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...

I've sen where twins gave more speed than a single of the same combined hp due to the fact the twins were able to provide more lift to the hull, its rare, but I've seen it

How about triple 40 hp outboards on a V ?
