    Got a new toy to test out eventually...

    I will assume it is a SD Card. SanDisk, part of Western Digital, does, or did, have a Data Recovery Service.

    Trailer fit?

    The Boat is a couple of Inches too far back, as those Bunks are unsupported Wood. I would than either cut the Bunks, or move them forward, until the End is directly above the Connection to the Trailer Frame. that is where I would have the Transom, located.

    It will fit. The 78 likely is a Older Style, with a less streamlined shape. My 78 90 had the post 78 gearcase on it.

    Actually, if the engine is completely Antifriction Bearing, including Piston Pin, it can survive running at idle with No Oil.

    Suggestions on how to fill my onboard gas tank?

    Premixing prior to adding to the Boat Tank is the only way to insure a Consistent Mix. Contrary to Popular Belief, the Oil does not Self-mix very well, especially when the Tank is more than 1/2 full and not subject to serious G Forces to sloth the Mix around.

    Mercury thunderbolt 500

    Based on the Cowl and Faceplate Decals, I'm almost 100% certain it is a 73 A 73 has Mercury Marine on the Face Plate, a 72 would have Kiekhaefer Mercury In 74 the two blue stripes would have not gone under the Face Plate. Granted, this is my 1984 115, kinda looks like a 71, cause I put the 71...
