Volvo penta 5.7 motor won't go over 2500 rpm.keeps reverting to safe mode
(London, Ontario Canada)
We have a 2003 Cabrio 257 Larson express cruiser which on August 5 blew a piston. The motor has been rebuilt and on test drives it goes into safe mode (2500rpms). What could be causing this. The mechanics are replacing parts but still not working.
