    Mercruiser 5.0 MPI 2013. Crank but no start.

    Curious in how you figured this out? Last post indicated that you were getting spark and power to the fuel injectors?

    3.7 L 170 188 190 224ci mercruiser

    Yes, edelbrock 1409. Still don't have it right...

    Understanding Merc Manifolds 3.7

    Can't remember off the top of my head what mine looked like, but iirc the gaskets and reservoir are different depending on whether the manifold is cast or aluminum.

    3.7 L 170 188 190 224ci mercruiser

    Agreed. I certainly wouldn't go out of my way to install one, though if I had a good engine already I'd consider it. The 3.7 only made 190hp with the 4bbl carb, which is pretty rare. Either way you're making new mounts. My 4.3 actually burns less fuel then the 3.7. I'm thinking that the 4bbl is...

    3.7 L 170 188 190 224ci mercruiser

    Having just done this, I disagree. All the shortcomings listed are there. I ran the crap out of mine for 12 years without the cam issue. Never blew a hg. Never overheated. Did the alternator fix, which was like $300 and 2 hours. A non issue. The 4.3 is significantly heavier, which makes a big...

    Replace or Repair, where to start?

    Yes, that's it. Parts that I can see look ok, it looked a bit melted in the other pic. Fitting snug is the most important part, and those bolts apparently tend to snap off when you try to remove them. I'd probably give it a shot, recognizing that it might be an issue...

    Replace or Repair, where to start?

    No, still not correct. That plastic tube is a guide only. The actual water tube is copper. Plastic tube isn't necessary. But yes, plenty of other plastic to break/melt.

    Replace or Repair, where to start?

    NO. This is not what I'm talking about, nor what the op is likely looking at. The plastic water tube is a guide only and unrelated to the water pocket cover. The cover is held on with 4 fragile screws. If it's melted, the copper tube won't mate correctly and will suck air. Take a pic looking up...

    Proper Engine Oil Level

    Too much is *not* better than too little (at least it isn't good). You're more likely to do damage running a qt high than rubbing a qt low (though you're probably fine either way)

    Replace or Repair, where to start?

    Look into the upper from the bottom, it's the plastic piece where the copper pipe fits in.

    Merc 4.3l timing question, BTDC mark

    Yeah, he didn't specify. Just so he knows he may or may not need base mode.

    Replace or Repair, where to start?

    Before you put it back together, check out the water pocket cover in the upper. With that overheat it may be melted as well.

    No base timing mode on a TB 4

    Lower gear oil on Alpha One holes sealed

    Those o-rings are $0.50 a pair and available everywhere, so... Maybe the threads are buggered from trying to drill out old plugs. Regardless, if that was the solution, I'd go through the rest of the boat *very* carefully.

    Lower gear oil on Alpha One holes sealed

    Wtaf is going on there? I guess I'd scrape it off and see what's underneath, but damn.

    1986 Mercruiser 470 Starter & Fuel Pump

    Blocks the same, flywheels the same. Only difference that I know of is that the later engines used a slave solenoid. No gotchas that I'm aware of

    1986 Mercruiser 470 Starter & Fuel Pump

    Looks like the starters on eBay have pretty wide applications. I went with an el cheapo in 2012 that was still working in 2019. Imo unless you're going for an oem/brand name starter you have no idea what you're getting. Worth it to me for ¼ the cost, starter is easy enough to get to. They make...

    Osco risers for 470 motors

    The reservoirs for the cast and aluminum manifolds have different Merc part numbers. They also have different manifold to reservoir gaskets, so I'd guess they aren't interchangeable.

    3.0 LX cooling system

    You should check your drive alignment, grease and check your gimbel bearing, coupler, and ujoints while you're in there. Maybe sure your bellows are in good shape and that your shift cable moves smoothly. Never inspect the impeller, just replace it. On a new to you, I'd order the whole impeller...
