If you're lucky, there should be a drain plug for the float bowl (the bottom portion of the carburetor). Put a rag or something under the drain plug and then remove the drain plug, letting the gas/water flow out onto the rag. While you're at it, you may want to flush the carburetor with CRC Carburetor Cleaner, or something comparable. Give the cleaner time to evaporate, then put the drain plug back in. (Note: older outboards can have high speed needles where the drain plug should be. You can remove the needle, just make sure when you put it back in, it is in EXACTLY the same configuration it was in before. Also, DO NOT screw the needle in all the way to where it "bottoms out," as this may damage the needle permanently.)
Water in the carburetor is NEVER good, and MAY require you to rebuild your carburetor to make sure that any corrosion/gunk has been thoroughly flushed out.
The 15 horsepower Mercury outboard motor does not have a water pump. The outboard motor is air cooled and does not have a need for circulating water.

Welcome it is a indicator that your water is circulation water correctly
it does not have a waterpump!
It is easy...remove the lower unit..about 5 bolts. If you want to see this done YouTube it...a lot of good videos for DIY.

Depends where the water (ie coolant) intake is
The water pump on an outboard motor is located low down on the skeg. To replace it, you have to remove the lower unit. The impeller water pump is a housing attached to the upper unit, surrounding the shaft. It must be replaced exactly right, so obtaining a proper servicing manual is strongly recommended.
Boat's exhaust systems are located on the middle unit of the Outboard motor, but some of the fumes get in the water.
Raise the motor, get out and push the boat to deeper water.
Take a clean rag and stuff it into the tank - it will soak up the water.
well considering the engine type petrol diesel the best outboard motor to get would be a petrol engine as this is easy fuel to come across just don't get any water in the fuel tank as this will cause the engine to cease and that's bad so get a petrol engined outboard motor and petrol hope this helps
