    '84 Mercury Black Max - semi-stripped spark plug holes. Now what?

    SN: 6532700 I just got through a complete rebuild. I've got 2 'loose' spark plugs. They're snug but I can't crank down on #1 & #6. I don't know for sure if they're a problem or not. I fear they'll cause the cylinders to lose compression. Do I need to worry about them? I was looking at some...

    '84 Mercury Black Max - I can't find TDC

    SN: 6532700 I'm through a complete rebuild, now I've got to get the timing right again. I cannot find TDC. I tried using a chop stick and slowly spun the flywheel until the chop stick stopped. I do notice a lull before it starts to go back down. I tried this 4 times and by the pointer arrow, I...

    '84 Mercury Black Max - I can't get the lower back on. Help!

    Serial #: Serial #: 6532700 Well, Wired247 was right. It would have been easier to put the lower on first. My powerhead is bolted to the mid section which is mounted to the back of the boat. I've got a lower that I cannot get back on. I was able to work it all the way to where the water pump...

    Serial #: 6532700 I've got the powerhead completely rebuilt. I've rebuilt the water pump and the lower is in tact. The mid section is on the boat. The powerhead is hanging up in the garage and the lower is on the floor. I can't find any documentation or pictures or parts lists for the...

    How do I seal the cap to the hull?

    I've got a 17.5' bass boat that I had to replace the transom on. The cap is on the boat but I've still got to screw or rivet the backend of it to the hull. That's no problem. What can I use to fill/seal the gaps between the cap and the hull. I've looked at epoxy resin & paste but it'd take an...

    When I bolt the transom mount back onto the transom what keeps the water out of the boat? Looking at parts lists I don't see any rubber grommets or anything but steel bolts, washers & nuts.

    What material do I need to fill a gap or hole in my hull?

    Re: What material do I need to fill a gap or hole in my hull? I epoxied 3/4" marine plywood to the existing 1/4" fiberglass & stringers with some chopped strand mat between them. I used a pretty good bit of epoxy & got it pressed in there pretty good. I couldn't tear it back off. I did the same...

    What material do I need to fill a gap or hole in my hull?

    Re: What material do I need to fill a gap or hole in my hull? WOW! That's an excellent explanation George. Thanks. I need to end up with an exterior finish. So I have to use laminating resin? The 'corner' in the pic is the port back corner. I'm showing a shot from the side and another from...

    What material do I need to fill a gap or hole in my hull?

    I've got a 17.5' bass boat that I had to replace the transom on. I've got the new wood epoxied in and the back/bottom epoxied back on as well but I need to fill about a 1/4" gap between the existing boat and the piece on the back/bottom that I cut off and have now epoxied back on. For the bulk...

    Where can I get spark plug wires for my new rebuilt motor at a reasonable price? I'm seeing that the Mercury wires are about $100.00 a set. What about Sierra or Mallory or . . . How do I determine what wires can be used on this motor?

    Where do dead boats go?

    I tried to find a boat scrap/junk yard here in Central Florida but couldn't find any. I read something about scrap boats always being around marinas. I'm looking at Google Maps and the marinas around here don't have scrap boats anywhere near them. Where do the old, dead, scrap boats (and...

    '84 Merc 150 - V6 2.0 - Rebuild - Compatible heads?

    Serial #6532700 I *think* I ruined my heads. I think I warped them by heating then cooling to remove snapped off bolts. I'm still not really sure. They're also just a bit scored up. So I'm seeing heads on ebay that 'look' liked they'd fit but i don't know if they're really compatible. Would...

    '84 Merc 150 - V6 2.0 - Rebuild - Piston replacement

    Serial #: 6532700 I'm to a point where I'm putting new pistons, pins & needle bearings on the existing connecting rods. I notice discoloration (dark blue/purple) from heat on one of the rods. That's not a problem is it? I've seen vids where they applied heat to the rod before installing the...

    '84 Merc 150 - V6 2.0 - Rebuild Serial #: 6532700 I'm trying to replace the bearings on the crank. I can't get the upper bearing out. I've got a steel pipe that *just* fits inside the seat where the bearing is. I've hit it multiple times with a sledge hammer (not *too* hard). It absolutely...

    '84 Merc 150 - V6 2.0 - Rebuild - Connecting Rods Prep?

    I'm working on a rebuild on my Merc and I need to prep the connecting rods for new needle bearings.

    '84 Merc 150 - V6 2.0 - Rebuild - Torque Wrench?

    I'm rebuilding my Mercury outboard and I need a torque wrench. Harbor Freight has one for $21.99 before discounts/coupons. I've seen torque wrenches like Snap On for $200.00+. What's the difference between an expensive one and a cheap one? This is *one* rebuild job total. I can't figure out...

    I'm cleaning the surfaces on my heads now and noticed some pitting on 2 of the heads, mostly the #5 though. Do I need to worry about this? Is there anything I can do with it or is it shot?
