It looks like the engine model would have been called the 888 which was made from '71-77. The drive would be the MC-1 model drive. Your drive should have a gear ratio of 1.50:1 which is done with the gears in the upper half of the drive. The gears in the lower half of the drive allow you to go from forward, neutral and reverse. You would want to get the factory service repair manual for it. Mercruiser manual #2 will cover your engine and drive.

All of this info was in a file in the "Adults Only" sticky at the beginning of this forum. If you want to check out the whole file click on this link: How to ID an Alpha Style Outdrive, and History.

Ayuh,.... You have an MC-1 outdrive,.....

There were only 2 raw water pumps used in it, those with a flush port screw, 'n those without the flush port,....

To answer your question on which water pump kit to get... I'm going to post a link to another thread that has the answer. Click here and scroll to post #17, one of our mods Achris answers it in detail. These numbers he gives are Mercruiser/Quicksilver part numbers, personally I like to stick with OEM for it.
