Default need some information, please

Good morning,

I purchased a 1993 19' Maxum Eddie Bauer edition and am looking for 1) an owners manual and 2) the prop size and pitch.

It has mercruiser stern drive, alpha One gen 2 outdrive, I was told, with a 5.0LX V-8 engine.

Thank you for any help.

You can find the engine and outdrive manuals under Documents of this site. The prop should be marked for size either on the hub or inner ring end.

There is not much to a boat owners manual. What you need is a service manual for the engine and outdrive.

You might need to drop down a pitch, depending on how many hours on boat.
Props have come a long way since 1993, so dont just go out and buy the original prop until you ask others with similar boat.
Search google pictures, you might find some with links.

For Prop pitch, start by taking the boat out.

Get the boat on plane and trimmed out.

Get to Wide Open Throttle.

The engine should be running at between 4400- 4800 RPM.

If you're over 4800, you're under propped and need to increase pitch (or add a blade) or both.

If you're under 4400, you're over propped and need to decrease pitch. Estimate a change of about 200 RPM per inch of pitch.

You can also use the Merc prop calculator to see where it thinks you should be:

Size and pitch should be stamped on the prop hub (<Diameter> x <Pitch>)
