Water issues

[Columbia Tom]

I generally change my oil

Dealers are extremely expensive charging by the hour including tons of spare parts to change and charge for a huge after pandemia profit. The OP has received lots of tech answers regarding both escenarios, a matter to check which one applied for that issue to happen. Out of curiosity, after how many run hours while excessively trolling has the crankcase's oil been changed, was it done by an hour meter or head meter LOL!!

I generally change my oil one time a season. using my "head meter"I'd say 100 hrs would be close.

Ok so I did compression test and all seemed good .165psi in each cylinder.Then did a leak down test and didn't seem to have any issues. all cylinders held 28lbs pressure with minimal air leaking from oil filling port..and no real pressure loss on guage.all cylinders acted the same.of I have a water jet issue will either of these tests show this?

Have not stated which of the making oil dilution scenarios stated on post 7 applies to your boating requirements. Have you retorqued with a torque wrench all powerhead's gaskets that deals with watter ?

Yes everything that was visible.

A faulty head or exhaust gasket if having one can account to achieve water intrussion that will accumulate in the oil pan, same as with a car. If the general bolt's retorque went well assuming all the related water gaskets are still in top sealing working condition which isn't known, blame that issue to any of the 3 scenarios mentioned earlier. How old is that motor that's been running in salt water ?

It's a 2000 60 hp 4stroke.hasnt run in saltwater since I have owned it.on yr 5.Iwould think the leak down test would show a bad gasket of any kind.

Check your thermostat.

So it's a 22 year oldie motor which hasn't been used in salt water since you've owned it since the last 5 years, what about the 17 previous years of usage ? With salt motors all water gaskets gets old tends to let mini water droplets inside the motor which will accumulate over time in the oil pan and increase the oil level whereas a motor running with a near shot cylinder gasket detetced thru a leak down test will achieve uneven combustion issues, motor will run like crap. Old and New Head Gasket Comparison :

What I'm pointing out is that water gaskets are not eternal, will work as were intended to work when new and be shot much latter specially if that old...

What is the color & consistency of the supposed water in fuel?

What is the color & consistency of the supposed water in fuel?

I am fairly sure it was water in oil, not water in fuel

 

[lakensea]

Brain fart!

Still would like to know color and consistency.

Thanks.So the motor passed both compression check and leak down test.Filled it with oil and took it out.trolled around for a few hours and it ran like a champ.Have a fuel issue going on I think.motor is cutting out when I try to get up to plane. It comes in and out of it ,by that I mean runs full power and then doesn't but like I said it will run at low speeds for hours.Could it be a bad fuel pump or would it not run at all if the pump was bad?.Also checked the oil when I got home and it didn't show any signs of water in the oil !!.I believe it was a condensation issue after all.

Could you share on steps how to perform compression test? I have the same issue.
TIA.

Bad news.oil is contaminated again..

 

[Columbia Tom]

Going to be looking at head gasket

Well thanks for your advice.This is where I'm at...did oil change, took out for short trip.came back and found oil was completely saturated with water.Decided to go for the head gasket senerio . Got the head off but didn't find any obvious gasket issues..it will get replaced with all the other ones that were exposed.where I didn't see anything real bad on head gasket I'm wondering about the exhaust gasket you mentioned.is there a way for water to mix with the oil through there?where is it?OMG what a job so far and still have to put it back together.shouldnt be bad.

 

[Columbia Tom]

Doesn't seem like it was the problem but it not sure

That top piston looks cleaner than all the rest. If I was a betting man I would say there could have been water intrusion there.
