No power Mercury fifty classic

I was given the stator by the owner the first one that he gave me was not the right one it was for a 3 cylinder and his motor is a mercury classis 50 he returned it to the dealer and recived one NO 398-832075A14 installed it on the motor turned the ignition key engine and it fired up right a way owner took out the boat for a run said it did not have full power.
On rexemaning the enging I detected a leak on the intake manifold gasket I installa new gasket
I tried to ckeck the timing,I tryed 2 different timing lights none of theme worked
I tryed my timing light on my boat it worked alright
the owner tryed his boat again and telles me there is still no power at high speed

look at the basics spark fuel and compression.

You can get some neat inline spark testers cheap from a auto parts store that way you can run the engine and see the spark.
I use a regular automotive timing lite and it works fine, I wonder if your spark is weak.
