    Thunderbolt V Shift Cutout

    Greetings, I have a 97' Merc 5.7L with a Thunderbolt V ignition and no Knock Control Module. It's been sitting for quite some time. Last time I had it running on the muffs, everything was fine. I went to pop it in gear and the engine died and that was it, it never started again. That makes...

    Mercruiser Thunderbolt IV Coil

    Greetings, I have a 97 Merc 5.7L "new" longblock with a Thunderbolt V ignition with 60 hours on it that won't start. The spark is weak and the coil is out of specs from an ohm meter test per the specs in the Merc manual. The only place to get a coil for a boat on this island is from the NAPA...

    Outdrive leak

    Boat has been sitting since Easter since I've been off the island more than I've been here. The second last time I used it, I had to add about 8 ounces of outdrive gearlube to the reservoir. That's the only time I ever had to add any since replacing the impeller about a year ago. Boat was...

    Alternatives to Bottom Painting

    Couple of questions. First, I had a thread about a year ago regarding attempting to pull the boat every week or so and rinse it off. That won't work as I get barnacles and terrible growth in 1 to 1 1/2 weeks here. Same as I got on Lake Erie in about two months (plus the barnacles of course.)...

    Ramp ettiquete?

    So which ones of you were complaining about someone taking an extra 5 - 10 minutes on the ramp? Tried to float my boat at my marina today and ran into this. Usually there's just cars parked there and you hope they are still at the marina. I was told these guys left in the morning over six...

    Merc 2bbl & Manifold

    Have new 5.7L longblock with original Merc 2bbl & cast manifold. Been having issues with the acceleration from idle since installing the motor 30 hours ago. Motor runs good although plugs are blacker than they should be; (all plugs look identical.) Compression check is between 165 and 174...

    Any? grease is better than no grease at all?

    Well, just got everything bolted back on the boat after replacing the gimbal bearing and impeller. Greased up the gimbal bearing and when I pulled the gun away. . . blue grease? Some idiot, don't know who that would be since I'm the only one here, marked the grease guns wrong. So now my...

    Merc 2bbl to 4bbl conversion

    Kicking around possibly swapping out the stock Merc 2bbl with a 4bbl on my '97 (non vortec) 5.7L Merc. I've seen a lot of folks here stating that the E-1409 carb from Edelbrock works well for this application. Since I have closed cooling, I was also going to replace the cast iron manifold with...

    OMC Outdrive Oil Fill Procedure

    Buddy of mine bought a new "to him" boat with a 5.7L and an OMC outdrive. He's getting ready to winterize it. One question: After you drain oil from the outdrive, do you refill it from the bottom like an Alpha or can you add the oil from the top?

    Online Engine and Outdrive Manuals

    Is there an index for the different engine and outdrive manuals that are online at boatfix? I browsed all over that site and couldn't find even a reference to them.

    Mercruiser Lubricants ***Not another oil thread***

    The Merc manuals have all kinds of special lubricants that are required when reassembling and installing the outdrive but most places don't sell any of them. For the current mini project, I need: * Quicksilver 2-4-C Marine Lubricant with Teflon * Quicksilver Special Lubricant 101 * Engine...

    Thunderbolt V Ignition

    1997 Merc 5.7L 2bbl with Alpha I Gen II and Thunderbolt V ignition with no knock sensor module. Engine is a brand new long block at 29.6 hrs. Timing just doesn't seem to be correct when setting it. Incorrectly thought I had a TBolt IV since there was no knock control module and set timing at...

    Alpha I Gen II growling when turning

    Have a '97 5.7L with an Alpha I behind it pushing a 22' Bayline Express Cruiser. Engine is new. Outdrive sat on back portch for 4 months wrapped in plastic while out of boat. Was supposedly rebuilt 30 hours prior to that. Outdrive hole in transom was also covered with plastic. When running...

    Mfg Comparisons

    A buddy of mine is looking at buying a PWC and I told him I would ask around to see how out of date my infomation is. I sold my pair of SeaDoos back in '98. I liked the hull design of the SeaDoos because you could cut the wheel and spin them out. The Yamahas acted more like a boat and would...

    Dashboard Gelcoat Cracked

    My boat currently has the ugliest dashboard on the planet. Besides needing to repaint the control panel, the entire dash the width of the boat has hairline cracks. They look to be as deep as the gelcoat, but that's all. Also, the entire dash is faded really bad. I heard there's a way to...

    Harmonic Balancer

    Same motor as other posts. New 5.7L longblock. After running around on the water for less than an hour at different speeds (all under 3K rpm), when I got back into the marina and looked over the motor, I noticed the harmonic balancer had a distinct wobble to it. Probably had that before I...

    Mooring cover for 97 2252 Cierra Express

    Hrmm. board ate my last post. Does anyone know who makes a mooring cover that will fit a 1997 Bayliner 2252 Cierra Express cruiser? No one makes a custom cover for the boat. I purchased from a vendor who's specs exactly matched my boat; type, length, width, bow railing height, etc., but the...

    Ignition timing on 5.7L

    Just got my new long block in the boat and got it started. Running the engine on muffs and set the timing by ear and engine sounded real good. Cracking the throttle sounded good. Put the timing light on and found out I was 12 deg btdc. Backed it down to 8 and it doesn't sound nearly as good...

    Running engine without the sterndrive in

    Merc 5.7L with Alpha Gen II drive and closed cooling system. Does anyone know of any reason you couldn't run the engine with the sterndrive off? This is assuming you supply running water to the raw water.
