Re: Aluminum Hull Repair/Rebuild

Slidin gator- great run down on the aluminum. John- sounds like you wouldn’t be concerned at all about the cross seam. That greatly cuts the waste on the 7075 sheet and makes the cost much better to stomach. I got the back deck off and realized bottom and sides are actually 0.125 not .100. Seeing th...

Aluminum Hull Repair/Rebuild

Have a 1968 3/4 deck south FL rock boat that we originally bought in '83. Hull is 7x11'. 7075-t6. 0.100 bottom, 0.063 decks. Lot of history and sentimental attachment, hence the efforts to repair not start over. That said. Hull has been sitting 7 years, now trying to ressurect. Have a complete pass ...

Perplexed by Mag ID

Have 0-320 with a mag drop issue. GMAC gave me some input on a previous thread and I Have searched the forum and have a list of leads to go through. This all prompted me to read the bendix manual. So here comes my question. My id plates show my impulse mag is S4LN-21 and my other Mag is S6LN-23. Man...

Re: 0320 blew crank seal

Got seal installed this weekend. Amazed at how easy it is was. Cleaned surfaces 4 times with carb cleaner and let dry 2 hours before install. Haven’t cranked it yet but hopeful.

Re: 0320 blew crank seal

I appreciate everybody’s help. I have solid seal on the way. I got the Dow 737 adhesive that lycoming specs. Is the “right stuff” more dependable??

Re: 0320 blew crank seal

Removed seal. Part # is SL-13792e. Is this supposed to be a split seal or is it broke. Seal came out easily. Had some adhesive on it but could easily chip it off case flange with finger nail. Found solid seal on aircraft spruce part # LW-13792. Is this the same part? This a 150 case. O-320-e2g

Re: Carb rebuild ????

Yeah. I was headed down the wrong road at first thinking it was good to start the engine and let it at least get lubricated. Realized from reading so many posts on the forum that I was going to do more harm than good. Sure sounds like y’all are reiterating that here. That’s why I did the run in per ...

Re: Carb rebuild ????

Pic super helpful. Will try that. I wasn’t sure and tried various places getting readings all over the place. Noticed when trying to get down there on bottom jug that readings were super sensitive to the exhaust. How much difference do u typically see between cht port vs upper spark plug region like...

Re: Broken bolt stuck in prop hub

Any chance you can weld a nut onto the end of the broken bolt shaft. Set nut on end and weld inside nut. That will give you a new head to work with. Used this many times extracting broken bolts on heavy equipment.

Also x2 on reinstalling the other bolts to relieve pressure.

GMAC. Got Carb Parts today. Can't thank you enough. Did engine run-in as per manual (i.e. 200 rmp steps @ 10 min each) and everything seemed to check out except mag drop. Lost 200+ on one mag @1800 and really rough. Going down the list.. plugs, wires, wire contacts in mag, points. Need to run to air...

GMAC76. Thx for the encouragement. Tore it down today. Housing on the pump inlet strainer had a crack in it. Nothing else stood out. Gave it a good cleaning. L/R lines up correct. Had a little crud. Not terrible but I know with carbs in general doesn’t necessarily take much. Blew everything out. Sol...

I’ll start that I’m a newbie to the site. Been submersed in the wealth of information and knowledge here. Being in VA and away from the airboat world of central FL it’s like finding a piece of home. Amazing! I have a fresh build on an 0320 (160) that hasn’t even been in the water yet. Boat had sat f...
