SOURCE: Missing operators manual for Evinrude 2 hp outboard motor

Your best bet is ebay for a replacement user manual. Take a look around, you will come across one... For the meantime, gas oil ratio should be 50 parts gas to 1 part oil, i.e. 50:1. General care: Dont go full throttle for any length of time. Cruise of 3/4 throttle... Always flush engine after use in saltwater, including washing down exterior. Keep spark plugs in good order and check prop for fishing line wrapped around in near the prop hub. Otherwise, get a yearly service and have them check the water pump and replace as needed, get it tuned etc and gearbox oil changed.

I have an Evinrude 7.5hp outboard motor.Mod# 8RC1A SN# 0178194. What Year of manufd? How to mix fuel & what octane fuel to use & what oil to use? Help me go fishing, thanks.


91 octane rating ( no e-mix fuels ) and proper outboard oil ( not normal engine oil)
outboard oil has a property that allows the oil residue to stick to the metal bits and helps prevent rust
e-mix fuels absorb moisture and and rusts out steel tanks , destroys rubber components and corrodes aluminium components
the model you have is not listed on any 7.5 hp engine from 1950 to 1958
model number starts at 4434 to 7512 to 7525 in 1958
for a better answer , talk with an evinrude service center who should have a chart listing your motor
units with oil injection are 50: 1 ratio and others are 6 gallons to 1 pint of oil which is around 45:1
I would seek advice from an evinrude service center for the correct fuel to oil ratio for your engine
to mix the fuel , put the oil in first then the flow from the bowser will effectively mix it up to start with
then fit the cap on the tank and shake it up yourself

I have a 1998 model E25RMECA I NEED TO KNOW WHAT TYPE GAS TO USE IN IT. AND IF IT IS 2 CYCLE OR 4CYCLE.


I found a mixture of sites for the information
one owner of a 1998 25 hp evinrude says that it is a 2 stroke with a fuel mix ratio of 50:1 as 25:1 is a bit smokey
another site says that the recommended octane fuel rating is 87 although it might run better on 91
best advice is to find an evinrude service dealer and get the right information as the later 25 hp units are etec engine which will be 4 strokes

Evinrude outboards


Johnson and Evinrude carbureted 2-stroke outboards since 1964 require a 50:1 fuel to oil mixture (2%) on engines without an automatic oiling system - 6 gallons of gas to 1 pint of outboard oil.

What is the oil to gas ratio in my 4 horse Evinrude< Model # E4BRHCOB Ser # B101702


50:1 since the late 60's
Too much oil will gum up the rings, smoke too much and foul plugs. Use ONLY major outboard manufacturers oil, Mercury, Yamaha, Johnson/Evinrude TCW-3. They work the best, and no alcohol fuel.

Fuel mix ratio for 1939 evinrude 3.3hp motor


If you use synthetic or newer oils, follow the recommendation of the oil manufacturer.

Being from 1939, a 2 stroke engine would have been designed to run leaded gas and a very unrefined oil that would burn easily in the combustion chamber. Today's gas and oils aren't even close to what they were in 1939.

If you use a synthetic oil, the mfg's recommendation is usually something like 50:1.

In the control box of an evinrude 115 vro v4 is an alarm why does it go off every 15-20 min when the motor running


The warning horn on a V.R.O. system ( variable ratio oilier) warns you of three problems. (1) LOW OIL. means the remote oil tank in the boat is near empty or empty(2) NO OIL. means there is no oil getting to the V.R.O. .problem is, clogged line or the diaphragm in the V.R.O is blown.(3) OVERHEAT. means the engine is overheating. The V.R.O is you lift and pressure pump for fuel and oil. plus it mixes the oil and gas to proper ratio. Three warning, three senders. LOW OIL sender is in the remote oil tank in your boat. NO OIL sender is in the V.R.O.. and the OVERHEAT sender is on one or both cylinder heads of a the engine depending on the year model
