This is directed to Terry Hosmer. I have a 1965 ? 22 1/2 ft., Thunderbird Arapaho with an in line six 150 horse Merc-cruiser. dual fuel tanks and cuddy cabin I've owned for 25 years, the motor has low miles but the out drive casing took a hit on some rocks and cracked lost oil and spun the bearings, it's a rare 13 spline, it only has 2 side portal type side windows, but to large slides on the from of the cabin...I'm trying to find parts for the outdrive, it has a power tilt, and was a very nice cruiser..Thanks
