Can someone tell me what pumps/forces water into the J-Tube/J-Pipe to cool the exhaust manifold? I believe I have a clog that is causing and overheating issue, but can’t figure out where. Is there a separate pump?
Series of events leading to said question: Struck a submerged log or tree (still don’t know what it was because it stayed under the surface). I immediately realized I had a jammed impeller and got a temp alarm within 15 seconds. I limped off the water on the starboard engine to diagnose on land.
Candoo is giving me code P0562, which is “Battery Voltage Too Low” I’m not sure this code is even related because I may not have cleared this code from last year when I replaced the regulator/rectifier.
I cleared a 3” piece of wood that was caught in the port side impeller. I removed the J-Pipe and there were no visible clogs. I blew compressed air through all orafices of the tube and nothing but residual water came out. I blew through the rubber tube with my mouth that feeds the J-Pipe from the back of the boat (same one that you hook up to a garden hose) and there was no resistance/clog. I replaced the water box temp sensor with a brand new sensor, but I am still getting a temp alarm. The J-Pipe is screaming hot after testing on the water. I poured bottled water on it, which boiled and steamed off immediately, while I can hold the starboard J-Pipe with my hand. So, clearly water is not flowing through the J-Pipe. Additionally, when testing on the water, the port engine RPMs are about a 1,000 lower than the starboard engine.
Where else can I look for a clog?
Is there any chance that a damaged wear ring or impeller could be preventing water from feeding into the exhaust manifold?
Thanks in advance for any info.
