Just 2 weeks ago, using the resources in that forum, I actually was able to diagnosis my 7 year old Hot tub as having a leaky seal on the water pump impeller which caused my 4hp motor front bearings to fail.
(ouch, $350-ish down the drain.....)
A true redneck would'nt mind a little oil in the water. Throw a little Simple Green or Purple Power in there and it would be great for cleaning transmissions though!LOL
