I have twin Volvo TMD40A motors driving My 31 foot Mariner flybridge cruise, I have an over heating problem above 2800 revs.
I have removed and cleaned the oil coolers and heat exchangers as well as replacing the exaust mixers
the motors have done 2900 hours and are serviced every 12 months and do not need oil top ups between services
Dose any one have any clues

Dirty hull or props?
Raw water impellers?
Raw water pump internal wear or end plate wear or leaky seals?
Blocked pickups or strainers?
Thermostats?
Any aftercooler on that model?
