Ok, so I replaced my water pump last weekend in response to my mysterious temporary "overheat" condition discussed in my previous post that occurred after cleaning the compressor strainer. Everything went great. Fired it up on the muffs to test everything. Water PSI at idle was 3.5 PSI on the Smartgauge and telltale was strongest it has been since I have had the boat (less than a year).
So, all good so far. Had the cowling off while testing on muffs giving the engine a good look and checking for leaks or anything suspicious. While checking checking everything, I happened to touch the hose coming out of the compressor which after looking in my manual appears to be the 80 PSI air hose from the compressor to the fuel real. The darn thing was so hot it almost burned my hand. I gave it a minute or two and grabbed it again and I felt it go from hot to cool. Is this normal??? Been doing some reading and some have state that the compressor supplies "high pressure cool charged" air to the fuel rails. So my thought is that the air hose should not be hot.
As noted in Savage's signature, I do not particularly suffer from compressor failure fear. LOL. But is always something I am aware of and check as often as possible to check for any warning signs. The engine has approx 400 hours on it. I have also read that the "new" compressor replacement has been "upgraded" with 2 bearings vs the single bearing that the older models have. Does the "new" compressor seem to be having better success than the old style? Would it be a good idea as preventative maintenance to spend the $800 to replace the old compressor now vs $4k later when/ if it goes and requires fuel system cleaning/ possible injectors?
Thanks for all the help!
