I recently replaced the impeller on my 1988 Bayliner OMC Cobra 3.0 I/O and the shop who did it last time installed it wrong as some of the fins were one way and some going the opposite direction. I took the boat out today for the first time and the temp was right around 170 but the valve cover was hot and started making a light ticking sound. When installing the impeller in the housing should I turn it clockwise or counter-clockwise?
