A true homebuilt B.O.B

image.jpg image.jpg image.jpg image.jpg After i run it i will know if any issues pop up. But so far so good. Here is a pic of me chopping the stock pto down to nothing and my hull all painted up. Next is to chop the flywheel up and the engine goes back in!! Ive pulled over 25 pounds off the engine alone. And 18 of that was rotating mass :) And also a pic of the weld job on the bottom end to close up the gear window
 
The counter balance shaft is there to deaden vibration, being that the engine was orginally for a sit down ski. The crank will be fine without it. A unbalanced crank is a unbalanced crank. It will eat bearings with or without a balance shaft. Make sense? All the weight reduction on the rotating assembly should really make this engine weapon. It was already a powerhouse! So im excited to see what this does! Not to mention the amount of weight its shaved off of my ski. Ive shaved about 30 pounds off of the engine. And about 15 off of the ski!!
