Figured to start a thread on homemade briggs outboard....

[garzilla]

So.....

I get my mower back from my buddy, and it abruptly broke....hmmmm...LOL

Pawls for the pull start were jacked, so I fixed and got it to work.....redid the throttle to get it to idle down....idles REALLY slow for shifting!!

Just got back from my buddies structural steel shop to chop the snout off the original crank, and to trim up the piece that mates the mower blade to the crankshaft....

Well, that's why he's structural steel....and not a fab shop.....we had a few beers, and he was ready to cowboy this thing apart, and get it mated....problem is, the two pieces are a bit out of true.....as in they weren't totally plumb with eachother when we (he) welded it all up.....using roughly 180 amps at that....WAY too much for what i needed, and that's what probably pulled it out of whack..

What I'm probably going to have to do, is true it up in a lathe....or a "ghetto lathe".....chuck it up in a grinder, and take a file to it to get it true again.

Story of my life....his shop, (dads) didn't want to be a jag....he's wanting to leave to get home, ...yada yada yada.....:redface:

Oh well....pics to follow....

Not sure on the ordering....but one is a JB welded piece that I thought would give me a little stabilizing of the driveshaft...if needed..(it will be if you let a ogre ironworker help)

one is the crank on the driveshaft...one is welded piece, one is installed...pre machining........If done right, you shouldn't need machining...LOL.

This project definitely should work....will it be fast...no, but it should work..

Nice thing is, hopefully, this adapter setup will work with almost any motor...up until the upped the shaft size...it's not pretty, but it should work okay....and like I stated in the other thread....I don't have a nickel into any of this as of now....so....the heck with it..

Naysayers......bafangoo!!!

It's a weekend beer project....WHY NOT!!!????

Re: Figured to start a thread on homemade briggs outboard....

you know briggs sells an outboard engine called "lawnmower on a stick". It comes with a propeller, a quick disconnect gas tank, a kill switch, and all the fancy outboard stuff.

If the powerhead on it blows out then it's just a plain old briggs without the govenor. You just go buy a new powerhead for $125 and bolt it on. No welding required.

They also have places you take your car where THEY actually change your oil for you.......this is simply for sheets and giggles....couple guys on youtube did it with seemingly good success....just giving it a shot myself...if this original motor was worth finding parts for.
..i definitely would have..but coils for an old sears are hard to find and expensive

Wow! After reading this again.....sober.....Ritt.....sorry brother.
I didn't mean to sound like a db....but boy did I.

I just meant that......basically, when I get a fire up my......well, i just have to try and think outside the box and make something work.

This site is nothing but the best!!

well, i just have to try and think outside the box and make something work.

the real problem is thinking outside the 18 pack...well it is for me anyway

Re: Figured to start a thread on homemade briggs outboard....

Definitely my problem too! Lol

I really wish I took more time mating the two pieces together. ...dude that helped me is kinda sloppy and was in a pretty big hurry.....it'll work out though. ..hopefully lol!!

You know what would be really cool?? mount a Tecumseh AV817 on it w/SSI ignition and I bet it would run like screaming hell!

My lower is a shifter though.....so I'm hopefully going to be able to shift mine.

I bypassed all the governor BS and can get it to idle REAL low.....but I've seen his....pretty clean looking setup definitely.
