The attached pic, shows a different story(pic 1).

Since I know the installer set TDC to the long line and the motor seems to not be 180 out, I guess I need to put a timing light on it(or set to ear, considering Pat's comments).

I also realize I need to find a way to make sure TDC is TDC. I'll figure something out.

Also looking at internet pics of other factory balancers(which this one appears to be). I noticed the long timing mark appears to match most other pictures found. The mark is in the same spot, relative to the four holes in the side of balancer(pic 2). So likely timing marks not slipping, due to bad balancer.

So seems the motor is to far out of time or the 850 is just to big.

Though on initial startup the cam was big enough to draw water back into the motor. I had to change exhaust to "thur hall". The cam overlap sucked water back into motor, because factory exhaust was routed into the water, though outdrive. New exhaust exits rear of boat into air and corrected that problem. So with such a cam and considering boats typically run higher RPM's. The carb such be right on.

Guess maybe a leak at the base of carb should be considered also.

Know more tomorrow evening, as I will be messing with it. Thanks again guys. I know this isnt really a boat forum. I appreciate the advise anyways!
yep i know all about the EX running threw the prop . many time s the flap valves would come apart .many times you would see parts of them when you did a stren drive R&R look like the heel of a shoe... we did not see it ....more to the point did not want that job on some boats and was a winter job. it was not fun .but did not rate as hi on the list as a gimbal housing that bolt threw the transom i did drink abit back then. some of the work really did suck . that job was not much fun
