My hallett bubble deck project that I am building. I am new to posting stuff so I hope everything looks ok. I will post more pics and details soon. But for now the boat is a hallett bubble deck. Motor is 600 hp big block Chevy. Full set back jet. All new wood in boat. New transom, stringers, bulk heads, gunnel supports. All new gel top and bottom. The boat will not be perfect but I am doing all the work myself.
-
Prep for stringers
-
Stringers in and sub floor in.
-
Machined intake for shoe and ride plate. Make bulkhead and gunnel supports
-
Some details on the glass work. All the wood is totally wrapped in glass. I am using 18/08 biaxiel fiberglass on everything. I am sure it?s overkill but I would rather it be overkill then underkill. All my materials are from sherfab in Ontario.
-
Started building my seats. 1/8? 5052 aluminum. Pretty solid seats and light weight and won?t rot.
-
I set the intake. It is at 4.5 degree off the keel and the mouth of the shoe is 1? behind the transom. Some will say it?s too far out but some will like it. Flipped the boat to start working the bottom
-
The boat bottom is getting a full detail. I removed the hook. And flattened out the low spots. I have been talking to Todd Griggs and Chris starkweather. Those two guys know a lot about how to make a jet bot go fast.
-
The wood and glasswork is clean!! Stoked to see the rest of the build come together.
-
The original center lifting strakes ended in front of the jet. When I moved the jet back the strakes were too far away. So I extended them out to the transom like a gullwing. It should give the boat more lift. It might work, it might not work. If it doesn?t work I will have to grind them back off.
-
While the boat was upside down I figured what better time then now to fit the trailer. So I bought a trailer and modified it to fit.I added 2 cross members to the trailer and refit the bunks. And polished up the old chrome rims.
-
Got an old dominator bowl and had it detailed by Chris starkweather.
-
Bottom work is done and ready for gel coat.
-
Got the white gel coat on. Gel coat is a new process to me. It?s a little more difficult than paint. But it came out nice.
-
Got some red and blue and cut and buffed the bottom. It was a lot of work but I am happy with it.
-
The boat of flipped back over and sitting on the trailer
-
Jet is mocked up and transom plates are almost done.
-
Transom plates are done and engine plates are being machined.
-
Mocked up engine. Just waiting on engine plates
-
Engine plates are mounted and started mocking up the exhaust.
-
I left room to move the engine forward 3? so if I have a handling issue due to the lifting strakes, I can try moving the engine first before I grind the strakes off.
-
I?m kinda in no man?s land with this boat. I?m just now sure how to set it up so I have to give it plenty of room for adjustment.
-
Got the y pipe built off the back of the lightning headers. I kinda stole/ copied the idea from nick at mad skills fab.
-
Ride plate and shims built. Set the Engle to 4 degrees up off keel as a starting point. Also built ride plate stiffeners.
-
Getting my engine out back together. Also this is a great tool. The engine is a 489 with 10.3:1 compression. Gm iron heads from a chevelle super sport. 2.25 intake valve/ 1.88 exhaust valve. Heads are ported as much as possible. Everyone told me not to waste my time with these heads but they have been working good. The motor dynoed at 604 hp and pushed my old boat to 80 mph on gps. That boat was heavy. Way heavier then this bubble deck. My cam is 714 lift with 264/272 @.050 on a 108 LSA. This cam is bigger then what I had in the engine when I dynoed it.
-
I am currently prepping the top of the boat( filling in old bolt holes and repairing chips/ scratches.)for gel coat. My seats got powder coated and are off getting upholstered right now. I should get the seats back in the next week or so. I will post pics as soon as I make more progress. I have had the bot for 10 months. My plan is to have it on the water Memorial Day 2023.
-
I have a video of my motor running on a run stand on my instagram page kpclarke86.
-
So awesome that you're doing all the work yourself! Where did you find the boat at? How long have you had it?
Great job so far, keep the updates coming!

I got the boat from a guy in Perris. It didn?t have a trailer because it was stolen, so it was just a boat sitting in the dirt. I got the boat in April 2022 while my wife was on maternity leave. She was so happy for the new addition.
-
Very nice

I'm almost 100% positive, I owned that boat for a few years. Had every intention to rebuild it, but turned into too much of a project for me. Boat and build looks great! Shoot me a dm and I can give you a little back story.
-
I can shoot you some before pics also.
-
So one of the old owners of my boat contacted me (sevans01) and sent me a bunch of pics of the bot before I got my hands on it.
-
More before pictures
-
Built my tail pipe. It will bolt into the top of my transom plate right above the jet. It is built out of stainless steel. Not too bad for a washed up construction worker
-
Here is the tail pipe mounted in the transom plate
-
Filled in all the old holes on the inside of the gunnel. Filled in the old fuel filler hole, steering wheel hole( it was not centered with the seats), forward/reverse lever hole. Lots of very tedious work. I am trying to blend it all so you don?t see the repair after I gel it.
-
This is the filler I have used on this boat and my last boat. I have had good luck with it so far. I can buy it at the local paint supply store( Temecula valley paint). The boat is pretty much prepped for gel. I have a little more sanding on the inside of the boat but I should be ready by the beginning of next week. I will just have to wait for some warmer weather to spray.
-
Coming along nicely dude! How?d you get b1 to do the pump work? I didn?t know he was still helping people out

B1 has not worked on my pump yet. He made me a shoe and engine plates. I have been working with Chris on this boat from the beginning. He knows a lot about how to make a boat fast. I guess I am lucky. I know your boat. How long have you had it for?
-
I finally got the interior of the bubble deck done. All the fiberglass work is done and all is sealed. I am by no means a professional. There are definitely flaws but if am happy with how it came out.
-
We?ll done sir? looks great!.

Well the weather has sucked the last few months. I haven?t made much progress on my boat. I finally pulled the cover back this last weekend and started on it again, but we have rain coming again Wednesday and Thursday. So I went to the Upholstry shop today to try to get the guy to get my seats done. He is almost done. He has to add some edging around the edge and make the seat cushions. But they are close.
-
I also got the motor in. I do plan on putting it on the dyno. But for now I figured I could get the boat wired and plumbed
-
Seats are back from Upholstry. I just picked them up today
-
Suction housing and bowl are double drilled and ready for powder coat.

Very nice

What an epic! Haven't checked in for a while, saw your post and read the entire chain. Looks great! And you chose a hull worth the investment of your time and love. My question is about your seats. I'm impressed you are using aluminum. Never considered Aluminum. I'm needing to replace all the original seats in my '76 Eliminator 18' Bubbledeck which, as you know, is similar to your Hallet. I have two buckets and a bench seat in back, all 70's tuck'n'roll. I'd like to replace the current seating configuration with a "cocktail" configuration....where two front buckets appear molded into the two benches facing each other with a short bulkhead (with cup holders!) in front of the engine. So I am interested in the pro's and cons of the seating decision you made. Do you have the form? In any case, have fun! She's gunna be a Thang 'o Beauty!

ao I built the seat frames with a tape measure and a plasma cutter. I just sized up my boat and my butt and started building. Are you looking for someone to help you build your seats?

Great build thread! Keep going!

This is an incredible thread, so we?ll thought out and detailed

Just found this thread by accident. So inspiring! I have a 75 Hallett Bubble deck I bought in 2021. I've replaced everything but the short block, pump, and hull on it. Looking forward to seeing this one finished.
