    Crud and black plugs. Pics below

    Been having a whole bunch of issues with a new refurbed Mercruiser 357 Alpha 5.7L. Engine has less than 20hrs on it. I changed the break in oil at about 15hrs. I posted on the forum because I seemed to be unusally low on oil and had a lot of steam exhaust. Example: add a quart after a few uses...

    Spark plugs and socket wrench Mercruiser 5.7 Alpha 357

    I wanted to check my plugs, but I can't seem to get a fit with a standard car socket wrench. Is there a special kind of wrench/socket for this engine? I had a similar problem with my motorcycle and bought a thin walled socket at the hardware store. No luck on the merc 5.7. Also, does anyone...

    Can't pour gas into Bayliner 2655 Cierra

    I have a '97 Bayliner 2655 Cierra and can only dribble in gas at a snails pace (like 1 hour to fill 30gals slow). There's been some discussion on the topic, which suggests checking the fuel vent (put a new one on) and checking the the pour and vent lines (checked both and were unobstructed). I'm...

    Excessive exhaust Mercruiser 357

    My Bayliner with a 5.7L mercruiser 357 carb is running great right now, but I've noticed it's spouting a lot of exhaust stream on idle (after warmed up). Maybe this is normal? It seems like much more exhaust than I'd expect to see from a truck with a similar engine. The engine is a relatively...

    Reuse gas (that had some water in it)?

    Ok, so i had an issue of some water in my tank, so i pumped it out of my tank and dumped it in a large plastic trash can. I noticed the water settled to the bottom. So if I scoop out the top part of the gas, I should be able to put it back in my boat? My boat is in the water at the marina with...

    Install mechanical fuel pump- mercruiser 357

    I thought this would be an easy job, but I'm tearing my hair out. I have new mechanical fuel pump going on a Mercruiser 357 carb 5.7L. The old one came off very easily. I cant seem to line up the bolt holes in getting the new one on. I feel like I'm missing something obvious. I noticed the...

    Hull window

    Hi folks, I have a '98 Bayliner Cirra 2655. I seem to have an issue that has developed into a problem. My port side hull window cracked. I simply called the Bayliner dealer, described what happened and said they would ship me a new one for $150. I thought all was well until I received the...

    Rail ripped from fiberglass

    As you can see in the photos, the previous owner must have hit something and knocked one of the rail posts out right from the screws in the fiberglass. They tried to fix it but did a sloppy job with some joint compound and silicon. So now I have a small wet spot inside the cabin where the screws...

    waterproof the fiberglass in cabin

    Hi, I have a Bayliner 2655 and with all the rain we've been getting, I've noticed several leaky spots from the top deck down into the cabin areas of the roof. It's not excessive, but it's causing significant mold, and is pretty wet to the touch. There's one area (blackened from mold) that I took...

    1997 Bayliner 5.7 Mercruiser won't start

    Hello, long time reader, first time poster... I just bought a 1997 Bayliner Ciera with a 5.7 Mercruiser last week. All was well and put about 15 hrs on her so far. Today however, I'm bobbing around with the engine off for about 45mins, and when I try to start her up, the ignition turns over like...
