My first step was, of course, shutting off the fuel valves on both my two fuel tanks. Then I put a bucket under the unit and removed the plastic drain assembly (which I discovered was on the verge of failing) from the bottom of the bowl using an adjustable wrench, thereby allowing quite a bit of fuel to whoosh into the bucket. Loosening the assembly meant rotating it counterclockwise, by the way. Backing off the T-handle at the top of the unit and removing the topside lid, as well as the filter element inside the canister, finished the draining process in short order.
When Regulator Marine decided to vault the 40-foot mark, they did it as only the North Carolina builder can: quad Yamaha outboards, an Armstrong bracket, and a hull ready for virtually any conditions. See the details here. ▶
