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

    OK thinking about this, it appears that (and someone on the hull truth did suggest this) that the tube that goes from the starboard side exhaust manifold to the intake is some kind of crude EGR system to satisfy some emission standard. So it should be only exhaust gas in that tube running from...

    changing from a 2 barrel to a 4 barrel carburetor

    The Holley is longer than the Q-Jet and slightly wider, the Edelbrock is shorter and a good bit wider on the starboard side. In this pic I hadn't changed the fuel line yet....

    changing from a 2 barrel to a 4 barrel carburetor

    You would need a 4bbl cast iron intake which has the spread bore opening for a quadrajet, both the Holley and Edelbrock are square bore carbs so both require an adapter. There is an Edelbrock aluminum square bore manifold but I recall reading that it won‘t fit with the OMC high mounted...

    changing from a 2 barrel to a 4 barrel carburetor

    The other thing is those one piece batwing exhaust manifolds are pretty restrictive, when I switched to the center riser exhaust (4.0 diameter vs 3.5) the engine definitely seemed more responsive. I would try dropping your pitch 2” first. I run a 15x17 on mine.

    Is this engine oil good?

    Anything sold only on Amazon that’s engine related is immediately suspect to me. So they put the specs but don’t say they meet or exceed them unless that’s on their website. There are a number of alternatives you can find the Merc/Quicksilver oil anywhere really, or you can use a 20/50 from the...

    changing from a 2 barrel to a 4 barrel carburetor

    It was a factory option…the 2bbl was rated at 175 hp and the 4bbl was rated at 205 hp. The thing is that they used a Quadrajet which is a good carb but the originals are all old now. So your choices if you’d want a new carb are a Holley 4160 or the Edelbrock 1409. Used 4 bbl intakes do pop up on...

    New Stuff on Vehicles likes/dislikes

    cars/boats with points ignition could start and run with a pretty weak battery, with EFI, the computer won't turn on! in fact when I had a sticky starter solenoid on my 1965 VW Bug (6 volt) 1200 cc 40 hp, here's how I used to start it... got a spark plug socket, put it onto a long handled...

    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!

    I/O (Sterndrive) Conversion to Outboards

    Great work Ted, love watching the progression of your projects! And when you're done you will have the exact boat you wanted! You got me to thinking, could I get a pod for my old F/W, and go with a 175-200 hp 4 stroke....nah....boat's too old....but would be nice.....and after all many of...

    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...

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

    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!
