Kind of a broad question: what are you attempting to accomplish? get back to shore? fix the thing? How large is the boat, how large the motor? What materials are at hand to use? If attempting to get to shore and the water is calm, simply go backwards all the way. If not, and such is possible, remove the motor from the transom and clamp it on the side of the boat, you should be able to use reverse to go forward. Really, I think you are going to have to re-write this question.
6 horsepower? That wont make it past 5 mph if that is what you are hoping for, Is it a troller? If it is than that is meant for shallow water with a fishing boat...
Perhaps the spark plug system is not sending electricity to the spark plugs.
Get the air out first..
the motor wont work properly............
Because a paper boat does not have balance to float
Getting power to motor? if so could be a bad motor if not could be bad resistor pack or bad switch
It can be several things. Here are a few simple (cheap) things to check 1. Does the boat have a sub floor that has filled with water? 2. Is the motor trimmed in? 3. Are you using the correct pitch propeller? Once planed does the engine rev to manufacturer's specification? 4. Is the bottom of the boat "bowed" or have a "rocker" as opposed to concaved which would make the boat plow.
Faulty wiring, faulty ignition switch, or possibly a faulty neutral safety switch.
has a full charge won't go forward or reverse
Common causes, blower motor resistor, blower motor, wiring or controls
It's in "reverse."
