Have disconnected the vro, checked compression(150 both), new power pack, thermo ok. Sometimes runs ok. Sometimes goes in s.l.o.w mode. No alarms. Have checked wiring and can find no shorts. Have tried to force the engine to go into s.l.o.w mode while running(wiggle wires) but to no avail. Makes me nuts. Want to use my boat. Any help?
Thanks in advance.
