Re: Marty Bray Hulls

Using the Steelflex was to make it slide across the ground with ease. Not to keep the KEVLAR from wearing out. Of course you have to wear the Steelflex off first. Sharp rocks will cut thru the Steelflex but not the KEVLAR. Your bottom will bounce off boulders. KEVLAR is used in Bullet proof vest so ...

Re: Marty Bray Hulls

Marty's hulls have the straightest bottom of any hulls made. They also have the least amount of drag. If you want a hull that want wear out, get him to lay up the bottom with 5 layers of KEVLAR. The bottom will be bullet proof. No polymer needed. Just Steelflex. It will cost more. About 240% more. B...

Re: DualSync Waterline Drive, Update & Video

That is the only one. 13 and 14 foot hulls would set too deep in the water. You could get up with David Wine to get it.

Re: How are the Eco Techs holding up

Hey Duece, racing is not different from airboating. These racers will be turning their engines up to 9000 rpm's and doing it for hours. Their engines live. Most CM airboat engines will die before 7000 rpm's. AC engines want live long past 3500 rpm's.

Try to find someone close to you that has a Ricermaster hull so you can copy the chimes. The Rivermaster hull drives like a Corvette.

Re: Convince me to build a BMW airboat!

We set up a redfish boat with a modified VanGard. About 50 HP. The hull was 16 X 7. The sides were cut down to 12 inches high. This boat would not run dry unless it was wet grass. It did run 28 mph in skinny water. The best part was the draft was 3 inches. It didn't take much to get it on plane. The...

Re: Mini's going to Broward Show

This 10 ft X 5 ft 6 inch hull is a one person boat. I think Marty Bray still sells them for $ 1700.00.
The 2 person, 11 ft X 6 ft 6 inch hull should sell for $ 2000.00.

Re: Is adding dual plugs worth it? 220 GPU?

Dual Mags will not produce any more power than a single mag. With dual mags you must reduce the timing to 25 degrees. Doing this and switching one mag off drops your timing to 20 degrees. This is proven by studying the RATE OF COMBUSTION. It takes longer for the fuel to burn all the way across the c...

Re: New Build EcoTec Turbo 2.4 (First build want advice)

1. I would use a 2.55 OX-Box. Call Brain at 863-581-9710. ( I have the adaptors for $ 375.00. 352-330-1015 )
2. 3 Blade 78 inch Water Walker Maximus.
3. The 14 will be more agile and better in the turns.

Re: Chucks Mini Pro 105 running dry

You can order a hand laid hull from Marty Bray. 386-590-3859. It is 10 foot long and 6 foot 6 inches wide. It is by far the best mini hull made. He lives in Live Oak Florida. ( the bottom of the hull is the single most important part of any boat.)

It is a stock 40. We moved the air filter away from the light air the front of the prop makes and drilled the main well air jets. The complete boat weights in at 500 lbs.

The later harness has an 8 pin MAF with the Barometric Sensor added in. It is not a 3rd Map Sensor. The LHU engine comes with a Manifold ...

Re: Bullfrog Marine

The best made hull is a Marty Bray Rivermaster. All hand laid and no excess resin left in layup. Perfect bottom and chime stops hopping in turns. Still 220.00 per ft but may have a price increase coming due to cost of materials.

The Sensor # should be 12644228. Check with your local GM dealer and make sure that # is a Barometric Pressure Sensor. Some where around 40.00 dollars.

Re: Ecotec 2.0 wireing

Does your Mass Air Flow Sensor have 5 pins or 8 pins? If it has 8 pins the Barometric Pressure Sensor is built into the MAFS. In 2011 the early models were 5 pin and the late models were 8 pin. Mid year change. I will get you a part number.

Re: Ecotec 2.0 wireing

The code P2227 is the Barometric Pressure Sensor A Performance. Make sure this Sensor got reinstalled when the Harness was put on the new engine. This is a 3 pin sensor and does not connect to the engine. Just a bracket on the engine.

T ry taking some pitch out of the prop to get the rpm's to at least 5100. you want need over 5300 rpm. You will see more boost. You will also see better performance at lower rpm's.

Re: Ecotec 2.0 wireing

2. You misunderstood what I said. The MAP and TMAP sensors must be connected. I said don't connect a boost ref. hose to the fuel pressure regulator. Alfa-Fab also had the ECM marked as an LNF instead of LHU and the engine would not run.
