What this video covers
A DIY dive hookah system for cleaning a boat bottom costs approximately $300 and uses an oil-less 12-volt ACQ908 air pump.0:46 The pump, typically used for live bait wells, draws 7 amps and provides sufficient airflow for shallow-water scrubbing at depths of four feet.0:53 The builder mounted the pump on a plywood board and wired it with a 15-amp circuit breaker and 8 feet of number 10 wire to minimize voltage drop.1:45 The system uses an approved 50-foot diving hose connected to a $25 regulator via a 3/8-to-1/4-inch brass adapter.2:51 Safety features include a quick-release snap hook on a weight belt to prevent the hose from pulling the regulator out of the diver's mouth and a requirement to secure the hose to a deck cleat to avoid straining the compressor.3:58 The builder recommends professional training for diving with compressed air and notes that the pump can also inflate dinghies or clean outboard motor carburetors.4:52
