Mark58 - Saga Over?

Postby Gdcarpenter » Mon Feb 12, 2018 7:01 pm

The first rebuild on this Mark58A died on her first sea trial. Seems I forgot to clean block after bead blasting, my bad and lesson learned the hard way. Scored #3 piston and block. Eventually secured replacement power head, it's block was fine. Rebuilt again with oversize rings filed down to suit. Multiple barrel tests and looking good. First outing went well for about 10 minutes then bogged down.

Make repairs to fuel system and back in the barrel, running fine again. Finally swapped out the Mark35A for the Mark58 on my ZIP and another sea trail. Success at last! Ran (GPS) 32 MPH at about 5,700 RPM with a 2 blade 12" prop. Now to put the Mark35A back on the ZIP as she is sold. The basket case skeleton of a boat in the photo is a 1957 Century Palomino. About 8" longer and about 6" wider, and about 200 lb. heavier than my Zip. Methinks the Mark58 should be a good fit on the new boat. That is, in several years, when I get time to resurrect her.

Gd,

I restored this 1957 Palomino years ago. I would be happy to share any notes and photos that may be of help. Note the tiny little MK50 on the transom.

These are solid mahogany plank hulls. Add a 12-14 gal. gas tank and passengers and you will discover a need for more power. My solution? A white 1962 Merc 700 FGS. Perfect!! I will try to find some decent photos of that rig and post.
