what causes a 125cc motor to smoke and burn oil ? and is it fixable
Motor mounts are not repairable - just replace.
My guess would be that if has gotten moisture in it. Were the oil bottles sealed? Also how old if the oil?
Check your coolant. Typically milky oil is a sign of a bad head gasket.
Milky anti-freeze is usually an indication that motor oil is getting into the cooling system, probably through a bad head gasket or a cracked block or head.
The boat does still go full throtle
Coolant has mixed with the oil. Normally caused by a blown head gasket. This will destroy the engine if not repaired immediately.
Typically, so much heat is generated by the motor because of no oil to lubricate things, that the pistons are literally welded into the cylinders. It might break a connecting rod . . . In any event, the motor will be unusable and probably not fixable as a result.
whenever water is mixed with oil in a crankcase the heat turns the water into a vapor and this allows oil and water to mix and that is the milky looking substance you see... check for cracks or bad gaskets if the motor is water cooled and buy a dryer agent if it's not... it could be just condensation but enough of that will damage your motor real bad... it lowers the viscosity of the oil and that can lead to big problems!
I take it you mean 150K miles The oil pump..... fixable yes..... worth it... thats up to you.
Condensation of moisture mixed with the oil film inside the cap. If oil in oil pan is not "milky" you are ok.
yes it can water can leak into the intake valley and get into your oil resulting in milky oil
