Johnson 115 hp
by: Randall

I have a 1990 115 hp Johnson and had so much trouble with the oil injection that I removed it and started pre mixing oil and fuel. I installed a small 12volt electric pump near the fuel supply. Wired the pump to ignition switch and turned it on and looked for leaks. Sure enough, the connector at the base of the engine cowling was leaking. Replaced the supply connection and the boat runs super. A leaking connection can cause your problem too.

Bogging down

Check your clamps that are on your gas lines or VRO pump . I had the same problem with my OMC 110. The black plastic clamps were dry rotted and cracking therefore letting it pull air in when I opened the throttle up
