14ft Lund with 20" transom.

[Nipper]

Im looking at a 14ft. Lund that has a 20" transom. The owner is telling me it requires a long shaft outboard. From the pictures he sent the prop "looks" rather low.

Questions:
How far below the bottom of the boat should the prop be?

I have a few old Evinrudes and Johnsons I would like to use with this boat but they are not long shaft. Where does one measure from to determine shaft length?

What would be the minimum shaft length for a 20" transom?

If they are not long shaft they are not long shaft. Doesn't matter how they measure. Look up the model numbers and that will tell you shaft length.

The minimum shaft length for a 20" transom is 20" (a long shaft).

I thought I read somewhere that the antiventalation plate is supposed be about 3 inches above the bottom of the boat. I have a 17 ' springbok that is rigged that way.

Haha the old "I read" story. You have no idea how schmartt the guy was, now do you?

A "typical" factory setup will have it slightly below the keel. That's a safe way, but not necessarily the best performance.

You move em up till you maximize performance. 3" could be OK for some hulls, a disaster for others. If you don't have cavitation (especially on turns) and ample cooling water, maybe you're OK. If you DO caviatate at times, and you find she is over-heating and you burn her up, you'll know it was too high...LOL.
