I recently purchased a complete 250 and needed another stand to put it on. So I decided to try out the
Harbor Freight 2000 pound capacity engine stand . I was very pleased. After mounting my engine, I lifted the back of the stand to see if it would tip to one side. It did not. It felt very secure. Also, the extra support staps that extend from the engine mount point keep the engine pointing straight and level.
For comparison, my 292 is on a "T" shapped engine stand made of 6 inch square tubbing. But even with all this strength, the front of the engine sags. Also, I easly knocked my engine over the first time I tried to move it.
So, which ever stand you choose, make sure that it has reinforcement on the upright to prevent engine sag. And make sure it has 4 wheels that are spaced as wide as possible from each other.
