    Transmission Spewing Water

    When it’s running have you checked all the clamps for your exhaust system? The ones in this pic look loose to me!

    New Engine Replacement - Engine Died and Hydro locked after 5 hrs!?

    I’ve always been curious how much our boat weighs but it’s difficult to find a place with a CAT scale here, I finally found a recycling place local to me that can weigh it, I might bring it over there in the spring to see how much it weighs. The dry weight of this boat was listed at 2650 lbs, I...

    New Engine Replacement - Engine Died and Hydro locked after 5 hrs!?

    Those lights look suspicious the other area you might check is your depth finder transducer, I see extra holes that have been plugged with sealer. I might also email Chapparal customer service and ask them how much above dry weight you could expect a boat to be (allow for that tower and any...

    Sea Ray 180 sig series termite/water in ski locker rot

    And invest in personal protection equipment like 3m respirators, typecast suits gloves and goggles. Grinding fiberglass is bad for your health and so are the resins used in boat reconstruction. You should use 3m respirators with fume cartridges with N95 inserts for working with resins and P100...

    Overheat on 5.0 with SX outdrive

    what the stat housing looks like inside...stat is held in by a rubber ring you have to dig out with a pick....make sure all these passages are open with no old bits of impeller vanes clogging them.

    4.3 omc cobra no start

    Isn't that the Merc combination of a cast aluminum block and cast iron Ford 460 head? with closed cooling because of the alu block? I think you'd be better off with a 4.3 in every way!

    Overheat on 5.0 with SX outdrive

    Agreed since the impeller is down stream of where the flush port is it’s likely it ran hot and wore to the point where it won’t pump adequately. In fact if you find it’s missing vanes I would remove the thermostat housing and look inside and clean out all the passages. It’s even remotely...

    New Engine Replacement - Engine Died and Hydro locked after 5 hrs!?

    Well certainly anything is possible but it’s also possible for inboard exhaust to run hot enough to melt rubber yet for the engine to be at normal temp on the dash gauge. In fact this is why some engines with overheat warning systems have additional temp sensors on the exhaust elbows to warn you...

    Try posting your question up on the Merc I/O forum, I'm sure someone will know.

    New Engine Replacement - Engine Died and Hydro locked after 5 hrs!?

    If you were in Long Island I could send you to the best fiberglass shop around, Raybo Marine in Lindenhurst NY but you will have to find a place local to you and see what they say.

    New Engine Replacement - Engine Died and Hydro locked after 5 hrs!?

    Usually the rubber coated flappers fail from an overheat…not from age per se. With the Volvo I think they sold a tall elbow kit including additional parts (taller exhaust elbows and a Y pipe with taller ends that extend above the water line. Of course this would require pulling the engine to...

    New Engine Replacement - Engine Died and Hydro locked after 5 hrs!?

    You should be able to get the cam specs from the engine builder. What I do not like about those platforms is this, when they are that low it traps water underneath it and that can increase the hydrostatic pressure from the stern wave forcing water up the exhaust. That and it’s in the middle of...

    New Engine Replacement - Engine Died and Hydro locked after 5 hrs!?

    Well if you measured right your elbows are definitely too low and if the boat is holding water somewhere weighing it is the only way to know for sure, or removing fittings on the transom to see if you have water weeping out of them. You have some options but you may need a good ‘glass shop to...

    Saltwater eating my trailers...

    The cold galvanizing stuff really does work I’ve used it on a few spots on the trailer over the years. Both the spray and brush on are good…

    New Engine Replacement - Engine Died and Hydro locked after 5 hrs!?

    Well what I might be tempted to do, if it were my boat is remove that extended swim platform if possible. I have never been a fan of those they add weight in the worst possible place for inboard engines and the weight of the water washing up over it adds weight and leverage on top of that. In...

    New Engine Replacement - Engine Died and Hydro locked after 5 hrs!?

    No in this set up Volvo in their “wisdom” removed the flappers. After watching the vids I would for sure: Get an exhaust flapper and replace the exhaust tube with it, if that fully solves the issue then great but if not you pretty much HAVE TO FIT TALLER ELBOWS no matter what Chapparal or Volvo...

    I/O Characteristics

    The problem with a filter for the cooling system is that once the block/heads have flaking rust it will never stop, it's more or less constant. So any filter will get clogged sooner or later.

    Mercruiser MAG 350 MPI 2005 -No compression on one cylinder

    yep you may need to break out the 1/2 drive electric impact gun, that's how I got mine off and didn't break even one bolt.

    Mercruiser MAG 350 MPI 2005 -No compression on one cylinder

    Yep blown HG can let water in cyls and that will eventually cause valves to stick. If you fix it promptly you might be able to save it. Do not let it sit like that all winter though or you will be buying a reman or new engine in the spring! Had the same problem 5 years ago and wound up...
