    OMC 4.3 V6 dry joint "batwing" conversion exhaust kit

    That's exactly what I was thinking of, there's a 7*, 10*(?) and 14*, after thinking the whole thing though I felt it was less trouble to use what I know would work. Also there's the relative heights of the outlet of the elbow, above the mounting points, there is really no way to know if it would...

    OMC 4.3 V6 dry joint "batwing" conversion exhaust kit

    I thought of that when I converted mine back in 2017, but I thought there could be slight dimensional differences that might cause leaks. So I went with the Barr OMC/Volvo wet joint with the VP 90* down pipes and rubber hoses. Fit fine no leaks…I think I’d have to be able to borrow a...

    My block is drained, right?

    Thinking back I did it that way this year (block drains first) and a lot came out of both sides. To fill it took close to 2 gallons for the block only. Those little picks do help...

    changing from a 2 barrel to a 4 barrel carburetor

    thanks I got it!

    My block is drained, right?

    What I’ve done is open the block drains first, before removing that big hose at the bottom of the water pump, because that shows you if the drain on either side is clogged….

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Eaton's Neck Long Island with the Connecticut coast in the far distance. I don't take the bowrider in LI Sound unless the conditions are perfect. Even with the bow cover on!

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Closest I get to that is Long Island Sound which is between Connecticut and Long Island about 9-12 miles across where I am located.

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I think Lpgc is on rivers in the UK which I'd think is mostly fresh water although not sure of past use of the boat, whereas I am truly in 100% coastal salt water. So when I pull the 'stat housing to check the intake (because just like manifolds and elbows, in salt water they can rust through)...

    I/O (Sterndrive) Conversion to Outboards

    When I did mine years ago it was about 80 degrees out and that stuff expanded like the movie the BLOB. I did it before laying down the deck and cut it flush with a hand saw. Worked out just fine.....still solid 18 years later.

    My block is drained, right?

    I don't think this is your problem but some 4.3s like mine that originally came with the large Delco direct drive starter had a 90* fitting on that side to clear the starter. Not needed with the smaller PMGR starters. Mine still has it because I didn't want to chance breaking it by trying to...

    Strange exhaust behavior during winterizing

    I have the OMC/Volvo style on my 4.3 Cobra (Volvo style manifolds, which is a cold manifold design) and these run at only 145* when on plane and at idle, usually at about 100. I ran the engine at idle for a while and then took the manifolds off to do other maintenance work and did find some...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    You know it's the eternal debate, AF vs simply draining. I do the AF because, I'm a salt water boater and we need all the anti-corrosion help we can get. If in freshwater, and your intake doesn't show flaking rust perhaps draining well is good enough. One thing I will say, my old F/W still has...

    Strange exhaust behavior during winterizing

    Ok for info on the actual solidify temps look on West Marines site. They have a good info page on AFs. From memory both the -50 & -60 start to get solid at about 12 above zero and 5 above zero, respectively, IIRC. In a cast iron engine where there’s no “flex” like plastic pipe you don’t want...

    changing from a 2 barrel to a 4 barrel carburetor

    Those of us with older carbed boats have the collectable car hobby to thank for this, the demand for carb parts and new carbs, has kept this alive far longer than it would have because when EFI came out the 'experts' proclaimed that carbs were now obsolete.

    Strange exhaust behavior during winterizing

    Best thing you can do for yourself, is get and learn how to use, an antifreeze refractometer. Like this... I use this when I mix my own....

    changing from a 2 barrel to a 4 barrel carburetor

    Agree 100%. For people with older boats, a carb is much easier to deal with, because they are all supported in the aftermarket, even the Quadrajet which has not been made since like 1990. And with carbs you have choices, if you have a Quadrajet that's too corroded inside to rebuild, you can...

    99 Volvo 5.0GL

    First pic shows the pick up tube & anti siphon valve second pic is testing them for vacuum leaks…. Vacuum leaks in the pick up tube, anti siphon valve or fuel line can cause this problem as can vacuum leaks at your fuel filter. If you run the boat on a seperate outboard tank you can isolate...

    99 Volvo 5.0GL

    You have a fuel pick up tube and an anti siphon valve. That’s the barbed fitting your fuel line attaches to. There is a spring loaded ball inside that valve. It’s there to shut off fuel flow if the fuel line between the tank & fuel pump leaks so you don’t get a bilge full of gasoline. Make sure...
