Re: Unloading airboat

I tried Polly on mine, felt it added to much friction and was difficult to get off. I switched to carpeted bunks, and sprayed them down with silicone. Slides pretty easy now jamming the brakes in reverse. Cannot just ush it off by hand. Dry loading is not an issue. My trailer is a drop axle with rol...

Re: Asking for opinions here

Totally new to airboats, but have been working on cars and engines most of my life. My opinion is fuel injection all the way. You invest more up front in both money, and setup time, but once they are tuned correctly you have little issues. True tuning is an art, part of the initial investment should...

Re: Help Staying on plane. LS2 6.0, rotator 2.37, 80" Sensinich R

SOLUTION FOUND. HAHAHAHAHA!!! Funny how simple things are sometimes......so I go out this afternoon with a plan. Add 2 degrees of pitch and see how she does. Not gonna lie, had some fears and worries about having to reinvent the wheel if this did not work. Anyway I upped the pitch 2 degrees as plann...

Re: Help Staying on plane. LS2 6.0, rotator 2.37, 80" Sensinich R

All good info. I plan on changing the pitch this weekend to see what she does. Everything above are great options, other than changing the hull. I may build another boat in the future with a wider hull, but this is one is sentimental to me. Pitch first, then I'll update yall. If I end up changing ra...

Re: Help Staying on plane. LS2 6.0, rotator 2.37, 80" Sensinich R

High all, Thanks for the feed back. One bfc I agree with your hp assessment. 500 - 600 is just an estimate from an experienced tuner that has plenty if experience with dyno testing and similar setups. But absolutely, his numbers were in 6k rpm range. (And I never saw the printouts myself) Never real...

Hi all! Thanks, largely to contributors on this site, I have officially been able to begin water trials in my rig.

Re: Engine Coolant Burp

As for filling and bleeding your cooling system get you one of these Airlift Cooling system bleeders. They are a little cumbersome to use your first time but simple. You need an air compressor to use it. Watch a couple videos on you tube, they are amazing. (See pic) I work at a Chevrolet service dep...

Re: Prop VS Motor: Airgator, LS2 6.0, Sensenich NEED ADVICE

Hi All, it took me a while but I corrected the fuel pressure issue. Thought I might wrap out this thread with my final fix. I did indeed have a pressure problem and failed pump which I corrected by switching to an in tank fuel pump. I used the same bosch 044 style pump, and with some help, fabricate...

Hi All, I have an old airgator with t bar stringers. I am curious how you all are mounting your bilge pumps in an aluminum hull. Are you drilling into the bottom? Making brackets for the t bars? Just looking for some thoughts. I already have polly so, another 2-3 holes thought the bottom really isn'...

Re: Prop VS Motor: Airgator, LS2 6.0, Sensenich NEED ADVICE

I think I'm gonna change the pick up to a bottom feed do the pump can be gravity fed, as it was designed. The lift pump just seems like an additional item that may give me issues later. But if bbn the gravity system doesn't work out like I have it planned, I'll have to try one I suppose. This will t...

Re: Prop VS Motor: Airgator, LS2 6.0, Sensenich NEED ADVICE

Oops, just realized I had the flow rate of the Bosch 044 way off. It actually has around a 53gph flow rate. Couple that with the article Onebfc just linked, and it puts me right in the ball park. Also puts me in the ball park of using the 50gpg lift pump. I however though think I'm gonna try to do g...

Oops, I made a mistake on the flow rate of the Bosch 044. It actually is 52 gph pump. Have no idea where I got the 86 gph figure, must have hit the calculator wrong. Per your article Onebfc, i am showing to need about 45 gph, meaning that the bosch should be adequate for my rig, as we believe it to ...

Re: Prop VS Motor: Airgator, LS2 6.0, Sensenich NEED ADVICE

Vents are good. And fuel pressure is erratic, but like you indicate under load it is most noticable. I believe with my current set up I need to try lift pump. However I am concerned that most of the "lift" pumps I am finding are similar still in line pumps like the Bosch. I did find a face...

This go round however we had erratic fuel pressure, and the pump is not sounding healthy. My fuel sys...

I have it angled down sort of in an attempt to keep rain water from dripping into the engine. The filter is a cone type oil bath, though not...

Re: Headlamp issues

Bad connections can cause excessive resistance just like a bad socket would. I would run a new socket with independent power and ground direct to the battery or a fuse panel. Clean all connections with contact cleaner and apply dielectric grease prior to reconnecting. It wouldn't hurt to check the v...

Funny you mention that carmotorbarge. My tuning guy uses a wideband sensor to check af ratio and adjust the tune. We found exhaust leaks at the mufflers and suspect it may have skewed the results enough that the fuel trims are way misadjusted. We are going to run it again now that we have the leaks ...

Re: Broken bolt stuck in prop hub

Just my 2 cents if you haven't corrected this already. I agree with the air hammer and penetrating lube. I would however recommend using an automotive air hammer. They are typically larger, and not the little ones with the spring type Chuck that often come in tool kits included with air compressors,...
