The data above is from my last time on the water. When running the boat on the muffs yesterday I had a weak tell tale and temps rose quickly. Water PSI was 2.5 within spec, but down 1.8 PSI if you look at the above data. I have both style water attachments and neither worked this time. Occasionally I have issues and have to adjust position or water pressure. Ran fine on flush port briefly for testing. Impeller is only two years old, but maybe I screwed it up. Can it be anything other than an impeller like a restriction?
