Be sure to do your testing under your normal boating conditions and with a good propeller (not bent, cracked, or excessively chipped). You want your RPM's to be within the proper range while at wide open throttle (WOT). For example, if you look at your tachometer at top speed and it is not within the engine's RPM range then that is generally not good. Your engine's RPM range is important in choosing the right propeller for a given application. This engine has power steering and a recoil-type starter.

The bore for this outboard is 1.81 inches and the stroke is 1.65 inches.

The last thing anyone wants to do is not use enough oil and damage their pride and joy. Hopefully, the above answers any questions you may have and gives you a better understanding of what ratio your outboard requires. Oil ratios can be confusing and daunting. Unfortunately, you will foul plugs at this ratio and leave a very impressive smoke plume on engine start up but, outboards that have been rebuilt or reconditioned need this extra oil while the piston rings bed into the bores. Whilst this ratio might see spark plugs fouling with extended use at lower RPM (such as trolling), in my opinion, it provides the best amount of lubrication for your outboard.Ģ5:1 - Mix 200ml of oil per 5ltrs of fuel. This mixture is very rich and is usually recommended for running in brand new two stroke outboards and when running in rebuilt or reconditioned engines. If you have a rebuilt or reconditioned oil injected two stroke outboard (excluding Evinrude ETEC or Mercury Optimax) then you'll just need to add 50:1 to your fuel and let the oil injection system add the rest of the oil to make up the balance to get to 25:1. Most technicians will have their own opinion or view on how long you should run the 25:1 ratio for but, I always recommend between 8 and 10 hours. You can confidently use this ratio for any horse power and just about all year models. Note: For commercial applications Suzuki recommends 50:1.ĥ0:1 - Mix 100ml of oil per 5ltrs of fuel. Recommended by Mercury, Mariner, Tohatsu, Johnson and Evinrude this is my preferred ratio for all outboards including Yamaha and Suzuki.

The result of using this ratio (less oil) is reduced spark plug fouling and less smoke. For older Suzuki outboards, pre-1997, I'd recommend running 50:1 as the information I've provided about is for current model two strokes. Recommended by Yamaha and Suzuki for most of their small two stroke engines up to about 30hp, this ratio requires the least amount of TCW3 two stroke oil. Below I have listed the oil ratios recommended by manufacturers and a few tips based on my experience.ġ00:1 - Mix 50ml of oil per 5ltrs of fuel.

Anyone who owns, or has owned, a two stroke outboard would have asked themselves the question how much oil do I mix with my fuel? 100:1, 50:1 or 25:1? It is one of the most asked questions for those required to pre-mix their oil and fuel together.
