With its twin Cummins MerCruiser 480 hp diesels, Wish List took a mere five seconds to plane. In fact, put the throttles forward and hold on. When the turbos on the Cummins spool up, the acceleration will plumb walk you backward. Running into the steep, close-together head sea, I added some tab to drop the bow and the Willis ran at 20 knots smoothly and dry as a bone. Down-sea, without tab, the bow rose when it met the back of each wave, didn’t swerve or bog down in the slightest.
