    Ok Merc guys can you shed light on this....

    I was able to read some of the comments in the Facebook thread and the responder felt it was exhaust gas, which also makes sense, perhaps Merc felt that not having the exhaust cross over in the Vortec design would cause poor fuel atomization in cooler temps. Now the fact that pouring water down...

    Need help: Bizarre Bravo III freshwater galvanic corrosion quandry

    Agreed and if the sending unit lasts more than 2 seasons it's a surprise, I lost track of how many times I've replaced it. At least 4.

    Ok Merc guys can you shed light on this....

    I was responding to someone who posted up on the hull truth about water in cyls on a Merc 5.0, the owner found that his intake was leaking apparently from a fitting that has a copper tube that connects the intake to the exhaust elbow. Leaking from the inside of the intake, into the cyls on that...

    Chinese carbs

    I have heard mixed things, if you have a corroded carb and the machine is still good, I guess they are cheap enough to be worth a try. I will say when I saw Sierra selling a Chinese Quadrajet, it made me sick to my stomach! never on my boat! I will go to Holley or Edelbrock first!

    Mercruiser 260 350v8 choke spring? Different clocked positions

    There is an electric choke kit, I think Mike's Carburators and others sold them, keep in mind you want a 12V source that's powered only when the engine is running, if it is powered when you switch on the ignition the choke will come off too soon. Also, an electric choke is more properly called...

    Best way to get to my boat?

    The WB dinghies are really heavy for their size, a kayak might be easier to haul in your vehicle. Where you are there, is this a bay that backs up to the ocean? What kind of tides and winds do you get? No one has lifts where I am, on the North Shore of Long Island, either you have moorings...

    Best way to get to my boat?

    Or can you build a ladder from the lift to the water and keep a dinghy or kayak on the beach to paddle out?

    Best way to get to my boat?

    I keep my boat on a rotating mooring and paddle out in a 8’ Walker Bay dinghy, unless I have paid the boatyard to use their water taxi service that year… Easy way to do it because the mooring is safe in storms like the one we just had BUT you have to deal with bottom paint…

    2012 3.0L TKS runs great with muffs, but slow on lake...

    Glad you got it! Since you have an I/O it's highly advised to keep the anti siphon valve. Yes they can cause trouble but if the fuel line leaks between the tank and the fuel pump and if that fuel line drops below the level of top of the tank the fuel can siphon out of the line into the bilge...

    That’s the fuel pick up tube also called the fuel withdrawal tube. Use penetrating oil, time & patience. Do not force it work it back & forth just a bit spray more penetrating oil, get it to move a bit more etc. Dang aluminum!

    2012 3.0L TKS runs great with muffs, but slow on lake...

    Yes to the question on the anti siphon valve. The ball must move freely and not stick. Be careful removing it. Look inside the hole in the fitting (top part of the fuel pick up tube) it's screwed into, do you see crud in there? If so it should be removed from the tank and cleaned out or...

    2012 3.0L TKS runs great with muffs, but slow on lake...

    two things, the anti-siphon valve can be gummed up with crud inside, the ball can corrode in place but also the part that it screws into (the dip tube or withdrawal tube as it's called) can have a screen on the bottom that can be blocked by crud also. You can rule these out without taking...

    2012 3.0L TKS runs great with muffs, but slow on lake...

    What you can try is to spray the part of the down pipe (below the rubber hose) with silicone, loosen the clamps and spray silicone in the joint between the hose and the exhaust elbow (top curved U shape piece of cast iron) and the hose. Let soak in for a bit. Then try the move the hose up and...

    2012 3.0L TKS runs great with muffs, but slow on lake...

    And getting back to possible exhaust restrictions, it’s easy enough to slide down the rubber exhaust hose and check to see if the exhaust flapper is still in place & moves freely. If it’s missing then it could be blocking the exhaust. All it takes is one overheat in the past. You could also...

    they (OMC) also gave specs for the anti siphon valve and the pick up tube in the tank.

    I'm going to see if there's a fuel pump volume test in my FSM. Curious now.
