Getting my boat out from the winter, I put a new impeller in the water plump but did no replace the base. It has been 6 or 7 years since the base has been replaced. Drain the gear oil and there was no sign of water. Cranked it up and had good water pressure and a strong pee. After letting the engine run for a while I noticed lots of water coming out of the prop. Turned the engine off and saw drips of gear oil mixed with water. Is possible the seal on the base leaked water into the foot and if so could this have caused any damage to the engine.

This has been discussed hundreds of times.-----Running on a hose you will see oil / water emulsion draining out of a 2 stroke motor.---All normal.

I did not mention that I drained the gear oil after all this happened and it had a lot of water. Almost looked creamy

drain and fix tha seal... add new lube, run a few minutes in gear and drain again... check for water (excess amount)... change lube again if none present... run a while and change a final time but keep tabs on it.......

really courious 'bout this... just where would water and oil be able ta "mix" and discharged...or just oil by itself... Tha whole system containing "oil", "water" and or "raw fuel" or completely isolated systems... if oil can get "out" then water can get "in".... now you can get "unburnt" fuel/oil mixture from tha exhaust but certainly not gear oil if all seals are good..... oil or a mix leakin' outta any kinda motor is NOT normal at any time that i know of.....please enlighten me on this.

All normal to see oil water emulsion leaking out of a 2 stroke running on a hose.

believe what ya want but if there's ANYTHING other than water coming out there's a problem.........even if its a water fuel/oil mix.

Must be a reason why 2 strokes are banned in some lakes / areas.------Wish I had a dollar for very time this has been discussed.-----It is normal.

they are banned because of oil/smoke exhaust emissions ....not a "leaky" motor.... thats tha reason for tha "star" ratings in some states.....

that crap ya see in tha exhaust when it happens is usually UNBURNT fuel/oil mixture (unless ya gotta seal/gasket leakin' which isn't right).. not GEAR oil... something is either way fat and/or a cylinder isn't firing or timin' way off...... any thing "leaking" is a problem that ya better deal with period............... its way far from NORMAL... good question ta ask a new mech before ya let 'em work on your stuff.....but like said believe whatever ya want..........

I wish I could enlighten you. I have run the motor on a hose many time and changed the rear oil every year. but never seen this much water. All I wanted to ask can this much water get in the foot from a bad seal in the base of the water plump.

yes, it can... best to pressure up tha case and check it all for leaks though.. when enough water is introduced inta tha case tha oil can be pushed out at its weakest gasket/seal when pressure builds.. ie: tha "orginal" sport master is a prime example of this happining.. when ran hard, it would push oil out from just pressure without tha added water and allow water back in...

Thanks for the reply. I plan to pressure test the foot and the head gaskets for leaks
