"Hello all, I am new to the board,my name is Don and I am looking for some help with a boat that was given to me.
I have found the firing order on the intake manifold but my question is which piston is #1 and which is #4?Would it be 1,2,3,4 from the back of the boat towards the front or 1,2,3,4 from the fly wheel back.
I am assuming it is from the flywheel back?
Any help would be greatly appreciated.
Thanks,
Don H."
