Albin 35 Port Engine Overheating

[TD]

I have a 2000 35' Pilot House TE with Twin 370HP Cunmins engines. My port engine gauge would go upt to 200 degrees F in a short time and at times would fluctuate even after I brought the RPM back down around 1000RPM. After cleaning the sea strainer, back flushing the air, oil and engine heat exchangers I noticed that the 1 1/2 inch diameter discharge hose from the engine heat exchanger to the exhaust elbow had a bad kink at the exhaust elbow connection. I replaced the hose with a Mercury molded hose with two elbows because Cummins people said it was an Albin add on. This hose was obviously the wrong hose because it was not a molded hose capable of making the two 90 degree turns required for good connection. It had a spring inside to prevent kinking, but over time it weakened and bent at the exhaust elbow restricting the flow to less than 25%. I don't know if anyone else has ever experienced this--so I decided to share the info in case it might help someone. I will test the boat sometime next week to make sure this was the only problem.

TD,
Thank you for the post. We appreciate your time and knowledge.

I had the same flexible exhaust hose with kink on my 450 Cummins. I think it was responsible for blowing out a cooling hose (which nearly sunk the boat). When we replaced the cooling hose, we re-engineered the exhaust discharge hose with 2 90 degree elbow hoses connected with a stainless pipe.

Here's a pic.



ps - I sure wish Cummins engines didn't get so nasty looking.
