I have two Cat 3176 engines in

I have two Cat 3176 engines in the searay I occasionaly skipper. Recently the performance of the port engine got worse. When I compare the engines it seems that the turbo is not kicking in until 1800rpm on the port but much earlier on the starboard. Any ideas to where to start looking for problems with this would be appreciated as the yacht is out of range of Cat dealers (unless I fly them out and put them in a 5 star hotel!!).

Hi, maybe it would be an idea to eliminate the charge air cooler from your turbo issues, there is a company that manufacture diesel engine charge air coolers. You should try Vestas aircoil A/S in Denmark www.vestas-aircoil.com
Maybe they can advise.
