Smallest outboard to plane a V boat

[steplift20]

If you want yo go small I would get nothing smaller than a 115 now I'm not saying a 70 hp won't get you on plain but you won't like it, destroyer knows a lot more than me and I mean ALOT MORE but a 115 is the smallest I would get. Are you just cruising around a lake? Than a 70 might work for you. And you have to take this into account,let's say you want to sell it down the road,who will buy it with a 70 hp? But with a 115 it will be sold.
