Bill welcome aboard
What year is the boat? Is there any signs that a tank was where you think it should be (in the floor)? Just wondering if it developed a leak and someone fitted this bow tank. I would think a bow tank for this size boat will change its angle of ride however it may help keep the bow down when getting onto plane. Got some pictures to post?
