Salt Water Side Cooling Hoses
Hi...the salt water side cooling hoses on the inlet side of the heat exchanger on my YANMAR diesel are popping off their couplings at high RPM. Everything is normal at low RPM and at operating temp but once I accelerate up to about 85% RPM one end of the hose loosens up and pops off. I'm wondering if this is just a loosening up from thermal expansion of the hose or is significant pressure being built at higher RPM because of a blockage in the heat exchanger? Any ideas?
