That, my friend is a Marlin "Taurus"- I know, because I just completed a 2 year resto of mine! As far as info on these, it's pretty hard to come by, except that the hull bottom was copied by quite a few different boat manufacturers. I have also heard that the Marlins were built in Oregon by former Sidewinder guys, and as such are almost identical to the Sidewinders. Mine runs pretty good with a mild 455 and fresh pump- I haven't GPS'd it yet, so I don't know what my actual top speed is, but it is a blast to drive- Check your hull bottom for hook- The hook in my boat averaged 1/4-3/16" over the last 6 feet of the hull. Good luck, and post some more pics if you can.
