I originally purchased this Ultra about 12-13 years ago. I was never totally happy with the way it was set up and planned to re-do everything to my liking.

About 6 years ago, I decided to tear it apart and begin a restoration. Soon after I began, work got busy and decided to shelf the project, buy a running boat and enjoy the river when I could. The boat sat untouched for years.


Here's what she looked like when I finally re-committed myself to the project and pulled the cover.

The tires on the trailer where rotted, flat and the entire trailer was in need of a restoration itself. Since I knew I would be wrenching on the boat, I figured a dolly conversion would suit my needs well.

Eliminator was nice enough to loan me some dollies while I did the conversion so I could store the boat inside.

I lifted the boat off the trailer onto the dollies with the help of a floor jack, a cherry picker and hand full of curse words.

I didn't take very many pictures of the process because I just wanted it to be over with.

Here's some pictures of the trailer resto. I shortened the axles and welded on new spindles to get the tires underneath the trailer. The brakes were removed. They had to be to go to smaller wheels anyways. Fenders N More supplied the fenders. The wheels are golf cart wheels and the tires are DOT rated to 1250 lbs each which is ample. All wiring, lights, bearings and hardware was replaced. Some guys like to change out the leaf springs to get the tires closer together, but I like them spread apart. I believe it tracks better behind the truck.

My friend Matt of MAK Auto helped me out with the fab work. Thanks Matt!

With the fenders off the boat and the orignial steps cut off, it would be a pain to get in/out the boat. Matt and I fabbed up these locking pull out steps. When the boat is stored, they slide back in.

Here's a few pics of it completed.

The trailer was a success and it tows great!

Next step was to get the boat bilge cleaned up. Since I am building all new hardware, a lot of holes wont be used so I wanted to fill them.

Once everything cured, I spent another day coating the bilge. This stuff when on pretty simple with a brush and mini roller. It took 3 coats.

As you saw in a previous picture, it was dirty and hammed. There were a lot of scratches from all the dirt underneath the cover. I took it to Detail Specialties in Lake Havasu. The guys over there spent a few days on it. I was blown away by how good it looked when I picked it up. Before taking it over there, I finished striping the boat.

I installed a new steering rack, cable, billet hub and wheel. I wanted to go to calgo, but couldn't figure out what do do with the steering tube hole in the transom. All the hardware will be powder coated.

The boat is getting more gauges and some of the locations of current gauges are moving so I decided to just rewire the boat.

If anyone is wondering where I got the work cover, DOC's wife made it.

I made some dump bezels out of old stringer washers on the lathe and started assembling the transom and bolting on a few other things I got from powder coat.

I picked up this twin turbo 509 from my friend Dennis. It makes over 900hp. I will be going through it and making a few needed changes.

Boat cleaned up nicely! Trailer mods looks awesome, where will you run it?
Thanks. Primarily on the Colorado River around Bullhead and Needles, but I also plan to get it down to Parker and Blythe.

Got the new IMCO stainless tanks and fills in. I had to take them back to have returns ports put in. Bilge pumps are in and a lot of the wiring has also been finished.

Now it's time to bring the boat back to CA to get the motor plates and other fabricated parts made.




Chris and Joe from B1 Racing have been teaching me a lot of fabrication, machining and jet pump skills. I'm very lucky and grateful for their help. I took the boat over to the shop and we figured out where the motor is going to be and mocked up the plates. After mock up, the plates go in the CNC and then I'll window the rails in the Mill.

I decided to go with bucket seats. They are lighter than the previous seats that were in before and give the cockpit of the boat a little more room. In these pictures the seats are just sitting in the boat so we could figure out how far forward to put the engine.

Here’s some pictures of the rail kit and seat mounts I made that are already powder coated and installed.

Gauges are in.

I made a plate for the ignition box to mount to that bolts to bulkhead in front on the passenger side fuel tank to keep everything out of the sun .

Yes it is very rewarding when it’s “built not bought” I am enjoying the process and I’ll know the boat like the back of my hand.

Transom plates done and suction double drilled.

I don't care for the way the factory hand hole cover doesn't fit the new style Dominator suction flange so started making my own.

Made a foot throttle and linkage, there are holes drilled in the peddle, but don't have a picture of that. This will be a pretty cool one off set up that runs through the stringer.

Modified a bearing cap.

Fuel Pump Mount. Decided on the Magnafuel Quickstar with built in filter. Made it easy to remove base plate to service pump and filter.

Custom made pan from Dan Olson, did a full kick out on the side since I decided on top mount starter. Pan that came with engine was too wide.

IMG_7609.JPG





The oil pick up they made has to be the nicest I've seen.

Pretty much need to get everything back from Powder Coat so I can get the engine in finish wiring and start plumbing. Boat is back at it's home (the river) so I'll be making weekend trips out there to work on it. Thankfully it's air conditioned, because it's starting to get warm out there. LOL

Did you make the though hull fitting with the white insert that fit the black plastic tube? Or buy it?

I bought that steering tube kit from Bob at Dana Marine/ Recycle Performance. It's called the "Detmar Tube" It all came anodized black. I powder coated the transom flanges.

Ride plate, stiffeners and cradle done and ready for coating. I was able to reuse the ride plate, the cradle moved out because of the longer dominator bowl but I used the old holes for the stiffeners. The cradle was a lot of work. Milled the entire bottom 4 degrees and then the edge 9 degrees.

Hoping I got lucky and won’t have to use any shims. Need to bolt it up and check my angle.

Made the front alt bracket and spacers. Need to test fit it all again with a belt then that can also go off to coating. It’s a little difficult with the boat far away but its coming along.

Ending up needing shims for the cradle.

Wiring almost done. Plumbing is laid out. Just need to get around to doing it. Alternator mounted. Need to make a few more things, pull intake to reset and take another run of parts to Embee Powdercoating.




Intake is a Meirsh so I need to modify while it’s out and make a new loader. The loader that was in before was straight up garbage. Here’s example of old (left) next to new.

It’s getting there...

Looks great. I’ve plumbed a couple twin turbo engines so I understand the level of commitment this takes. You running turbo “zoomies”?

Thank you. I laid out the plumbing 3 different times. There is so much and I don't want it to look like a rats nest.
Yes they will be cone shaped and will look somewhat like these. I want them to have that race stainless header look rather than the traditional cones everyone else runs.
