A buddy brought his 25 Yamaha over to be brought back to life after spending 15 years in the basement. I was looking for a stand for it and after rummaging through my scrap pile, here's what I came up with. I used aluminum pipe and angle and welded it, but it would be just as easy to make the 90 with threaded iron pipe and an elbow. I just used aluminum because that's what I had laying around. I bolted a piece of 2x6 to it for the motor to attach to and inserted it into my automotive engine stand. I drilled it to take a bolt through the hole already in the stand to keep it from spinning. Nice thing is it's sturdy enough to pull start and run on the stand.
