    New-to-me Horizon instrument help

    A friend just upgraded his instruments on his 37-footer and he kindly donated his Horizon MD 100 Mutli & WS 100 Wind instruments so I can use on my much smaller Mirage sailboat. Manuals aren't online, but I know how to use them. Here's my questions about the multi (speed & depth) unit: 1) Comes...

    Help! Weird water leak on 7.5 hp

    1976, 7.5hp Mercury Engine, starts great, runs fine and smooth, but there's water coming from around the top spark plug (see attached picture for location)! If I pull the plug wire, motor runs rougher so it seems the cylinder is firing. Is there a water jacket around the cylinder that could be...

    7.5 Hp Seloc vs Clymer manual?

    I have a Clymer manual for my 7.5 hp Mercury outboard, but it totally skips any info on the reverse lock-out and the whole clamp / mount area in terms of how it works and any tear-down instructions. Needless to say, that's the area I need to work on... Before I shell out money for a Seloc...

    Loosening a seized part?

    A bushing, part of the steering, of my '79 merc 7.5hp is practically seized. See the pic attached (part colored red for clarity). It moves if I twist it with vice grips but it's too hard to twist to work well in use. The teeth are good so I'm hoping I don't have to replace the part. I can't...

    Stuck in Neutral

    I have a '79 7.5hp and when I try to change gears it's stuck in neutral. There's a little "play" in the lever on the side, but it won't go into first or second. Am I missing something...feels like a mechanical problem. Any suggestions?

    Sealant needed on Bottom unit?

    I've replaced the impeller on my '79 7.5 outboard and am wondering if I need to apply a sealant when I put the lower unit back on the engine? There was no gasket when I disassembled it. I have a Clymers manual but it doesn't say? Any help appreciated.

    Not the usual Shift issue

    I have an '84 7.5hp Mercury outboard and the shift lever won't allow me to move out of Neutral. There is some play, but it won't go into either Forward or Reverse. I've dropped the lower unit (and it's still off) to replace the impeller and the lower unit gears work fine. It's like there's a...
