Look at it this way- what's the cost of an impeller and gasket vs the cost to repair the damage from one that lets you down when you least expect and least want it to?
I agree with Jim, replace it annually! When the impeller fails while the normal driver/owner is skiing and your buddy doesn't pay attention to the temp gauge you'll really regret not replacing that part for less than $50!
I guarantee the repairs will amount to a number greater than a case of impellers!!!
