I cleaned my Yanmar (100hp Turbo) heat exchanger at about 2,000 hours because the temperature would rise at higher speeds. It was perfectly clean and did not need cleaning. Be sure that you have the Yanmar replacement gaskets and O rings for this job before you start. They take time to get because many dealers do not stock them...this may be because many owners do not clean the heat exchangers.
BTW, it turned out that the heating problem was some debris small enough to get through the salt water strainer in the Vetus sea chest, but larger than the small holes inside the transmission oil cooler. About every 2 or 3 years, loosen the hose clamp on the rubber boot on the sea chest side of the transmission oil cooler and using a wet/dry vacuum, suck out any debris that is lodged there.
