I have a sea trial coming up on the 18th of August. I have been advised to be sure to run the engines at WOT for 10-15 minutes to see how they handle the prolonged load and heat dispersion. I usually only run gassers at WOT for 3-5 minutes to see if they reach rated RPM and show any signs of overheat or missing. The engines are the original 1987 Crusdader 350 hp closed cooled with 600 original hours (no rebuilds). Is 10-15 minutes excessive or reasonable? I suppose if a bad storm were coming in I might run those motors at 3800 to get in quicker (4000-4400 is rated max) so why not run them at max for ten minutes?
The boat is 34,000 pounds and is a planning hull. I intend to find her sweet spot for mileage and run it there (Garmin 5015 with flow meters). I typically never run my big blocks over 3200 for a cruise RPM. Bill
