Re: Shadoobie, Shattered Shattered

10 gallons of premium in my empty AV Gas jugs SG were you going to run this in your 540? If needed yes, idle back on premium or get out and swim, I'll take the gas. The Pacemaker on the Shattered boat is wired with a switch to drop timing and it will run on CM gas. Ultimately it was insurance we di...

Re: Shadoobie, Shattered Shattered

This hull is running straight steelflex 2000, no poly. Poly probably would not have stopped the hull from cracking, but it would have limited it to an area we could have patched with my one roll of tape. A couple of views from underneath. The Gorilla glue did a decent job of closing up a lot of the ...

Wow. Is this a 6061 hull?
No, these are hard metal, 7075-T6 hulls, they don't bend, but will break, just like glass. In this case it was like an airbag.

Expect more posts patching a riveted hull :salute:

Re: Shadoobie, Shattered Shattered

So backing up in the story, this is why it is best to run 2 boats minimum when running unfamiliar country. We had some patching materials, but nothing to cover an 8 foot crack. I ran the 16 miles back to the ramp, headed to Lowes and bought $135 worth of stuff as follows: 1 big bottle of Gorilla Glu...

Re: Shadoobie, Shattered Shattered

Initial impact was on the nose, between the center and first T bar to Port. This view is looking from stern towards the bow, Port to the left. It really wasn't all that dramatic because the hull gave way and ripped right down the middle of the T bar runners. No animals were injured in the making of ...

Shadoobie, Shattered Shattered

My son found a long forgotten 8" corner post last weekend, it was sitting about 8" out of the mud, disguised as weeds.

The Stones wrote a song about it.

Joel,

If your gonna stick with what you got, you need to :stirpot: these Caddy boys some more so they spill their secrets, cause it is way easier and cheaper to hot rod a direct drive caddy. It boils down to cam, carb and intake. Big plus, use the prop you already got, just more pitch :cheers:

A riveting kit will set you back $250-$350 for a decent setup. Rivets are cheap enough. 0.100" thick 7075-T6 aluminum is going for $800 a sheet (4' x 12') at the high end right now, it can be gotten for cheaper. You can cut out the bad stuff and patch in good, it just depends on how much needs ...

Knock the rivet heads off on the inside with a chisel, then punch them out. You might oversize the hole with a drill.

Re: Oil Pressure Issue

Diggin, This quote may be useful for your troubleshooting. The oil pressure in most Lycoming engines is taken off the top rear accessory case. The oil pressure fitting has a reduced orifice in the outlet to the gauge. This helps prevent catastrophic oil loss if the oil pressure line or gauge begins ...

If the suction screen was clogged, wouldn't that cause low oil pressure everywhere, not just one port (assuming both gauges are operating correctly)?
Yes, that is correct.

Re: Oil Pressure Issue

When is the last time you pulled the suction screen? fl cracker, That is always a good question to ask, many folks don't realize that there is a suction screen on these engines. Page 2 of my old rebuild thread covers the suction/pickup portion of a SV540 oil circuit. https://southernairboat.com/php...

Re: 454 Stroker for 16 Panther Airboat. Would this be a good option? Repowering.

Casey, My suggestion, without a gear drive you are looking for maximum low end torque (below 3,000 RPM) where the stroker is going to produce the best. The 454 block will also give you the option of a gear drive in the future, which would make a huge difference on performance. As for the Oldsmobile,...

Diggin, There is a reason they came up with terms like Port and Stbd, no ambiguity.

Re: Oil Pressure Issue

Besides, I had to look down and behind me to see the mechanical gauge that was mounted on the engine. This has me doubting the mechanical even more. Plugged directly in it’s going to see all the hydraulic and mechanical vibration. Remote mounting isolates it from both. Turning around to look at gau...
