    mercury 800 hot tall tale stream

    Was the engine in gear when you were doing these rev tests? I will be honest, I don't know why you took the Shift/Throttle Control apart. If you didn't get it back together exactly how it was before... I would be looking at the Control, before trying to mess with the Cable length, as I said...

    Date/name of Mercury props

    Perhaps it is an Aluminium version of the Prop, it certainly would be cheaper than a Prop made from X7, wouldn't perform quite as well, but cheaper

    Merc prop selector

    Maybe there are better choices than the Mirage or the Tempest Plus. I think an Enertia would be an Excellent Choice. I have been running one since 2005.

    mercury 800 hot tall tale stream

    1968 1969 70-71 72 You really need the Factory Service Manual to determine where the Teletale gets its water from. I will assume that someone has been in there and added a fitting at the top of the Block, or that was where the Teltale went originally as the fitting at the middle of the...

    mercury 800 hot tall tale stream

    1968 Edit: 1969 would have had Merc 800 on the Side of the Top Cowl towards the front. 1970 and 71 would have had 2 thin Red Stripes above and below the word Mercury on the Cowl Wrap Personally, I think the 68 and 69 Cowl Decals/Graphics are the best Mercury ever had

    mercury 800 hot tall tale stream

    70s Era Merc 800 means 1970, 71, 72, or 1978 Before pulling the carbs off did you verify that they were opening fully? BTW, you don't adjust the Cable Length to get the carbs open fully. You adjust the length once the Idle Speed is set. Now that the Carbs are off, you will need to verify and...

    Easier time putting on the trailer

    They might not work on my trailer as it has a Torsion Axle, with a Drop in the Center, and that Drop will certainly snag the end of a Ramp

    1985 Mercury 115 tower of power

    Most likely cause is a problem with a Exhaust Water Jacket Cover/Gasket(12 & 13) inside the Exhaust Housing in the Port Side of the Engine. 16 & 17 might also be involved A Crack in the Block is another. You will likely see a very clean Piston Crown when you use the Bore Scope

    Mystery Transom Repair... racer is likely referring to the Metal Plate on the outside of the Transom. It does create a Gap between the Transom and the Engines Transom Bracket. There is also some other signs of issues with the Transom. One neat thing about Glass Reinforced Plastic, it can be...
