You do not have to remove the top plug. Just loosen it enough to allow oil to drain out the bottom. Same with filling, the top plug just has to be loose enough for air to escape as you pump oil in from the bottom. When the oil starts to seep out the top, stop pumping, close the top port screw and then put the bottom screw plug in. With the top port closed there should be enough vacuum created you shouldn't loose more than a few drops while installing the bottom plug. Please do not over fill the gear case, it needs a little air space. Also, try to avoid over pressurizing the gear case while testing, it only takes a couple pounds to identify a leak and not much more to create one. Another thing, change your gear oil in the fall before freeze up. If you store your outboard outside all winter and there is a little water emulsified in the gear oil, it will separate and freeze,, I have seen more than a few cracked gear cases from this alone.

To change fluid,take out the bottom plug;should be a flat head screwdriver fitting place something to catch old fluid under the lower unit,then take out top plug,it should drain right out... then from the bottom... fill the lower unit till fluid starts to come out of the top hole then put bottom plug back in, then top plug back in and your good to go..when you have the plugs out check the seals on the plugs and replace if needed...that will insure no water can get in..as far as the fuel mixture you can google that info

Where is the oil filter located on a 2004 Yamaha outboard two stroke motor


Some links including a video of how to change the filter. In such questions horsepower is useful along with year :>) Oil filters would only be on a 4 stroke though to protect the engine oil. Your two stoke doesn't have filters in the lower unit. There may be a strainer in the two stroke oil tank.

  1. Fuel
    • A common problem with an easy solution, Yamaha boat engine trouble could arise due to inadequate levels of fuel or engine oil. All Yamaha outboards take unleaded gasoline as a main fuel source with a pump octane rating of 86 or higher. The type of engine oil varies according to motor size and can be found in the "Specifications" section of a particular outboard's owner's manual (See Resources).
    Electrical
    • Problems with the electrical system can also prevent a Yamaha outboard's engine from working correctly. Troubleshoot the electrical system, first removing the main fuse that's located underneath the electrical panel on any electric-starting outboard. If the connection at the center of the fuse is broken, it must be replaced by a fuse of the same amperage. The battery should also be removed, cleaned and fully charged when troubleshooting the electrical system.

    Spark Plugs
    • Owners should also remove and inspect the spark plugs during the troubleshooting process. If the insulator tip of any plug is burned, that spark plug should be replaced. The number and type of spark plug depends on the specific outboard. Additionally, owners should ensure that each spark plug gap is set to the width stipulated in the owner's manual (see Resources).

Most likely it does not have a clutch which is common on cheap curved shaft trommers. The only cause for smoke in a 2 cycle engine is the oil you put in the gas.

There are two major differences in 2-cycle engines. There are water cooled and there
are air cooled engines and the oils are entirely different. Water cooled (outboard) engines run at much lower temperatures and at much lower RPM's. It is necessary for outboard oils to burn during the combustion cycle. In this situation the oil turns to smoke so that the oil is not deposited in or on the water. Air cooled engines run at a much higher temperature and must not be used with outboard oils. In an air cooled engine the oil should leave the muffler in liquid form. If the oil turns to smoke it is not able to lubricate the engine and a very undesirable carbon deposit is left behind leading to engine failure or stuck piston rings.

Since a top quality mixing oil will cost $12 or more for a six pack (that comes out to well over $100 a gallon of oil) there is little wonder that so many companies want a piece of that pie. Cheap oils no bargain even if it is free. If the oil says it is for outboards, lawn mowers, string trimmers, and chain saws, they are telling you that they know nothing about 2 cycle engines and only want to take your money.You should choose an oil whose brand is that of an engine manufacturer. Obviously these companies are not in the oil business but they want to make sure that they do not cause warranty claims from an inferior oil. The life of you engine is dependent on choosing a good grade of oil. You should pick an oil that you trust and that you can purchase on a consistent basis. Unlike gasoline, oil does not deteriorate with age. It is better to buy enough to last you a year or two than it is to change brands every time you run out.

The l0ud muffler probably can not be helped unless the muffler is rotted and needs replacing.
