    3.0LX No Start Problems on New Purchase Boat

    It's a boat I purchased recently with a 3.0LX, and I just got it cranking with a new starter. When I add a little gas to the carb, it backfires a little, but doesn't act like any motor that wants to start. Here's what I've figured out so far: -Plugs look fairly new -firing order is correct...

    3.0 in New Purchase Boat Makes Crazy Loud Noise

    Just purchased a 1997 Bayliner with a 3.0LX. Previous owner says he had the starter replaced last year, and then it started having starter issues. After I got it home, I put in a new battery, and it would make a few clicking noises like it wanted to turn, but wouldn't. It would also seem to lose...

    Drive goes forward, but not reverse.

    Search results didn't help to much. I just replaced the 5.7 motor in my 1989 Arriva. I aligned the motor, and installed the MC-1 drive (pre-alpha) and it likes going forward, but not reverse. In reverse I here some sounds that indicate that it's trying, but failing. Now I'm not 100% sure this...

    Looking for ideas before I discard a half tank of fuel

    My 1989 Arriva purchase this year had a cracked 5.7 Mercruiser block, so I never tried starting it. I purchased a 1986 Celebrity junk boat, 5.7 fired up and ran well before I pulled it. Swapped the motors, and now I can't get the motor to work in the Arriva. When I dribble a little fuel into...

    82' 140 mercruiser sat 2 years, water in oil, any hope?

    1982 Mercruiser 140. Ok, so this guy moved up to Wisconsin from southern Indiana where all he usually did was "pull the freeze plugs and fog." Two years ago he did that up here and the boat has sat ever since. I'm looking at it for him and the engine isn't locked up, so I thought there may be...

    OMC Cobra to Volvo 250?

    I have a nice 86' Larson that has a 4.3L Mercruiser that's shot, and a Cobra outdrive that also needs work. I also have an old 71' Thompson with bad stringers and upholstry, but has a good Volvo inline 6 and 250 outdrive. Besides the controls and motor mount locations, will the volvo engine...

    Dreaded Bayliner L-Drive, repowerable?

    So I can get a free 1990 Bayliner that has already had the busted L-Drive removed and discarded. The hull is in good shape, does anyone think I might be able to do something with this? Maybe some sort of inboard? Anyone have any ideas?

    Wire missing on starter for 1985 AQ131A?

    My starter clicks, but won't crank. I checked my wiring to and from the starter relay, and that seems to be fine. But upon looking at my starter, it only has 2 wires connected to it, the big red one from the battery and the yellow/red one from the relay. There is another spot on the starter...

    86' Volvo 275 Tilt Motor Rebuildible?

    I tested and re-tested the tilt motor out of my volvo penta 275 I/O, and it doesn't do anything when I hook up the 2 wires directly to a battery, either way. Is this motor rebuildible? Are there any kits out there to rebuild it? Anyone here ever done it? Thanks!

    Is this 7.4 to a 5.7 swap a good idea?

    I've got a 1990 Arriva 2450 with a Mercruiser 7.4L in it that is most likely shot (double checking this week). It's coupled to a Bravo III drive. I know a guy who wants the drive and engine, so would it be fine to swap in a 5.7 Mag that I know of with an alpha drive? I think the alpha and...

    How many fuel pumps does my Inline 6 have?

    Looking at the fuel lines, it would seem that there are two fuel pumps on my 1972 140hp inline 6. Does that seem right?

    Which carbs to use on my 1972 140 inline six?

    I have a 1972 Inline six that I'm working on getting started. The carbs that are on the motor right now have been sitting for years and leak a little gas when I pump the gas line bulb. Time for a rebuild, right? So I also acquired with this motor another set of carbs which I'm assuming are off...

    Is there a way to test the transformer on my Inline Six?

    Ok, I've acquired a 1972 Merc 1400 inline six that was stripped of it's electronics. It came with a bunch of extra parts including several switch boxes, rectifiers, and transformers. Plus I also have a brand new rectifier and a switch box from my 1250 that I know is good. I'm wondering, is...

    68' 125hp Merc, why no power to coil?

    68' Merc, 125hp inline six. So my coil wasn't getting anything from the control box, and I ordered a used one off of ebay. I'm wondering if this one is bad too, because I'm still not getting any voltage to my coil from the control box. I should notice some sort of voltage on my test meter when...

    Can I temporarily bypass the rectifier?

    On my 68' Merc 125hp inline six, I replaced the control box that was damaged when I fried my rectifier (accidentally switched the power cables, knew I should have labled those old things). I haven't recieved my new rectifier in the mail yet, is there a way to safely bypass the rectifier today...

    Rectifier bad?

    Am I doing something wrong? Or is my rectifier bad? I followed the directions on here http://forums.iboats.com/showthread.php?t=190638 and I can't get any sort of reading on this rectifier, no matter how I put the leads from my multimeters. I have two different multimeters, and I get nothing...

    Merc 1972 140hp Inline Six lower unit compatible with 1968 125 inline six?

    Hi, here's the story. I have a Mercury 1968 125hp inline six that I was hoping to put power trim on, and what I found is a 1972 140hp inline six Merc that needs a lower unit. It has trim on it already so..... question is will my lower unit from the 125 work on the 140?

My battery is full and I'm getting 12.65 volts to the battery side of the solonoid. And when I run a test light to either of the small posts on the solonoid, the test light...
