It will also rev out of water in a can full of water i dont know what the problem is. I have cleaned the carb and the motor in and out replaced the plugs, gas line, gas filter, dighfram, gas tank, lowerseals and oil in the lower unit i do not fell or see any binding in the lower unit and i have no idea why it will not rev only in foward?

Full throttle in reverse? Check compression on the rebuild.

 

[zigman23]

compression is good between 123 psi to 138 psi

Next thing would be to check if you have a good strong spark to both cylinders. There are a couple of different types of ignition systems used on those motors. Either a model number or better yet, a picture of the coils and ignition system would help so that the folks on this Forum can give you specific advice.

IF???? It's working in R then there is nothing wrong with the carb or fuel delivery..
No spark is a problem.
The switching the leads just confirms the problem.
Try switching the coils.If it stays on the same after the switch then my first "guess" would be the pack is bad.
Check/ replace the wire connectors on the trigger, stator, coil and pack.
The connectors, some have shrink wrap and the wire can break under the wrap.
Outboard iginition . com Or CDI ignition has test procedures for the motor.
