Thanks Ridge, thats along the lines of what I was thinking but I wanted to hear it from some one else to confirm it. Do you happen to remember the thread title at Scream and Fly. I may look it up to read it.

Motorcross guys ruthlessly rev their 2-strokes with no load and drop the clutch and go through this cycle over and over. I wonder what the difference is between a 2 stroke bike and a 2 stroke outboard. They obviously know something I don't

just guesing, it might have something to do with the mX motors having the bearings and pins laying in a horizontal plane, and haveing splash oiling to the bearings from teh crank case, whiel OB motors have the bearings laying vertically and having onluy the oil thats induced thru the crank case. Just a thought?

I know the shop I used to work in sold several of the Land & Sea torque shift props. We dialed each one in pretty good(water tested them on the customers boat) before we let the customer have the prop. Every boat(5) we sold one on came back with in 6 months with rod bearing failure, could have been unlucky chance. Our theory was the props were allowing the crank to unload right before it shifts, allowing the rod bearings to chatter. We couldn't prove or disprove without spening a lot of money and breaking some parts, so we figured it would be easier to stop selling the props

How about chain saws, they are like outboards, no oil bath there but they do have a chain attached to them? All in all I am impressed with 2 strokes, I like their design and operation.
