OK, next step the mechanic want to run at wot for 10 minutes to check all temps , engine power output and any other issues that may come during that event. airbox inspection indicates approx 40% wear , no scoring all rings good. I was a bit taken back as I was under the impression that in pleasure craft with recreational use that a max of 2-3 minutes was the acceptable time for that run up. High idle was fine, ran up and held at 2200 with no issuesm may need a rack adjustment after load test. any comments appreciated.
