Hi guys,
I have replaced impellers in outboards before but now on my Mercruiser 5.0 MPI with Alpha drive I am so confused if it has an impeller I have to replace/maintain as a regular maintenance too. Looking at the Service Manual I still confused because the manual talk about different models and in the illustrations they show an impeller. I know mine has a water pump in the engine for sure but when have a water pump, it uses an impeller too (perhaps to move water up so the water pump can pick it up?) Im trying to avoid remove the lower unit just to check.
Thanks in advance.
