This is a brand new Canyon Marine bottom laid up by Kevin Felkins in Lodi, CA. The old boat had some bottom issues, so the top deck and capsule from the Lucas oil "Shazam" boat driven by Tony Scarlata will be used with the new bottom.

De rigging the old boat to use the hardware in the new boat

The new boat

First process is to flip the boat upside down and locate the center of the boat. The strut and fin will be mounted first.

Just curious what made you guys decide to build a new hull. Knowing the level of talent on that team the old one must have had some issues that couldn't be fixed.

I couldn't imagine drilling into a new boat, I was freaking out mounting a footrest in mine. :eek

The bottom of the boat was not repairable for the speeds these boats see. Laying up a new bottom was the best option and swapping the parts over.

Very cool!

What does the cutter that is used to cut the prop shaft hole look like? How do they keep it from "walking" sideways when the hole is started with all of that overhang forward of the strut?

That was my question as well sir. Do you mind elaborating on what was wrong with the bottom?

Thanks

The Canyon bottom has a "crown" to it. This original bottom had been repaired and sanded on so much over time, it had lost its crown. It would never be right if you tried to put that back in it.

Thank you.

I was curious of the reason for sure.

I really like that prop turner. ;)

View attachment 557785

It's basically a long 1 1/8" hole saw attachment to the prop shaft end. The prop shaft has been modified to fit into the drill on the other end. To keep it from walking, we have a homemade tool that was made to press down on the hole saw attachment as it's cutting through the bottom.

I imagine there is plenty of clearance between the hole and the propshaft when the log seal goes on, yes?

Not really. On this particular boat the bottom of the boat (inside) has to be ground down for clearance because the strut angle is so shallow.

Im talking about the clearance around the circumference of the shaft and the hole saw hole for the propshaft.

Sorry I misunderstood your question. Yes it actually might be a 1 3/8"-1/2" hole saw attachment that we use so that there is plenty of clearance between the prop and the hole itself.

Thank you. It's still gotta get the cap finished and a few other things buttoned up. Then it will get broken down and some things will get sent out for anodizing. This boat is gonna be getting a wrap done to it. I'll post pics when it's done. Testing is gonna be in Bakersfield on May 20th for the NJBA drags. 1st race will be June 9th weekend in Wheatland MO for the LODBRS.

Great write up. Thanks for sharing, I'm with the other guys, not totally understanding the process, there's got to be a bit of a pucker factor when you start up that big drill.........

No doubt. I don't have the stones to put a drill to a blank hull.

Especially strut/prop shaft location.

Oh there is for sure. The strut location is already recessed in the mold when it comes out. It then just depends on the strut angle to determine where it's going to come through the boat. It's still a sketchy process when your looking down the barrel of the drill!

7 Degrees or less maybe?
Thanks

Possibly [emoji848] I can't give you the exact number, but yes it's close to that.

Thanks,

I aint always the sharpest knife in the drawer. :p

I was in class on lunch when I typed that and after thinking about it didn't want to pull my phone out and correct it.

Drilling holes in other people's boats hurts a whole lot less! :D

Bitchen boat and man what a quick build! Thank you for sharing it with us! Seems like everything you touch ends up over the top. ;)

It's a core saw which is a lot like a really deep hole saw without a pilot drill which is why other means need to be used to keep it from walking.

What would those "other means" be? I recall a picture from a Prime Marine build thread where a second guy was lying on his back using his feet on the drill shaft? (hull was right side up on a dolly)

That core saw must want to walk right across the hull when you start the hole with all that overhang beyond the strut.

Slow and slower when getting the hole saw started for sure.

Just got back from Wheatland Mo. today and we had a great weekend with the boat. We already set the ET and MPH record at the last race in Marble Falls TX and this weekend we broke them both again TWICE! [emoji1303] The old record was 5.08 @ 168. New record is 5.01 @ 169
