the issue with rough calibrations on the pump isn't just rough running it can cause some harmful vibrations in the engine. for example if one cylinder fires weakly then the next fires much stronger it induces a large torsional flex in the crank. this might be ok in a car for a while but since boats tend to run closer to wide open for extended times it might cause some issues.
