A friend of mine is looking for a new hull to replace his old one and asked me to look around for him, the hull he has now is a 16x7 Rivermaster with a DD500. Who makes the best hull, who has the best price, etc? This is now a tire kicker post, he must get a new hull and he will be purchasing...

Im embarrassed to admit it but I discovered why that Cadillac was having cooling issues. Sometimes things are right in front of you and you just don't see them. He had his upper coolant hose run to the bottom of the radiator and the lower coolant hose run to the top of the radiator. It just...

Ok this is another first for me. The friend I helped with the DD Cadillac build pulled the top of the engine down because he though he blew a head gasket on his first river run. After looking at every think we could not find a head gasket issue and had the heads tested again at the original...

I saw this on Houston craigslist and figured it would be something different. A built all Alum Viper V10 engine for $6995. I have never heard of an airboat with a V10 Viper engine, 700# of torque with a 7000rpm red line. https://houston.craigslist.org/pts/5158704360.html...

Ok guys I am missing something and I need some other opions. A friend of mine is building a 500DD boat and I got the new engine fired up for him but something is not right. 500 caddy 30 over 902 heads 10.1 compression MTS dd flat tappet cam, the biggest before roller Alum Edlbrock intake...

I have done a couple of these but I never remember to take any pictures. This weekend a friend asked me to modify His 500 Cadillac intake manifold and this is what the mod looks like. What I did was weld the plenum divided all the way to the top and I welded the exhaust cross over shut so hot...

I have had airboats for many years but I have never used any of the bottom epoxy coatings. All of my airboats have used UHMW on the bottom. The question I have is this, can I put an Epoxy coating on the bottom of my fiberglass 21' Flatscat bay boat? I do not want to flip the boat so im looking...

I am looking at painting the bottom of my Flatscat bay boat with some kind of slick bottom coating like " frog snot, liquid steel, etc " but I don't have much experience with this stuff. My boat runs very shallow and the shells scratch up the bottom, I'm hoping the coating will protect my hull...

This is officially the biggest engine I have done to date. We had a failure of the Starboard engine on our Viking and the so called experts where taking us to the cleaners. We spent close to 60k on this engine before we told them to kick rocks. I called up 540 Mountain Motor and asked if he was...

A friend of mine Just lost his engine over a two dollar part. If you are going to run a manual oil pressure gauge don't run the plastic oil line to the gauge!!!!! Sun eats this line and it will FAIL! If you are going to run this type of line you must cover it so the sun will not kill it. I ran...

Dave I still have the build specs on the LSA engine i did. We have much better dyno pulls since this but I do not have any on my computer. These are rear wheel numbers not crank shaft numbers and this engine is still alive and kicking with no problems at all. On an airboat we could have done...

Can someone please help me with 540 Mountain Motor? This weekend he came to the coast to do a little fishing with me on my airboat and he got so scared he hid under the control seat and I can't get him out now. I tried to assure him that airboats can do more than run shallow swamp water but when...

I know I have not been around much these days but I have had my hands full with the car and replacing the engine in the truck. Let me tell you right now changing from an LLY duramax to an LBZ is no joke! If it was not for 540 I would still be sifting through the wiring harness and tuning on the...

I fought with my Duramax for a month and finally threw my hands in the air. Trust me I went through everything and I can recite the wire colors and plug pin locations from memory. Robert spent two weeks going round and round with my truck and he quickly learned to hate it also. It had several...

I get my oil blended for me and it is the best oil I have ever run, they also sell their own filters and they do a much better job. Be advised that this is not a cheap oil, but you get what you pay for.

Started at 8:00am and had it on the ground by 1pm, talk about a job. Tomorrow I have to swap the internals out on my 5 speed Allison Trans to make it a 6 speed and rebuild the tranfer case. Next weekend I will put it back in and tune the truck with HPtuner. With any luck I will get another...

Duck season is over and I am going to sell my airboat! I just wanted to give you guys a heads up before I listed it for sale. It is 18x8, 2.6 belt reduction, four blade S, 496bbc, front and rear driving controls, 50 gallon fuel cell, dual blue top Optima batteries, dual bilge pumps, lineX...

I replaced my race engine in my car last year. Rebuilt the 496 in the airboat last year. Had the car get hit so bad it cost 34k to fix her and I am still doing rehab for my back. Just when I thought I left my bad 2013 juju behind me I had my Duramax drop a piston on the way back from the coast...

First off I do not have a dog in this race, I do not receive anything from this in any way, I am just passing it along. I have tried many different gas additives in my time but this is the real deal. My self and several of my friends race our Corvettes and we have our laptops hooked up to...

I have a light set up like that sitting in my yard if anyone is interested. I switched over to LED lights
