I do not recommend a wire wheel for prep, You will see the wire marks through the paint, it will look like crap.

Scuff the aluminum with Scotch Brite pads, same for conduit rigging. Use vinegar or water down some Ospho to go with the scuffing, not too strong or you will wear out your hands. You can follow up with higher strength Ospho (or Alodine, a good recommendation from Rich) after scuffing, but make sure to rinse it all off well.

Use high strength Ospho on the cage wire and give it time and plenty of coats to eat.
I still think I-10 is the Mason Dixon line.

If you brazed it you need to let it sit outside for a while. The dew will loosen up the flux from brazing and it will flame off easily. If you don't do this it will flake up under the paint. No matter how much you clean it will still be some.

Thanks Gary and Slidin Gator, got the tank mounted and plumbed, got the rigging mostly Painted, seems it's hard to spray the wire, most of the paint just blows away, so I'm thinking about using a paint brush or a roller on the wire mesh, the rest came out looking good. next I'm going to put it all together and ride to see how the motor angle came out.

No doubt, most goes to the wind or the neighbors car. I sprayed mine and it took a good bit of paint. A brush is not a bad plan, the saw grass is gonna wear it off in no time anyway.

I used Mothane 2 part Urethane Black. The primary reason is I can use Rustoleum Appliance Epoxy from a rattlecan for touch up and it matches well.

Maiden Voyage today, 5 weeks since purchasing the hull, It ran smooth, no hopping, very free riding hull, It got on plane with no effort at all, It seemed to be on plane already just above idle. It rides like a sled, not at all like a boat. It is now my favorite riding hull, can't wait till I can take it out riding all day, I put a tank at the same level as the servo, and had no starting issues at all with the fuel injection, just hit start button and it started right away every time. I didn't need to use the electric pump to start it. My idea with tank location is so the fuel doesn't drain back down from the fuel lines back into the tank, which would then cause me to use electric fuel pump to prime the fuel lines and sometimes flood the engine then use WOT to clear the gas to where it will start again. I will know more when I take it out all day and do several stop and starts to see if I'm on to something or not. I put the golf cart top on and am going to install a windshield that swings up and out of the way when not needed. I have the rigging into 3 parts, the engine stand is attached to the instrument panel and battery, the seats are stand alone with just one plug to unplug the lights when removing it, the cage is also stand alone with one plug for lights to unplug as well when removing it. This way I can take the boat apart in less than 30 minutes, switch engines when needed. So next project with be to build engine stand for the 520 to mount on this hull using the same cage and seating, The instrument panel for the 520 will also be mounted to that engine stand which also will be between the 2 seats in the same location.

Excellent. Congrats on the maiden voyage. Yea, they plane very easily. I wonder how different it will run with the 520. Let me know when you're going out. I'll ride with ya.

Thanks Sniper, I got my mufflers welded on today, Last night had Glades Cat check out my new build, Thanks Rick, and went for a nice night ride with Gary, Boat is Riding great, The tank location seems to have solved hot starting issues with the fuel injection, I shut down with the mag switches and restart it's starting on the first revolution, I believe I'm ready to take it to the Freedom Ride at Lake Kissimmee so I can try run the hill, The real test to see if this hull and motor are a perfect fit.

Built the Grass Rake Storage, Need dry storage, the under deck storage area get wet from condensation every day, But the grass rake works very well, I built one for my other boat and it is easy access, plus gives me a step and or a seat, I'm going to wrap it next

Thanks, Slidin Gator, are you planning to ride the Freedom Ride Feb 22 ? I'm planning to park and camp Friday and Saturday nights at Shady Oaks, they have water and electric hook-up there. A friend of mine Carter, stays at Camp Mack because they have rooms there. I gotta try the Obama Ridge with my new boat.

It was a very cold and windy day at Lake Kissimmee, I'm very happy with the way this Scorpion rides and slides, handles the waves great too, But my favorite test was Obama Ridge, it slide right to the top with 200 HP, and on the sticky grass along the shores of the lake, again no problem .
Was a great turn out at the Freedom Ride, even had some from Texas and Nebraska

...and you were worried? That is a great riding boat. You did a great job putting it together.
Slide on brother.

Got everything ready to do a top end on this motor, Log Book shows it had 2500 hours since last major overhaul when it was removed from airplane, #2 cylinder is dripping oil out the intake, So now I'll see how much more power I'll get with fresh top end, I'm expecting to feel the difference.
