MADD CATT -41" fantasim saw build

[Cooper]

She is going to hit over xxx mph (goal hopefuls of triples) eventually with 1527s I'm going to be pushing mid 50k

Very cool! Good choice on the motors, the 1717's are a VERY tight fit. What stingers are you using?

Yes , originally I was looking at the 1717's but just didn't want to put a s bend in. I did and have been for some time been thinking of a simple (robust) gearbox. Have motors flat. I'm using the stinger that have the pedestal mount onto the overhang. I kept bending the other ones on my shocker, not from crashes but from power, once they bent they just bend more.

Subbed. Best of luck with the build.

I don't think twin SF 300s will fit.
I have one here that isn't being used... If you want to see one in person and see how it fits in the hull let me know. I could ship it to you as long as you pay to ship it back.

yes you are right too big! And I'll start this build for ya, thanks

once they bent they just bend more.

Same thing on my Explorer cat. Someone noticed it at the SAW races and I bent them back to straight. After every run I made, they were bent back in. I had extremely short stuffing tubes/flexes in that cat so it probably made it even more pronounced.

Ditto on that,pedestals are a neccesary.But.. are you going with something like "click" drives or the ones from FC or HOR?
These puppies are nice https://www.mtc-powerboat.de/index.p...=13&produkt=85I just throw these out there as they have a larger shaft/bushing Dia so should wear better and be more stable.

always nice to see more choices, one of the few things I have had for this is the stingers, the simple ones from fc and hor.

I had problems with mine bending outward on the Shocker.

Ha. yeah an S bend is required...my tubes are very short with a slight s bend. I have also had issues with the stingers running out on me. Keith can point you in the right direction on what stingers work best with this hull.

I'm more concerned with the bottom of this boat than the top. Always try and get as sharp, square, clean edges on any surface below waterline. I always try for square below water and round above. Water exiting off an object into air will have less restrictions/turbulence from a clean square edge than a round surface. (at high speeds). I was rather happy with this hull as there were only a few places that needed extra work. Most were able to be cleaned up by just sanding.

Wanted a sun roof! Naaa, I want the complete sleek look so I removed the mock air scoop.

It seems wood has been disappearing from recent builds. But nothin like plane ole wood.

The hatch is just chop fiberglass and gelcoat. I'm reinforcing with carbon/Kevlar. I'm going to be using foam seal on the hatch with bolts. The wood around the perimeter will help in the mating surface of hull to hatch. The wood will be epoxied to the hatch followed by a cf/k weave. I made sever serrations in the wood as the hatch has a slight curve and it needs to stay for matching up to the hull. A layer of marine epoxy with milled fiberglass will cover the top of the wood where the air scoop was, then sanded flush.

After a trip to my mothers house I found her old singer sewing machine. Trying to explain why I needed it, sewing carbon and Kevlar, she thought I was making body armor,,,,lol,, I never used one before but after about 1/2 hour I was up and sewing! I have spray glued light fiberglass cloth to carbon/Kevlar cloth to get very clean edges. I have used tape on the edges so it would not fray. I have never used the stitching method so this was new for me. On this piece I did tape the outside before I cut but later for the inside of the hull I will just use the stitching , so that's when I'll be able to comment on how well it works for me. The painters masking tape is just to keep epoxy off the hatch. No matter how hard I try not to get it on my fingers I always do. Kinda like a kid with chocolate bar on a hot summer day, end up wearing it!!

Getting ready to cook! (not really cooking it! Just using warm water from the tap. Letting it sit for about ten minuets. The epoxy will flow better, mix better, and possibly set up quicker if working temp is around 70~80 degrees. )
