Please help. I am asking for a buddy of mine who has a searay 268 sundancer with a dry weight of about 5500 pounds. The boat was repowered with a 383 Mag Bravo V4. The question is that he is trying to replace the drive and that outdrive to me looks like a bravo 1 based on the shifter cover on the front of the drive. However I do know that bravo 1 and 2 look simmilar. I guess the main question would be, what is the proper drive and gear ratio to accomodate that type of engine with that size boat ? Any insight will be greatly appreciated. Thank You
