    Outboard Conversion on 3270-gctid345480

    Just curious.. has anyone seen this? The transom seems pretty thick but do you suppose it would still need to be reinforced?

    There was some guy overseas talking about doing this...like in the middle east. You might find his posts by searching. No offense, but this seems like a reason to get another boat. On the other hard, some other fella on here has a 3270 without engines, and he wants to sell. op

      Just a heads up. That transom has seven seperate pieces of soaking wet lumberyard fir plywood in it with voids around all the ply edges and in various other locations. Not exactly what you want to mount those four Yamaha 250HP outboards to. But it would be pretty cool. You could mount them on PowerLifts and be a real topic of discussion at the Bayliner Rendevous. Just think, instead of the ten foot wall of water following the boat, you would have four twenty foot rooster tails.

        Cheaper to put 2 volvo D6 370's Than building a pod and 3-4 large outboards might as well look at the IPS drives LOL:worth

          Since origionals seem quite happy with two 150 HP engines, why would one need more than two 200 HP outboards tied to fore and aft stringers inside transom?

            Ping Steve (pika steve). He recently completed a repower on a 45 footer; and I think in hindsight affirmed that outboards might have been a viable option. The 3270 is a semi displacement hull and has the capacity to perform well with lower HP engines. Two 250 HP engines would be excessive for that hull.

              Sounds like you might have an axe to grind.

                  Well we didnt actualy put an outboard on the transom, but we did cicnch a 19 foot boat into a pocket in the swim grid. Engine was a 150 hp Suzuki 4 stroke, but still propped for the 19 footer. Did 5.5 knots at I think about 2200 rpm,.... pushed it up to 7 knots quite easily at 2800? Ish rpm. Did not want to push harder as we were just transporting the 4588, and did not want a calamity. Very very quiet smooth ride. Getting rid of the struts and rudders, and have the correct props installed and I would think that a pair of 90s would be plenty. I would not be afraid of pushing a 4 stroke Suzuki pretty hard. I have abused my suzuki 140 for 6-8 years at 5000 ish steady rpm and it ran as well as it did when we bought it. Did have to buy a new one when it snapped off the back of the boat one day. We were not sure if we hit a log,.....or jumping 8 foot waves broke it

                  I will try to get a pic up of the 4588 being pushed by this goofy setup.

                  Cheers steve
