We were able to be aboard one day for the manufacturer’s sea trials. This is where the engine manufacturer and Marlow test run the boat at various RPM’s and speeds to record performance specs. Depending on the outcome, they may make changes to the props, engines or both.
On this day, I had the camera rolling out back as they brought Steppin’ Out from idle to wide open throttle (WOT) in 45 seconds. Turn up your sound and listen to the beauty of 8 turbo’s spool up to produce 2400 hp and send her cruising through Tampa Bay at just under 26 knots (29.9 mph)! That was impressive for a boat weighing right at 140,000 lbs!
What they learned from the sea trial was that the props and engines were perfectly tuned and balanced so no changes were needed! Compared to our last boat (also a Marlow that we bought used) this one rides soooo smooth! No vibrations and so little noise at the helm (71 db) you have to check the gauges to make sure the engines are running!
