i have had a honda for 8 years now and it has been perfect, the new vtec 150 is a very nice engine so i think you would be fine with it and i have seen quite a few ribs with them, apparently a few boats in chichester have the 150 hondas. some dealers who also sell suzukis rave about the 150 honda.
i did post a engine test of the 150s and the honda was in there, do a search on engines and honda for a read
it does seem that hondas are a bit unfashionable on here but most folks who have them love em
i am unbiased as i have a honda, a yamaha, a mercury and an evinrude
