    This may sound like a dumb question, but how long is my Mid 80's Regal Medallian 195?

    I swear I measured and it was 21' but the name implies 19 1/2 feet. I want to order a cover for the winter time. Anyone know my beam width by chance? Is my boat considered to be good?

    Alpha 1-MR Brand new shift cable, bellows, and lots of other parts. If I have my engine running in my driveway (with the ear-muffs on), I can shift from neutral, into gear, and easily shift back. However, if I'm in the water, I can shift from neutral to drive no problem, but if I try to...

    Alpha-1 MR: Slight knocking at max turn. New coupler,spline shaft, and u-joints.

    Okay here's the story. Bought the boat, Alpha-1 MR, 4.3 GM, blown motor. Repowered by marinizing a 4.3 vortec, didn't align my motor, blew my coupler after about 20 hours of use. (altho the boat ran great) Replaced coupler, in the process converted from the round style to the triangular...
