You don't see to many V-20's with twins. Interesting.

with the exceedingly rare "cubby" cabin... lol

Wow - an offshore tuna rig.

Interesting setup. I wonder if one engine is enough to get up on plane? My very first v20 (a LOOOOOOng time ago) had a 65hp I/O in it (don't ask) and I can state from experience that it was not enough to get on plane.. you could feel that it was just on the verge, but wouldn't do it. My point is if one of those engines quit on him would he have enough with a single engine to get on plane coming back to the dock? I gotta admit I like the setup, and except for the seats, the boat itself looks pretty well taken care of... although I would have liked a pic of the inside of the "cubby" cabin..

Clean Boat! I'd bet 140 horses will kick her right along. Looks well taken care of.

almost no twin engine boat will plane on one engine without a prop change

If proped for twins, I totally agree. Just as no twin setup will deliver x2 the amount of HP that a single will. (Two 70 hp engines will not give the equivalent speed of a 140 hp single). But it still doesn't answer the question.... What hp does a V20 require in order to break free and get up on plane? Let's presume he has one engine go out, so he raises that one, and changes the prop on the other one, and it's a dead calm day on the water. Will the one 70 be enough to get him on plane? I seem to recall somewhere that someone in here had a 90 hp engine and they claimed they could get up on plane, and I know from personal experience that a 65 hp engine just will not do it. So what's the minimum hp necessary?

i think 90 is the generally accepted min..... my 1975 115 T.O.P. has no problem planing the boat.... supposedly it's the equivalent of a modern 90 though I'm not completely convinced that Karl didn't put a little something extra in the old mercs

Just for the sake of conversation, one possible exception to that might be an exceptionally heavy slow boat where the extra surface area of the second prop MAY reduce slip% enough to increase speed or even plane where otherwise it wouldn't...
