    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.
  12. 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...

    Re: Tune up for 4.3 merc

    Honestly, you don't really need any help to replace the gimbal housing. It's not a tough job. However, if it were my boat, I would look for a good used drive and just swap the whole shebang. It takes...
  17. Re: 4.3 mercruiser with alpha 1 gen 2. High RPM low power.

    Sure. You shredded the splines on something. You burned up another coupler. Your prop hub failed. You broke the blades off your prop. Um, let's think, what else? Maybe the trailer is still attached?...
  18. Re: Mercruiser 5.7 Horizon MPI with closed cooling and pump to drain exhaust

    The dry joint manifolds are more or less the same as the old style. The cooling water goes in the bottom of the manifold and up through the riser and elbow and out. Your only mod should be in whether...

    I would advise you to remove that lift bracket and either get the correct shaped hose from our hosts or use a bit of Shields Flex II marine wet exhaust hose with proper double clamps (AWAB brand or...
  20. Re: Mercruiser 5.7 Horizon MPI with closed cooling and pump to drain exhaust

    I think the OP means "dry joint" type and not a dry stack.
