    Re: Volvo aq131a water in oil pan

    Yeh the trouble with pontoons is not much reserve bouyancy. Again, your best option is to simply not put the bow up on the bank. I am guessing you do that to make it easy for guests to get on and...

    As you see, if the exhaust is below the waterline, you need to have an anti-siphon loop in the system.

    Re: Volvo aq131a water in oil pan

    If the exhaust system is below the water line, seawater will flow in and fill the exhaust manifold. If there's any overlap, that is, where one or more exhaust valves are slightly open, then of course...

    Re: Volvo aq131a water in oil pan

    Then you should check to see if the top of the exhaust system remains below the water line with the boat beached. If that's the case, then yes there is a clear pathway for water to enter the engine....

    Re: Volvo aq131a water in oil pan

    You might pull the cylinder head off and see if it is merely a bad head gasket, but chances are that the block is cracked. I believe the correct term for the condition of your engine is "toast". They...

    Re: 1977 Mercruiser steering problem

    100 percent no bueno. You might want to get that spare drive as the one you have must be busted. The steering arm is connected to a shaft with splined ends. It is possible that the gimbal ring could...

    Re: 1977 Mercruiser steering problem

    I hate to be a downer but a 45 year old boat is going to be one problem after another. I doubt that the steering will be the end of it nor the least expensive of what will be a series of challenges....

    Re: Trim Fluid Changes

    If it really bothers you, the bottom comes off the pump and you can replace the filter screens and slosh out the black gunk in there.

    Re: Loss of power after 3000-4000 RPM's

    When you are running out of gas under load it suggests a fuel delivery issue. I would suggest that there is an issue with the plumbing from tank to cylinders someplace. If it were my boat, I would...

    Re: Draining bilge often while on the water?

    Your silicone sealing is a pointless exercise. That stuff will fail in a heartbeat. You should use the proper bedding and sealing products. Simply smearing silicone on stuff does nothing.

    Re: Fuel Filter

    Technically there must be a fuel filter downstream of the last fuel pump before the fuel goes to the carb/injectors. The first line of defense is a water separating filter between the tank and the...

    Re: New 8.1 496 Engine overheating!

    My only question is how long the new impeller was in there. Did they do it just before handing it over to you or 4 years ago?

    Re: Draining bilge often while on the water?

    If you don't know when the bellows were done on this, then plan to do them. A couple hundred spent now is cheap insurance against that sinking feeling. Or have an EPIRB on board.

    Sounds like you're doing all you can. Too bad your first go was a disappointment, but at least you caught it early.

    Re: Draining bilge often while on the water?

    I would imagine you have a leak somewhere around the drive. You really should check out any leak that is happening as it can open up at any time without warning and your bilge pump won't keep up.
  18. Re: 4.3 GL-C ran for extended period with raw water hoses installed backwards

    Doubt that you killed it. The oil is going to protect the bottom end and I think you caught it before it did any real damage. Unfortunately the damage that you have done is going to cost many hundred...

    Re: Volvo Penta not idling, idle issue

    Look around for loose/broken hoses and vac lines. Sounds like an air leak. Did you take it apart for any reason lately? If fresh air is leaking in past where the air flow sensor can sense it, it'll...

    Re: Large black hose under fuel pump

    We can only guess without more info like whether it's a 4 6 or 8 cylinder, how old, etc. How about a serial number at the very least. Large hoses are usually cooling system. It may be the seawater...
