Kamd44 heating issues

[derekh]

Hi, I hope i can be steered here to do the right thing. I believe reading forums that my heating problem on my kamd44’s is a partially blocked heat exchanger (both engines run too warm over 3000 rpm) can these be cleaned without removal as in my boat access to one of them is a massive job. (Galley removal antares 1080) can someone who has done the job share method which works. Thinking sbout rydlyme.
Very many thanks.

Rydlyme is what we use in the workshop, works very well. You need to make up a system where it pumps into the rawwater inlet on the engine and returns from the exhaust elbow hose into a container with a bilge pump to circulate it, definitely saves a lot of work.
