Welcome to the CGOAMN Dean !
You might have trouble squeezing two motors onto your transom, pretty tight for just one ...
If ya could squeeze two on, setting up a steering system would also be a problem.
My V-156 came with a 1971 Merc 65 HP motor with out tilt & trim and I could get about 36 mph on gps with a 17P prop, third hole out on trim, latter replaced it with a 1994 Johnson 60 HP motor with T&T and could get about 41 mph on gps with 19P prop ( just me in the boat with a light load of fuel) a 17P would work with some people in the boat or pulling tube/skiers.
A newer 70 to 90 HP Johnson/Evinrude would work well on that hull.
My 60 HP Johnson would go all day on 9 gals. of fuel ... while my 115 HP Merc/Mariner takes 20 plus gals to do the same ...
Post some pictures of your V-156 ...
