About Mercruiser alpha 1 water pump kit

It is VERY important to know if you have an Alpha One or a pre-alpha / "R" style drive.
If you screw up and try to install the wrong water pump base you can destroy the outdrive.

Some Alpha Ones might not be using the pump in the drive but instead
have elected to use a belt driven sea water pump.
This is usually the case with closed cooling system equipped engines.
Belt Driven Raw Water Pumps are also used on engines with Bravo drives.
