2 problems

[cowboy74]

Hey all- I just bought a 91 maxum it has an in line 4 cyl 3.0 ltr mercrusier, two problems I have first off got the boat in the garage and there is 8in of ice in it, ice is up to the bottom of the oil filter, do I have problemss??? second the compresion was 150/135/140/150 PSI and it ran in the fall from what I understand. and it had milky oil in the engine I was told that it could be a head gasket. Let me know what you all think. Thanks

Re: 2 problems

Id be melting the ice is what I would do. Youll need to check any and all hoses in the lower bildge are if theres that much water / ice in there after you get the ice melted.

milky oil is no good. It could be a bad head gasket but its hard to tell. Worst case though with that much ice your block may have cracked and youll need to pull the motor and get it replaced.

Welcome to iboats......
If it sat with water in the oil all winter, the engine is junk.....​

+1 to Haut Medoc

If it didn't, just know the number one source of water in a marine engine is a leaking exhaust manifold.

Re: 2 problems

Those compression numbers don't point to a head gasket IMO. I'm guessing that your description is the condition you bought it in and the compression numbers came from the PO (or did you test it recently)? What does the oil look like now? Was the engine winterized better than the interior?

Re: 2 problems

Yea also, did you transport it to the garage with 8in of ice or did you store it with water in it?

If it was transported with ice, expect hull damage.

Re: 2 problems

With that much water/ice, I would be checking the floor and stringers for rott also. Sounds like the PO did not take care of the thing. Boats are to be in the water, not filled with water.

Have a great day,

Rob.

Re: 2 problems

at least have the drive pulled to check for trapped water /ice in the gimbal boot, might have to replace the starter too.

Read the first post. He said he just bought it. Welcome to i Boats Cowboy!

Re: 2 problems

It makes me cringe here in Michigan when I see boats sitting outside all winter uncovered. I'm sure they are equally mechanically maintained too. Makes me wonder? They could spend $30 for a big blue tarp and stake it down good. that would keep most of the Ice and snow off it. I even hate having mine sit out in the rain covered up in the summer time.
Maybe I'm too fussy? I hear people say.......WELL IT'S A BOAT. IT"S MADE TO GET WET. Well my response is it will get wet even when covered if it rains enough. To not take care of an investment is just plain irresponsible.

Re: 2 problems

Hey There,
I do agree to get rid of the Ice and drain the hull thoroughly is a great place to start. How ever the water/ ice got to be that bad is irrelevant, You need to learn how to properly store a boat. Maxum boats are actually pretty well made as far as the fiberglass coverage and sealing, you may be ok unless you notice several expansion cracks upon thawing and draininng the hull. Get to that piont and report your findings.
As for the 2nd problem , lets just hope you didn't run the engine for long before you discovered the water in the oil, OR after! Even though your compression redings arent exactly the same dosent neccesarily mean the head gasket has failed, but on the other hand , if it was me, I'd buy a top-end kit and replace all the gaskets. It's only a 4 cylinder and shouldn't take you more than 1/2 a day to do it right if you have skills. Better safe than sorry. This will allow you to change most of the gaskets that transport water through the engine where it could mix with oil journals. If you hull is crap at this point you may want to think about junking the whole thing or maybe parting out.

Good Luck!

Delta
He just got the boat, the previous owner let it fill with water and freeze.
It also had water in the oil from the previous owner.

Personally, before taking it apart it would help to find out for sure where the water came from, instead of hopeing to find it by dissassembly.

Re: 2 problems

DUH....? Am I missing something here guys. He said he just bought the Boat and towed into the garage? With Ice and snow in it. The previous owner did the damage. The compression tests also had to be from the previous owner ( PO).
He's got to Thaw and drain the Ice and snow out of it before he can do anything with it.

Re: 2 problems

Cowboy never did say where he was from. How about it cowboy??? He obviously is from where it snows and freezes or got the boat from where that happens.

The milky Oil & water in the engine had nothing to do with the Ice and snow in the boat. I just hope the previous owner winterized the motor.

Re: 2 problems

Hey all- Im From IL, I bought the boat from a boys ranch who got it as a donation, the ice and snow must have accumulated over the winter in there yard. They are the ones who did the compresion test and found the milky oil they also winterized at that point from the pics they had on ebay there was no ice or snow in it. They did say that it ran at that time and its how they got the compresion numbers they also said that it shifted fine. Im unsure on if they changed the oil on it though.

Re: 2 problems

Sounds to me like you should have just made a donation to the boys ranch and left the boat alone.
Obviously no one knew what they were doing during the winterization process.

Re: 2 problems

Ok- Ice is gone and there does not appear to be any damage to anything. Engine rotates freely. I did notice that the engine was winterized. My next plan is to change the exhaust manifold gasket. I checked the oil and it seems clean on the dip stick. Im planning on changing the head gasket after the exhaust.

I have also notice a black sooty type of residue all over the engine compartment and kind of coating all that's in it. Any ideas on the black sooty stuff would be great.

Just guessing but the black soot could be an exhaust leak. Why are you planning on changing the Head Gasket? Why not change the exhaust manifold gaskets. Then run the boat and see what you have from there? Also check your SPARK ARRESTER and clean it. The soot could be coming from there if it hasn't been cleaned. It should be cleaned every year. In fact I would clean or at least check that before changing the manifold gaskets.

Re: 2 problems

Where would the leak be coming from I check the elbow, manifold, and everything up to where it leads out, I saw no cracks or holes. Im thinking maybe a smal blockage in the elbow and it back flows into the carb, but the carb is immaculate.

Did you check the filters? Something is blocked/plugged somewhere. That's why I suggested checking the Spark Arrester. On Auto's it's often the PVC Valve plugged. I'm not sure if a Marine Engine has a PVC valve or not. Be patient tomorrow tashasdaddy and/or someone else will be able to give you some Ideas to check.
