Old Johnson Outboard Repowered With Mower Motor
“The old 35 hp Johnson motor was corroded and wouldn’t start,” recalls Smith. “Water had gotten in, and the cylinder walls were crusted up.”
The outboard shaft, transmission and propeller were still fine. Smith removed the Johnson motor and bolted on an 11 hp Briggs & Stratton.
“I measured the shaft on the engine and the one on the propeller drive and ordered a coupling to match the two,” says Smith. “I did have to modify the throttle and ground out the Briggs & Stratton.”
Smith figures the cost to repair the motor would have been more than $1,000. “My only cost for repowering it was the coupling.”
While the Briggs & Stratton doesn’t have the power of the original motor, it’s enough for Smith. “It pushes the boat along,” he says. “I took it out in the fall, adjusted the carburetor and the throttle, and it worked fine. I can’t wait to get it out this spring.”
