    To fuel filter or not. 3.0

    Yeah, running lean isn't the cause of cylinder scoring.

    2.00 ratio Alpha one gen 2

    How much boating experience do you have? There are *plenty* of unmodified "pre alphas" out there. Granted, most of them are MC-1s, but really no need to be ambiguous on purpose. Iron dukes were ubiquitous and durable. They were also never used in a marine application and aren't the same as your...

    To fuel filter or not. 3.0

    Yes, until it gets saturated Most/all newer Merc engines came with the screw on filter I believe. I think we're done with this ... Either use it or don't. There has never been a post here --ever-- where someone has added a filter and had problems. Do what you will with that.

    4.3L MPI 2007 Searay Sport 185. Single Alarm at 20 RPMs and higher

    Is there a way to tell whether the pcm is in guardian mode, vs just running poorly?

    4.3L MPI 2007 Searay Sport 185. Single Alarm at 20 RPMs and higher

    @alldodge , Is the water pressure switch a simple open/closed 2 wire or is it a 3 wire switch? Should be able to test either way before replacing. Can someone post a wiring diagram (or point me to the correct manual--newest I have for a 4.3 is #25, dunno if it covers this system).

    Perhaps start first, then disconnect.

    Tachometer Bad?

    And how loaded the boat is, and what prop you have on there. Trim gauge is most useless.

    Blowby through vent tube? Mercruiser 3.7

    I think that's oil rather than a rich condition. But oil is getting in all 4 cylinders, so running lean -->tuliping a valve doesn't seem likely. But don't see why oil past the rings would cause low compression in one cylinder.

    Head with no holding tank, is this illegal?

    The tuna would be more surprised than you if they found themselves there.

    Outdrive leaking. Can I DIY reseal?

    Lots of good info in the stickies. https://forums.iboats.com/threads/drive-leaking-oil.695163/

    Small amount of water in gear oil.

    Also, keep your eyes open for a spare drive. Maybe not at this time of year, but I'm my neck of the woods you can find them on a junker boat or stand alone for a few hundred. Real nice not worrying about downtime due to drive issues.

    want to run my engine out of the boat.

    True. There isn't any electrical reason to single out a terminal block with isolated positives as being more of a spark hazard than say, the exposed positives on the starter? Or the alt? Or the slave, or...?

    A couple of quick Edelbrock ?'s

    Yeah, first pump was like 7.5 psi, next 2 replacements were 2.5. Though never had a problem running out of fuel once I got the jetting more or less sorted (going to tune some more once things are back to normal-ish). I think that every time I had flooding issues except once was after I pulled...
