Ill take a pic, its like some one grinded it all off to re-do it all. The water pump was covered. Where the cone is looks like it would take 5 gallons of resin to fill its a big gap. Maybe fill the big voil with filler then epoxy ontop? Ill get a pic when i get home.

I epoxy my cones on, and use epoxy to do all the fill work. I had to redo a cone for someone and had to do what you described, grinding out the sides. To do a full glue on and fill the sides I use about half of the regular size cans of west system.

The 410 works, I usually add a touch of the 403 microfibers to thicken it up a touch. The 407 works great too. Just don't go crazy with the microfibers if your doing a top coat as it takes forever to sand. If you have a large gap between the cone and the case I would fill it with epoxy with the microfibers or fill it with fiberglass resin.

Do yourself a favor and get the rest out of the other side too, you don't want to have to redo the other side later.

Yea i think that would be a good idea. Whats every ones guess on top speed with a single 200 blackmax? Hoping for atleast 60mph. Could aways do a bit of engine work for a bit more power. Maybe i need to hang 2 of these on the back? Lol

My dads old scorpion (same hull) with a 200 xri was doing 66-68. I'd guess you should be around the same.

^ mines a scorpion to i just cant edit the title lol and thats a respectable speed for a single 200, go see paul for a few upgrades and get it to crest 70. Only thing i dont like about the scorpion hull is the angled transom sides. Nothing the jig saw and some glass wont fix since i would like to eliminate the splashwell. Any specs or pics on how your dads was rigged and what prop? Ive got 3 quicksilver choppers to choose from, a 24,26 and 28 pitch.

His had a bobs cone, 5.5" cmc hydraulic jackplate with 2" spacers, and a 28 chopper for the calm water and a 30 cleaver for the rough water.
