    Received the second set of valve covers from eBay. These should work being they’re left and right covers! Now I can finally finish up the engine. Hopefully one day this week.

    I finally got the starboard engine back together today. Tomorrow I’ll hopefully have some time and run her. I still want to say that the #1 and #3 injector wires were crossed. I used my scan tool and when I test #1 I can feel that injector pulsing. We’ll see how she runs with the wires that are labeled in the correct positions. I also noticed that there was a water trail dripping on the port risers. I used after market gaskets, last time I do that! Quicksilver gaskets on order, $272.00 !!

    Those are some pricey gaskets

    Thanks @grouch0jr
    @captkevin , it’s crazy! I never bought them separately, they always came with the manifold / riser kit. Must be why I installed the aftermarket ones on the port side when I took it apart.

    Started her up this morning and she’s purring. At first the power steering pump was giving me all sorts of problems and making noise. Since I replaced the steering actuator, all of the air needed to be bled out. Once the air cleared, all good 👍🏻 ⚓️.

    So she ran fine with #1 and #3 injectors wired correctly. Crazy how it ran with them swapped. Don’t know why they were like that .

    How do you think they got swapped?

    The previous owner had the heads replaced on that engine, so I’m guessing whoever installed them wasn’t paying attention.

    Hard to believe it ran that good all this time like that. Boat should be amazing next year with all the work you have done.

    Thanks @captkevin , I agree, at times I did notice that the oil had a slight fuel smell to it, I’m guessing this is why. I wish the season was longer here! Would love to put her back in the water! ⚓️

    Another thing I found interesting was when I put the engine to TDC before I adjusted the valves, the engine was pretty easy to turn over with a socket and that was with the spark plugs in. After the valve adjustment, the engine was very difficult to turn over by hand.

    @aero3113 do you have a pic of the ANL fuse at the starter? I want to replicate the 330/350 starter wiring/fuse setup on my 390.

    @YYZRC , sorry I don’t. Next time I’m in there, I’ll take some pictures for you.

    I removed the risers and elbows on the port engine to clean everything up so I can install the Quicksilver gaskets. I saw a tiny bit of water by 3 and 5 exhaust ports and surface rust. I’m assuming since I saw the gasket leaking on the outside, water got in there also. I got paranoid and pulled the exhaust manifold to clean and look for cracks, with it clean I don’t see any. I even borescoped the 2 cylinders to see if there was any water in them, no water and the spark plugs weren’t rusty. I’m sure it’s from the leaking riser gaskets and I’m just being extra cautious.

    I’m just confused at how there could be water there if it was the gasket since the water ports are separate.

    I would think there has to be a crack somewhere on the manifold 🤷🏻‍♂️.

    The only spot that I saw that looked like it could be a crack was here, but with it cleaned I didn’t see anything. I’m going to let it sit and see if it starts to weep.

    DO NOT BUY after market riser gaskets!! Seems like this is the cause.
