Hi All,
Looking for guidance on troubleshooting and issue with my port engine which will not go over 2000rpm, no turbo boost.
  • Both engines start and idle well with no smoke.
  • Hull has just been cleaned and new VEEM props fitted.
  • Transmission changes without issue
  • Able to power to 8knots at 1400rpm at 8.5litres per hours and runs well.
  • When powering up to WOT to test full speed and new props the port engine stops at 2000rpm and starboard at 3000rpm. Expect 3600rpm.
  • Noticed the port boost was 0. Pulled the rpm back to 1500rpm and the boost on port was still 0 and starboard is 0.9.
  • History, the engines performed well in Jan 24 and WOT at 29knots. Pre purchase inspection found no issues.
  • The props were damaged in Feb and we have been waiting to have then replaced. In the meantime, engines have been started and run in gear with max speed of 4knots.
