The 1991 Johnson 140 hp VRO outboard motor typically weighs around 350 pounds (159 kg). Weight can vary slightly based on specific configurations and optional features, but this is a general estimate for that model. When considering installation and usage, it's important to factor in the weight for proper boat balance and performance.
A 1991 115 hp Johnson VRO outboard motor typically weighs around 330 to 350 pounds (150 to 159 kg). The exact weight can vary slightly depending on specific model variations and configurations. This weight includes the motor itself but does not account for additional accessories or equipment that may be attached.
Fuel ratio is 50:1
more than likely 50 to 1
How much oil do I use per gallon of gas for a 40 HP Johnson motor
This engine should have a VRO pump and if it has been bypassed the mixture is 50:1
'92 Johnson 115s are VROs which will vary fuel"oil ratio if operating properly. At idle, should be the 50:1 std. up to 100:1 at WOT. Some owners bypass oil-side of balky VRO pumps and pre-mix. Pretty bullet-proof motor if no VRO problems and seasonally maintained.
The VRO (Variable Ratio Oil) system is an oil injection system used in some Johnson outboard motors, designed to automatically mix oil with fuel for two-stroke engines. This system adjusts the oil-to-fuel ratio based on the engine's RPM, providing more oil at lower speeds and less at higher speeds, which helps to reduce smoke and improve performance. The VRO system is often praised for its convenience, as it eliminates the need for manual mixing of oil and fuel, but it requires regular maintenance to ensure reliability. Many users opt to bypass the VRO system in favor of pre-mixing for added peace of mind.
The Johnson outboard models equipped with VRO, (varible ratio oiling), have an onboard oil reservoir. Use a good quality, TC-W3 rated, 2 cycle oil. It is also good practice to not mix various brands of oil in the VRO tank, as reactions of additives in certain brands can lead to filter gelling.

If not using the VRO system, a 50:1 ratio is required, this is roughly one pint of 2 cycle oil to six gallons of fuel.
