ANGELOS airboats

[ANGELO]

I haven't cut back the cover yet, but from the little I could see the original cables were definitely bad. Made some 1g battery cables and replaced and moved the battery switch to a better place. I have some oil lines open so I didn't crank it for long. But it seemed to crank right away, it didn't struggle. The battery might not be charged all the way either. The charge wire wasn't looking to good.
Not a fan of the messy wiring or lack of a fuse block. It's going to get some wiring done sooner rather than later.

Was making good progress. I had the hole done, I just wanted to get it like one turn deeper and the cheap amazon tap snapped.. any ideas to remove? It's 1/16 npt. I had it moving back and forth with vise grips, but there's not really enough for it to grab

 

[Bacho]

That sucks. Carbide drill bit should go through the tap.

 

[cj3a]

I would grind it out. I have also put welding wire in the flutes of the tap and twisted them with pliers.

 

[bdkw1]

Weld nut to it, back out.

 

[ANGELO]

Im going to try to make a extractor from a socket, then weld a nut. its loose enough i was getting it to go back a forth with vise grips, just theres not enough to grab to get it to cut the chip its stuck on.
And its just behind the jug, so i cant really drill it.
if that doesnt work i might just fill it with jb weld or rtv, and make a plate to go over it while leaving the tap in it.
I removed a oil servo from when it was a generator, that was connected to those two holes. so I just was trying to cap it off.

 

[ANGELO]

Got it!

 

[ANGELO]

Anyone know what this is off of? Or how to test it? It's not putting out any power. So idk if it's bad, or just not being told to turn on

 

[ANGELO]

I didn't want to get to deep into the grass and get stuck. Our group left earlier.
We got stuck earlier in the day on some sticky mud but we were with some people. Got stuck right next to the other guy

 

[ANGELO]

We got stuck in that mud on the way back

I don’t recognize that alternator.

One of the wires on that plug shosuld supply the alternator with voltage. The other should power a alternator light. If it has power on the one side and it’s not making voltage, it’s probably bad.

that looks so fun

I found it. It was part of a airtec aircraft to airboat conversation kit. I found a cross reference to a advanced alternator that was just about the same. But the pulley is smaller, I think I should probably find one that's the same sizes as original. The original one wouldn't fit.

All the airboat groups call these clunkenentals, say they always sound like a 5 gallons of bolts being shaken and clunking/rattling/nocking noises are normal unless untill they become not normal... So it was kind of hard to get a idea of what's normal. When I bought it it had a very normal, faint clunk In the center port cylinder. Over the past 10 or so hours it's been slowly getting louder when it's cold. It also got worse after pulling a broke down boat back to the ramp, I think I overheated the cylinders slightly.
When I did a oil change I decided it wasn't a normal clunk.

I think continental engineers sat around deciding how to make removing the intake and exhaust the most pain in the ass as they could..

But it's off now.

Stuck ring, no groves in the wall but it's glazed

 

[ANGELO]

Intake leak right before that cylinder

 

[ANGELO]

For those intake boots, should I do rubber like what's there? Or silicone intercooler boots?

 

[ANGELO]

So I think I read with chrome cylinders, don't assemble with oil on the rings. Does that sound right?
On first start up I probably need to rev it up and let it get to temp then cool. Then next time I run it, run it hard?

thread hijack
Angeno

I was approached by a 11y/o kid this weekend at his birthday party
kid has gotten his hands on a 5hp horz shaft engine (briggs?)

the kid has a swamp on his property , and wants to make a little air boat

is 5hp even enough to get him moving? and how would you source a prop (R/c?)

kid knows I am at the airport all the time and wants a prop, but I'm not thinking that his little motor is going to swing a normal prop

end hijack

I was trying to find a video of this mini one that was for sale but couldn't find it. Found this 7' one though

There's plenty of mini and air johns. You probably need at minimum a 670 predator. Anything less a mud motor is probably better.
My understanding is even with a 670, it's still not fast, running dry or going through thick grass. Those are mostly used by people who spray ponds.

This one has a 212 predator. He was just running a radiators fan lol

When it come to aircraft engines, I’ve always heard to break in, run hard, but keep it cool. In your case, I’m not sure how you keep it cool. Maybe if you get a cool night. Definitely don’t be towing some one.

awesome thanks
I will pass this info along

good kid, he is already rebuilding engines on his own

If it's not clear water he's probably going to be disappointed. Something like this on a John boat would probably work better for him.

sent his dad a message to look into those too

they have a swamp, a clear lake within walking distance, and they have river property that they vacation on that also has access to the lake there that it feeds

knowing this kid, the boat will be cut up three or four times before it is done, its will be good for him
