37" TFL Genesis single motor SAW build

[fweasel]

I installed a second layer of carbon cloth over the center tunnel and put a second layer on hatch as well. The first layer dramatically strengthened the tunnel and got rid of most of the flex, but there was just a little left so I cut a piece of carbon that ran from the rear of the sponsons to approximately 8" under the front deck. It covered just the top of the tunnel and the sides, but did not lay down into the bottom of the sponsons. I also cut a piece of carbon cloth to cover the underside of the top deck. I ran it as far forward as I could reach with my foam roller and down the sides to overlap the bottom piece. I should have made my deck stringer templates first, can't do that now until the resin dries.

Holy crap, she is going to be a solid mofo!

This weekend's progress on the Genesis was shot. I either used an expired bottle of hardener or under measured on the scale last weekend as the last round cured but was still ever so tacky to the touch. I gave it all a light sanding and recoated the tacky surfaces with a fresh batch. I even kept the mixing cup as a control and it cured perfect with no issue. I did get a layer of fiberglass cloth laid down on the rear upper deck. I didn't want to use carbon there to keep the location RF friendly for the receiver, GPS, and telemetry. I'm hoping to cut the deck stringer templates this week and get the carbon cut and glued next weekend. I was considering using 3M panel bond, but I think 30min epoxy w/ chopped fiber will be thinner and I'll be able to let it run down the length of the seam before it cures.

I hate it when that happens! Only once early on for me but in a critical location. Grrr.

Made my stringer template and cut them out from carbon plate tonight. trimmed and massaged each one way too many times until they fit just right. The low deck height really made this project tough. Didn't have the patience to epoxy them into the hull, maybe tomorrow. Think I might drill one set of medium sized holes through both just in case I have to route something up front to keep the interior neat.

Oh it is a tuff area to work with for sure. How did you make out?

Working on it now. I'm using 30min epoxy dyed black. The pours down the outside faces of the stingers are smooth and neat with only a few runs down at the tips once the hull was propped up on its side to cure. I mixed in chopped carbon fiber for the pours on the inside faces, which gets clumpy and doesn't run as easily down along the seams. I taped a popsicle stick to a narrow piece of pvc tube to use as a spreader to even out the pour down the entire length of the stringer seam. Doesn't matter in the end, the flotation foam pieces will hide all of it. Unreal how solid the hull feels now, especially when you thump the deck. It used to sound like a hollow drum.

All cured up! This sucker is damn near bulletproof. On to the motor mount and stuffing tube.

Nice work

[MadProps]

nice work its certainly going to be tough enough to handle your high speed saw runs

I just installed those same water thru hull inlets on a Pursuit ....it didnt work out for me for some reason they wouldnt pickup water for me ????
I installed them flush and level with the hull and 1.5" from the transom because both my Pursuits like to ride on the last 3" of the hull so they have to be installed close to the transom

and before I remove them for pickups I know will work well, I even used epoxy to build up little scoops over them just to see what the issue is? and still not enough water to flow! the scoops just caused obvious drag as expected and chine walking .

Im sure others have got them to work but not for me? I have a piece of packing tape over them now so the boat doesn't leak but I need to fill them in with epoxy....grrrrrrrr

That's too bad they've been so problematic on your Pursuit. I haven't used them myself on a V-bottom, but have had good results on the cats.

I hoped you had a solution

I hoped you had a solution

Did you try grinding the inlets open to the shape of a teardrop. This makes all the difference in the world. I’ll try to get an example pic for you tomorrow. I have had the same issue as you on a new boat until I did this.

20170830_204531.jpgI installed the same pick ups in my Zelos. Cooling doesn't seem to be an issue. I did a bit of filing to open up the water inlets. Hopefully, this will solve your issues.

[MadProps]

yes I did dremel them open and even made scoops which didnt help...Im wondering if the V hull plays into this?

any one used thru hull pickups on a v mono hull like the Pursuit? very curious..

sorry about cross posting I will start a thread
