I did all of that myself and if you are limber and at all mechanical there is no reason to farm that stuff out. Until you get into serious internal engine stuff or the fuel controls these Diesel engines are literally as simple or even simpler that the Gas Big blocks to work on. You will find plenty of guidance on this due as well as SBMarine to do a lot of it yourself. I was where you are five years ago when we bought our 44. It was 9 years old with 118 hours on it. I slowly and methodically learned as much as I could about the engines and just dove right in to doing my own service.Aftercoolers & heat exhanger replace or repair?
I am getting another step closer to be the proud owner of a 44. Yeah! Engine and boat surveys are done. The fluid anlysis was fine. I am concerned about what the commin tech/surveyor deemed important action items. These 3 items are the most expensive:
The boat purchase took a big bite out of our savings. We are hoping to reduce the added expenses but not to endanger ourselves with broken down engines in the middle of the sea. I'm pretty handy with cars and house repairs but ignorant about disel engines. What's your opinion on reconditioning (not sure the correct term) vs replacing? How soon should I do these repairs? Thank you in advance!
- The aftercooler housing seals are leaking and the aftercoolers are in poor condition and should be replaced. $7,500 (parts)
- The marine heat exchanger is leaking and is in poor condition. Replace heat exchanger and all related seawater and cooling hoses. $400 (parts)
- Port Engine: Replace wet exhaust elbow hose and all related clamps. The hose has been leaking seawater and is in poor condition. $450 (parts)
- Labor: $6,500 for above and a few miscellaneous items.
