Atlantic 21 Single Engine?

[Viper]

Hi,

Can't afford new so am now looking for some pre-owned engines for my Atlantic, and although I would prefer twins, because of difficulties in getting two the same I am considering putting a single on the Atlantic instead.

The transom measures 21". As the long leg outboard is 20", and the extra long is 25" is it better to have the long but 1" short of the transom or have the leg sat in the water 4" ?

If any of you have a single on an Atlantic what did you go for.

Before anyone suggests it I will not be chopping the transom out as there is only 3" of it above the deck anyway!

Any thoughts?

21"

4" of leg under the hull will drag like mad.
