The boat was in service in June and was not used until two weeks before..
The motor runs fine in neutral in all rpm and the props running freely, but in gear the motor will not go over 2000rpm and starts dying and vibrating until I reduce the rpm to 800 again. The oil level is very high (1/2 inch over the gray plastic marker) but the service mechanic said he changed the oil and filed up as requested by Volvo and it would be normal. After some reading I changed the fuel high and low pressure pump, but nothing changed.
Do you have some advice?
