Check out this repair and overhaul of this 4.3L V6. The crankshaft was bent due to the rod bearing damage on #3 and #4 rod bearing journals. I sucessfully straightned the crankshaft, wet magged it, and machined it .010/.010. We completely rebuild the engine including the carburetor along with test running it on the bench. I'm told the vessel is a 1996 290 Sea Ray.
