  • 1977 Mako 20 rebuild

    Just picked up this 1977 Mako 20 a couple weeks ago and I've already started the rebuild. Thanks to alot of research on this site I feel ready to take it on. My plan is to repower with a Mercury 150 that I already have, replace fuel tank, repair holes a d cracks in fiberglass and paint, and hopefully get it back on the water within a year. So any advice is much appreciated!

    Congrats on the boat! That’s a great model for inshore and near-shore, even a little off-shore if you keep an eye on the weather.

    Lots of good advice and experience is available on this site.

    I’m subscribed and look forward to watching the progress.

      I actually studied your rebuild alot! How much was your fuel tank? Did you get it from sunshine tanks?

        42 gallons, and yes it came from Sunshine Marine Tanks.

          Had a little free time so I started hacking away at the foam. This tank is really in there! Definitely some saturated foam with water and fuel.

            Finally worked the tank out of the coffin. It really doesn't look too bad, some pitting but no leaks. The foam definitely has fuel in it though so It must have been leaking from somewhere. I also talked to sunshine tanks today and Lucy was great but it ended up that shipping was going to kill the budget so she directed me to Florida marine tanks. They also have the drawings for the original aluminum tank and came in about the same price as sunshine and I can just pick it up.

              Worked out the fuel fill and vent lines today. Ended up cutting a hole in the step to cut the bend in the aluminum lines, might put speakers there. Ran the motor on friday,for the first time since purchasing, she fired right up. I feel like it was a really successful week! Should be getting the resin and fiberglass next week so I can start filling holes and cracks, and prepping for paint.

              Any suggestions on paint... thinking about either total boat top coat or interlux brightside.
