No, the gears in the lower unit are cut to rotate in the "other" direction... If the impeller were to rotate opposite - it would mean the engine had to run backwards... and that does not happen.

Mike, why are you needing to remove the screen? Its there to prevent larger particles from entering your engine..if its stopped up, use a pressure washer to CAREFULLY clean it.. other wise leave it there.

Hey Spencer, Its time for a complete carb cleaning and setting by a qualified professional... When you say ran fine out of water.. you DID have the "ear muffs" connected to provide water to cool the engine..?? If you DID NOT.. you MAY have more serious issues. Take this to a qualified pro!!

Hey Janine, The carb(s) is/are stopped up.. they need a complete cleaning and setting... Any qualified professional can handle this job,, - Even a professional two-cycle motorcycle mechanic can do this job)

What is a "arbitrators"??

hey Chaser2 Have you tried to turn it over with the spark plugs removed and in neutral? This sounds "fishy".. remove the cowling... spark plugs OUT... try to turn it over.. see which way the flywheel tries to turn..THEN try turning the engine (KEY OFF/IGN OFF) by using your hand on the flywheel.. DO NOT turn it backwards,,,you will "kill" the water pump impeller.. IF you cannot turn the engine over by using the flywheel. you should be able to "feel' what's happening.. If you feel the pistons or rings are stuck... try liberally spraying some WD40 into the cylinders through the spark plug holes... reinstall the spark plugs and let it sit until tomorrow... If it is still locked up, you can always remove the head and see whats happening.. all you will need is a new gasket... and some Permatex 80064 High Tack Spray-A-Gasket Sealant. DO NOT use any form of silicone sealant - PERIOD!!!!!!!!!! After you have sone all this, reply to me and let me know what you have found... thanks

Hey Peter.. what are you wanting to know.. ?? we need more details to be of any assistance.

Hey Frank, has anything happened to this outboard? It might just be time for new spark plugs..if it is not running well, it might be time for a carb clean and set. ..no biggie.

Which alarm is sounding? Oil or overheating? You need to figure this out first! ... Is the water coming out of the spout high pressure or can you hold your finger over it and stop the flow? If you can stop the flow, you have a bad water pump impeller. If not... you are probably getting good water pressure. If your oil tank is full, the low level sensor is dirty or bad..this will cause the alarm..Fix each of these and repost.

water in the engine crank case oil --major seal or corrosion problem in the motor water in the leg gear box -- pump seal on the drive shaft

Clean your plugs and check injection and linkage. Mike

Try removing a spark plug and make sure you are getting spark. If there is spark put a couple tablespoons of premixed fuel directly into the cylinder before putting the plug back in. It should fire right up, and hopefully will speed up the priming of the fuel system. Hope this is of some help to ya, good luck.

talk with a yamaha outboard service center as generally the oil injection is set to the fuel usage to maintain the correct ratio in the mix

50:1 so 500ml of oil to 25 litres fuel or 100 ml for 5 lts

Google the weight of the stegecraft then the motor, I did this recently so I could work out the weight I would have on my trailer.

there should be a manufacturers plate attached to the hull of the boat with a number of passengers it can carry and the max hp motor allowed to be fitted talk with boat shops as they will know the approximate hp for each make of boat and length while it may be attractive to fit big hp motors to small boats , it in fact makes the boat less sea worthy and makes capsizing easier so get the advice right from the boat shops
