    Need advice on the sale of a Merc 470 inboard.

    I have a Merc 470 inboard in our old shrimp boat, it was only 3 years old when last used, but has been sitting in the boat since 1992. I've cranked it once a year and someone now wants to buy just the engine not the outdrive. Any idea on how much the engine is worth selling for? The guy has the...

    1999 Johnson 115hp yeann...blahh...yeannnnnn..blahh. Yeah, she's missing.

    The motor starts and idles perfect even though it seems to be getting a little more difficult each time out. I cleaned the carbs, drained the gas for any sign of water, pumped the bulb while running, changed the gear oil, and cleaned all connectors and fuses. Also thought it might have been the...

    Testing System Check Tac, Help

    1) I'm trying to set my boat up correctly, but I believe my tac must be reading wrong. How do I check to make sure it is the Tac? Do I just check the gray wire from the rectifier for a 12volt reading, or do i need to check the resistance? It reads normal most of the time, but jumps a 1000 or...

    Will this Lower-unit fit my 70hp Merc?

    I have been struggling to find a good used lower-unit to put on my 1989 70hp Mercury outboard. A guy has a 1996 75hp Force with a bad cylinder. Will the lower-unit form this motor fit my engine. The style and housing is similiar to those of current model Mercury's. It would be a steal for...

    The Verdict- Why my inline went out after two trips?

    I recently rebuilt my 1978 90hp inline 6. The first time I took it to the water it ran as good as new, but the second trip she completely died out.<br /><br />I tore the powerhead down today and found number 2,3, and 4 piston scuffed. It looked like excess heat on these cylinders caused the...

    1976 Outta style!

    I've been running my 1976 15ft Hydra-sport:Hydra-Flight forever and it would still be going until my motor threw a rod. Anyone know of someone else who owns such a boat, I have never seen one like mine down here in Louisiana and can't find a single picture of one on the web? 30 years old and...

    Just pulled this 1974 engine out of storage to revive it our the past few weeks. I came to crank it yesterday and with a brand new battery the motor only turns over slowly. Is this a problem with the starter possibly. A week ago I had the plugs out and it turned over rapidly like normal. But...

    Loss pressure out the tell tale so I changed the water pump in a 1994 60hp Merc. Had a little more pressure coming out the pee-hole afterwards, so I decided to take it out for a run. I immediately noticed that once under way water was just pouring out from below the powerhead somewhere towards...
