Hey there guys I just wanted to chime in here. I have read all of the messages on this discussion. I have been searching for a way to make an outboard out of my old lawn mower engine. I have a 3HP briggs & stratton. I have an old flat bottom jon boat.
Sketch up what you have planned I would love to see it. Do you have a vertical or horizontal crankshaft motor to work with?
Maybe you should start a new thread if you are seriously looking to do this. Wouldnt want to get the prodjects confused by starting a new one in the middle of this one. So start a new Post from scratch, and tell me a little more. how big a boat, weather you want inboard, outboart or something Unique. How much money you have to spend, and what parts you might have on hand.
Finally started some welding tonight, a bit concerned about a few things..
1. my welding is pretty bad hehe
2. the pipe that I am using is galvanized something welded to steel, hopefully these things weld ok
3. my welder is for small hobbies stuff like that so it may not be as deep as it should be.
Anyway I was happy the see a general form start to take place. The link below shows some photos of the progress-double click the small photos to see larger ones...
Looks like your on your way. I think your hobby weilder should be enough to handle it, but I am not the one to give welding advice,, I gorrilla weld myself, but my welds do seem to hold.
From your pictures. The only warning light that went off in my head was about the motor mount.With such a small motor, it might not be a concern, However it appears to me that the weight of the motor will have a good deal of leverage against the transom. All outboards hang over the back, this is true, But they also are much closer to the transom, and in some cases even overhang into the boat some. Your mounting plate looks like it is overhanging the rear too much. The further away from the transom you mount, the more you will amplify any stress created by weight and motor thrust.. I realize its a little late for magor design changes, But I think this could be a Important design flaw you might want too address before you go much further. I bet you have a formula kicking around someplace in your head to figure how much leverage 50 pounds or so will gain at the end of a 1 foot arm. Is there any specific reason it is so far out?
I think I am going to start a new post because we are getting kinding far to the side here...same name outboard motor
