I suspect dirty carbs.

Can you keep it running in gear if you use the choke?

You are dropping at least one cylinder, JohnnyO. It will seem fine in Neutral and reverse on one cylinder.

Try spraying fuel mix (NOT starter fluid) into each carb at idle. If the idle picks up that carb is at fault.

Good luck, and welcome to iboats. :)
