water is coming out port motor one side of dry exhaust , also water in oil manfold gasket look good,gil exhaust looks good not tested help ///////?????

Either a head gasket is popped or a cracked block is my guess. I popped a head gasket once and it filled the oil with water. Did you winterize it properly last time. Did this just start? If it just started, I would guess head gasket.

motors been runing fine,put 25 hrs on so far this year spark plugs look good.going to test exhaust tom.

intake gasket puked,instead of water running out through exhaust on the side with no water its puking into the enging..

iron heads? salt water? raw water cooling? the head has probably rotted through. it rots into exhaust passage. weak link with big blocks. in the sportfish world, there are NO raw water big blocks. i am really surprised how few closed cooling systems there are in the go-fast world...

I just had the same issue, the valve guides were all rotted out. Pull your heads and have new exhuast valve guides pressed in. Cost was $120.00 at the machine shop. Here is a picture of one of my better ones. Note- I was told the engines I bought (from a OSO memeber) were fresh water use, that was a flat out lie, but thats a whole other story!

first intake is good motors 125 hrs ,run in salt never left in flush every time ,test exhaust press,no lleaks,head coming off today ///////

Heads are alum 125 hrs on them,

Do you have an inline oil cooler? That would do it.

yes on back of motor
