OK, at least for me. I have been having problems with my port motor overheating at cruising speed. It idles fine, and if I go at 1000RPM everythinf is normal. Coming from gas engines, things seem to be quite different. When an impeller is bad, the engine overheats at every RPM. I am amazed at the performance of BAD impellers on my CAT engines. If you look at the port Impeller, there are NO fins left at all, yet it still ran fine at lower RPMs.
I have included pictures to you can learn from my mistakes.
