Evinrude 15HP Outboard - Vent Holes

SOURCE: replace water pump impellor 15hp yamaha outboard

Put the motor in neutral.On the leg of the motor there is a little side cover plate.Remove.Undo the bolts.This is the gear change linkage.At the cavitation plate,there is 4 bolts.Remove.If the lower housing does not drop,give it a soft whack with a soft hammer.When dropped,you will see the prop shaft and the gear linkage.Lower it all the way out.Its easy to work on if you put the lower skeg in a vice.Take the water pump apart BUT!!! have a look at which way the impellar blades are pointed.Grease the new impellar as you put it back in and turn it at the same time to get the nodes in properly.Heaps of grease to protect all the bolts.Makes it easier next time.Hope this helps

SOURCE: how to clean boat carburetor

Carburetors are tricky, They have to be completely dismantled, soaked in carb cleaner, make sure all the gunk is off, every jet clean and clear, If you can't get a wire through it, you won't get gas through it, make sure you can blow through it, Get some guitar strings, .009 is about the smallest guitar string you will find, you can buy them separately at the music store if you don't have one. Change the filter in the line, when the carbs go back on, the adj all have to be the same, not one wide open and 2 idleing, Float level is also important, they don't sell complete kits anymore, you have to buy the parts individually, gaskets , etc, good luck.
