Have you replaced all three filters under the cowling?
1. Primary Filter (1st one in the Plastic Bowl)
Reference # 12 in "Prim Fuel" Image
2. Screen on the bottom of the Fuel pump-Inside the VST
Reference # 27 in "VST" image
3. Filter between the VST and the HPDI Pump
Reference # 19 in "VST" Image

Number 2 and 3 get overlooked often, and they are pricy, but they do need to be changed.
If that has been done, the problem most likely is in the fuel pumps
Reference # 24 in the "Prim Fuel" image.
The can be tested by removing them from the powerhead, DO NOT remove the fuel lines, just unbolt them from their mounting leaving the fuel lines attached. Then squeeze the primer bulb until firm. If fuel leaks from the center hole on the fuel pump, Replace them both.

Yamaha 20 hp model 2010 petrol mixing with sump oil . problem came quite quickly at least a half litre increase after about 8 hours runing


Could be too much idling,4 strokes like a good run to get rid of fuel in oil,too much pitch on prop can also not allow motor to rev enough

Hi, Anonymous and the usual suspects are:
1. Low coolant level.
2. Restricted radiator air flow.
3. Faulty thermostat.
4. Coolant pump or fans inoperative.
5. Vent hose crimped.
6. Air in the coolant and needs bleeding.

Hi, it needs to have the water pump overhauled and it is not something you should attempt on your own. Take it to someone experienced to have it done correctly. Regards Phil.

Older mecury wont pump water


when you install a new pump it will "cavitate" (pump air) unless you pack it with petroleum jelly.
