Re: 1989 20ft Wellcraft CC with twin motors
Still think its too much weight, when I say too much its not that its going to sink but the stern is going to be sitting significantly lower than it used to....The Sea-Drive as you stated lifts the whole engine almost into the back of the boat so the set back off the transom is not so bad.....a standard outboard on a bracket does not tilt up like that and will need a lot more set back to be able to tilt it out of the water without hitting the transom....with 2 engines set back like that I believe you will have a problem. And again when I say problem its not that the boat will sink but you may find your floor drain through hulls are now under water and when you come off plane in a hurry you might find your outboards completely submerged.
That said ....go for it and take pics!
