine is an older model and the internal damage is extensive, the owner determined it is unrepairable and requires a full replacement.1:38 Plans are underway to relocate the vessel to Royal Cape for a haul-out and engine swap, which will involve removing the generator to create enough clearance to extract the motor through the interior rather than cutting the cockpit floor.8:08 While managing this setback, the crew continues to work on other systems, including the installation of a second Victron MultiPlus inverter-charger to increase total capacity to 6,000 watts.17:34
