Ok when ears on it and I put it in reverse it turns prop but when I went run it in the bayou won't go into reverse it sounds like its strippe like its not ping into gear all the way makes that grinding gear noise ...how can I go about taking all that apart to check out gear do I have to go through where the prop is r I have to drop the lower unit

You need to revisit adjustment of the shift rod !-----I am convinced that is where the problem is.-------There was no history given on this motor so that is why I mentioned about the lower unit being off !

??? reverse is not used a lot and not at full throttle / high loads.--------Hard to think that it is worn out !-----------Seperate the upper and lower shift rods.------Now push the lower shift rod all the way down.-----Use a block of wood to block the prop.----Try and turn the flywheel.
