    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...

    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...
