    4.3 Chevy

    Well honestly, I'm not sure what's going on...long story, but here goes: Back in October, I forgot to put my plug in the boat, wound up getting towed in. Later, engine started and idled fine, but I discovered water in my oil. Took it to a shop, and mechanic immediately diagnosed that my problem...

    4.3 Chevy

    Hypothetically, if I were looking to replace my 4.3 Mercruiser (1999) with a used 4.3 Chevy engine, any tips on what to search for? Particular years to avoid, etc.? I may have a cracked block, cracked head, or hopefully, just a blown head gasket. Thanks!

    Manifold/riser kit

    Eh...ok, "ripped off" is probably a bit harsh...I really hate posting negative stuff online, as there is plenty of that already!

    Thanks for the reply! Kinda figured I was getting ripped off, and you've confirmed it.

    Manifold/riser kit

    So anyone have a ballpark guess on what it should cost to have this kit installed (basically replacing my old manifolds/risers with this new stuff) - parts, hours of labor, etc.? Thanks!

    Using inverter on board

    Anyone know about inverters? Here's the situation: we're going to be in a Christmas boat parade in a couple of weeks in our little 18' bowrider. I was told by one past participant that he uses a 750 watt inverter on his boat and lights up thousands of LEDs on his boat during the parade. That...

    Manifold/riser kit

    While on the subject of these manifolds and risers, I have another, more general question: why do we even have this system wherein the exhaust manifolds are cooled by water? Cars don't need these, so why do we have them on our boats? Do inboards have 'em? Is it a heat ventilation issue?

    Mercruiser 6.2l 300 (2018) fuel oil mixture prior to winterization?

    I'm curious: what is the purpose of this procedure?

    Manifold/riser kit

    Can anyone explain what this "dry joint" vs "non-dry joint" stuff is, and maybe tell me what I might have/need? Thanks!

    Manifold/riser kit

    Thanks for your reply!! Do you have a link to that kit? I went to the Barr Marine site, but can't seem to find it. Is the kit complete? What else might I need?

    Manifold/riser kit

    So a local mechanic is telling me I need a new manifolds and risers kit for my 1999 Merc 4.3 (2bbl). He says mine have the infamous "foghorn" style which Mercruiser used for only 4 years, due to problems from bad design? How much should I be looking at to replace basically my entire exhaust...

    1977 Mark Twain Worth It?

    I don't know...I think it'd be best to keep the vintage look...certainly makes the boat stand out.

    It's one of led lights (blue, in this case) that lights up under water...

    Flooding...

    Ugh! Never mind...doesn't matter - the boatplug led light I had installed keeps the drain tube from being able to come through the garbard fitting, so using the drain tube to drain my oil is no longer an option anyway... :-(

    Thanks for all the suggestions, folks! Anyone know where I can find a replacement plug, one that connects the the chain which is connected to my oil drain tube? I've looked on this site and various others, but can'5 find one. Thanks!

    Hmm...checked the oil and it looks kinda light-colored and seems thin. I assume I got water in the crankcase? Can I just change the oil/filter and be ok, or is my engine n big trouble?

    Flooding...

    Yes, I boat on Lake Allatoona. My starter and trim pump were definitely under water, but my alternator was not (I assume I'm identifying the alternator correctly). I don't have the skills to remove my starter, so I got some of that CRC stuff and sprayed down my alt and trim pump with it. I'll...

    I went this morning and sprayed the starter with WD-40...didn't even think about the trim pump. I'll get some of that CRC stuff and spray them both down. Thanks!

    Flooding...

    Ok, I did an incredibly stupid thing today - forgot to put the drain plug in! Drove the boat about 6 or 7 miles to a restaurant on the lake...stayed in said restaurant about an hour or so...came out to see my boat had ankle-deep water in the floor. That's when I realized that I had forgotten to...

    Antifreeze circulation through engine

    What about the anti-corrosive properties of AF? Would it not help if I started running AF through first, then pull the drain plugs and leave them out. I've been considering doing this... Thanks!
