    4.3L intake manifold drain?

    So, went to winterize today (so final compared with the 3.7l!). Wow, glad I removed the petcocks and probed the drains on the block. Not sure the purpose of those except to help sell short blocks in the spring. All took me 30-40 min, could do it easily in half that next time I think. But I...

    Running lean after engine swap

    All from last weekend, a bit chilly today. So it looks like this was the problem. My tach adjustment is weird, and I needed to put the screw between 2 settings. It's now reading consistently 150 rpm high, which I can live with. Also checked my fuel consumption, which was 3.8+ mpg over 85 miles...

    Did you check your compression?

    No spark 4.3 Mercruiser

    That's what the switch does; when it has oil pressure the switch closes and connects the power from the purple wire to the p/y wire.

    No spark 4.3 Mercruiser

    No, that's what it should be doing. Test either how I said or how Rick said. Actually, do mine first to make sure you're getting 12v at the switch.

    No spark plug spark... 170 MC , 1985 Sea Ray

    Not if he doesn't have a spark. Op, not sure what you're testing there. I *think* what you're doing is essentially checking for 12v at the coil (-), which isn't useful, and will get you those results.

    No spark 4.3 Mercruiser

    No, that looks correct on his motor. You should get 12 v from p/y while cranking, starter powers it. When oil pressure rises and you're in the run position, starter no longer supplies voltage. At that point the switch closes and 12v is supplied by purple through the switch to p/y. P/y supplies...

    No spark plug spark... 170 MC , 1985 Sea Ray

    And when you use it wrong it's confusing. Current and voltage are measured differently.

    If it backfired then you have spark, probably at the wrong time. I'm guessing your wires aren't in the right place.

    How can I fix the water leaking at the stern for my boat?

    This guy came on looking for reassurance about a quick fix, found that facts didn't fit what he wanted to hear, and is now going to do a completely half assed fix, ignoring that his boat may be unsafe (but at least he has an auto bilge pump). Op, hope you have your guests sign a waiver before...

    2003 SeaRay 200 Bowrider seized engine????!!!!

    @alldodge , what would have to be done to the ecu to upgrade to a 5.7? Cost?

    No spark 4.3 Mercruiser

    Sounds like op might have the wrong switch. There shouldn't be an acc position. Unless you are doing something outside of factory wiring, nothing should be attached there. Purple is powered in the run position.

    I can't get you to the right link on my phone, but go to http://boatinfo.no/ and look for manual #26. You can find a wiring diagram there

    Do you know what this is? See pic.

    Is the semi circle broken? Maybe a lift eye?

    Crud in carburetor, is it a problem?

    Water in the tank can absolutely do that. Also if that crud in the carb is in the right place, you can be running lean with those symptoms. I'd start by either running off a jerry can and/or disconnecting your fuel line at the carb and run it into a container to see what your gas looks like...

    Outdrive Alignment

    Don't miss the point here that the drive will go on if you force it on, but your alignment will still be off, which can lead to engine coupler failure. I'd be worried that your mechanic is going to focus on just getting the drive on, rather than fixing alignment. In fact, I'd just have him align...
