"Recently I encountered a "short" impeller for my 1987 2.3L Cobra. This impeller's blades are only about 1/2 as long as a standard impeller. I have some evidence that it was intended for either 1987 or 1990 applications (I have also always wondered why the Sierra catalog only shows the standard impeller and enclosure as good for 1988 - 1990 2.3L; not 1987!) The p/n is 986465, vs. the standard impeller p/n 983895.
Does anyone know the history and/or application of this mystery "short" impeller? I have been burning up a lot of standard impellers and housings since I've owned the boat (and know full well about cleaning out the system when one disintegrates); perhaps I should be using this "short" part instead?"
