I have two of these motors and have rebuilt both of them The first one runs well and has strong telltale with good flow from the exhaust tell tale at all RPM. The second one runs well with an occasional light cough at idle but is showing no water flow at the exhaust telltale. The head telltale is very strong just like the other motor. Idle temps at the heads on this motor are 134 Port and 144 at Stbd. Temp at the exhaust manifold is 120. All temps go down when the revs come up. These tests are in a barrel with flowing water so the water temp is up a little.
Should I be concerned that there does not appear to be water flow at the exhaust tell tale. I have not yet tested on the pond.
