What this video covers
Marco demonstrates the process of removing and replacing a knotmeter transducer while the boat remains in the water.0:03 He first unscrews the locking ring on the transducer housing and prepares a dummy plug to minimize water ingress.1:19 Upon pulling the transducer, a small, manageable amount of water enters the hull during the few seconds required to swap the unit for the dummy plug.1:26 The transducer's paddlewheel was fouled with small mussels, preventing it from spinning.1:42 After cleaning the paddlewheel, he repeats the swap process to reinstall the transducer, ensuring it is aligned correctly.2:26 He uses a Surehold PVA sponge and a chamois to soak up the water that entered the bilge during the procedure.2:01 The bilge pump activates to clear the remaining water.2:58 This demonstration shows that while the process causes initial anxiety, the volume of water entering the boat is limited and controllable with proper preparation.
