    Carb linkage adjustment for 1976 Mercury 500 50hp with thunderbolt ignition.

    That Mechanic somehow thought you had a 4 cylinder 2+2 motor, those weird things were more than double the HP of yours

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    Somehow that doesn't shock me. Some Neanderthal just forcing something cause it is too tight.

    Required HP for slalom skiing

    In the Days of 2 Strokes, you could get pulled out easy by a motor of less than 60hp, Today's Torqueless 4 Strokes require 150 - 200hp to pull the same Skier out with the same boat.

    Tow eye hook height for slalom skiing

    Higher Tow Hooks can and do create a Side to Side Rocking, simply because of the Physics involved, Lower Tow Points can reduce that. Of course a lower Tow Point can result in the Tow Line dragging in the Water at speed more often when Slack develops after crossing the Wake and the Skier is...

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    While your fingernail is fairly sharp, whatever is on the Hose, isn't. If there is some goop in there, it might also be in the fitting that you pulled the hose off of

    Carb linkage adjustment for 1976 Mercury 500 50hp with thunderbolt ignition.

    Don't go messing with the Linkage between the Carb and the Spark Timing, unless you do a Link and Sync, and find it out of adjustment. Just make sure both carbs are Closed(I think, both have a small Spring to ensure they are closed) at idle. If they are closed at Idle, and the Linkage between...

    1968-1972

    Check to see of power is going to the Shift Wires under the Cowl when the Control is in Neutral or Reverse. If Power is, then you will be dropping the Gearcase for Inspection. If not, then the problem is in the Wiring to the Control, the switch in the Control. Power must be getting to the...

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    The Enricher gets its fuel from either a Carb Bowl, or from the Fuel Line going to the Carbs. If the Carbs are starved, the enricher will likely be starved too

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    Is this a Permanent Tank, or a Portable Tank? Either way, pull the Fuel Pickup out and check for blockage, of the Strainer on the end of it

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    Those engines had not Overheat Indicators, but a Pressure Gauge that would likely be ignored, was an Option

    I changed my lower end your oil on my Evinrude 18 hp guy at AutoZone said that should work??? making sure

    I know the Stench of either remains on my hands for Days. I finally found that Clorox Bleach will remove the Stench. It will get Hot as it interacts with the Traces of Oil, but at least the Stench will vanish

    Old Evinrude question, Can anyone help?

    I couldn't find that Model # in any of my books, so I went went 55 25hp. As I knew the the Cutout was there on the 55 I know in 57 they had moved the Fuel Filter to the Port Side of the Block

    Should the prop have any play

    If the shaft is not moving in and out, there likely a Washer/Spacer missing. Especially critical is the Thrust Washer, without it, the Prop can end up machining the back of the Gear Housing, and that gets expensive in a hurry as it would have to be replaced

    Easier time putting on the trailer

    To the OP. Don't back in too deep, the Bunks themselves so a great job of centering the boat. Those Guide things are more of a joke than anything else. I have seen many bent because the trailer was way too deep, and the boat was moving around because of Wind and/or Current.
