Hi all. I just noticed a tapping/ticking noise coming from the front of my engine. This noise was not there a few weeks ago. The noise seems to be there through the entire rpm range. It seems that maybe it is coming from the injector pump. The boat is pretty new to me so I don't know much as far as maintenance history but according to the gauges it is around 2500 hours. If they are accurate. I tried an oil and fuel filter change and that didn't help. I plan to adjust the valves but I don't think this sound is valves. Does anyone have any ideas what this sound may be? Any maintenance or troubleshooting that I can do on the injector pump? Engine starts and performs just fine. Just has this noise which I am concerned about.
Any help is greatly appreciated
