In theory yes you can. As long as the engine will fit in the boat, is waterproofed, and can be rigged to move the boats propeller.
IF car will run when you gas it, could be the idle air control motor
Gas, and What Wiki User said "a motor"
can someone tell me what the gas to oil mixture for a 48 spl Johnson boat motor is please
Gas and a spark are the two necessary things that make a car motor work.
50:1
The gas and the motor or engine.
Because when your car runs out of gas there is no more gas in the fuel lines to run the motor so when you refuel it then start it there is nothing there to keep it running. The gas have to be pumped out of the tank and into the motor.
A hybrid car, operates on a gas motor, and an electric motor, charged by energy given off from the brakes or axles. The gas motor propels the car at the higher r.p.m.s, and the electric motor at the lower ones, because the batteries that power the electric motor aren't nearly as strong as a gas motor so to go faster the gas motor switches on, and you speed up. As you brake, or as the axles turn, the batteries recharge to power the electric motor, and the cycle restarts when you slow down.
You could buy a gas powered RC boat from any hobby stores or even a toy store. Or WalMart, Kmart or even Target. You could get a gas powered RC boat from Radio Shack too.
A car motor works because it has gas and a spark, the two things that make most motors work.
The gas to oil mix ration for the Johnson boat motor is 40:1 for this year and style outboard. Some people might suggest 50:1 but this can cause your motor to gall and may cause you to loose a ring or two.
A motorboat is a power boat. It is a boat that runs on motors. It always has at least one motor (obviously) and does not have any sails. It just runs on the motor(s) which need gas quite often if you use it a lot and it is a smaller boat. If it is large (at least 40ft), it won't need filling up on gas quite as often.
