    Waterskiing with Merc power of tower

    Hello, I was just wondering if it is better to leave my engine in neutral or shut off when changing water skiers? (besides the obvious of saving gas, safety,less wear on the starter, etc) My question is more about performance, if the engine has been off for a while it seems to need a minute to...

    Hi there, I am trying to figure out what to do this winter. Rebuild, buy new or do nothing with my outboard. A few years ago my mechanic shows my compression readings are in the mid 90's. All between 93 -98%. On an engine this old should I be concerned? What type of issues might I see with...

    Starter motor manufacturers

    I shopping around for an aftermarket starter motor for my 1980 inline 6 and I see there are many different options/prices out there. Are they all pretty much built the same? EMS Global sells one for $73 and wondering if I would be making a big mistake buying solely based on price.

    Just wondering...is there any issue using the new Evinrude lower unit vent/fill screws on a 1980 Mercury outboard? I don't live near a Mercury parts shop and I can't see how they are any different except for the fact you need a little hex wrench.

    Winterization "cocktail"

    Does anyone utilize this method? I have never seen it recommended in any service manuals for an older merc 2-stroke but some people have said they just run a special mix of fuel, fogging oil and stabilizer for about 10 minutes rather than pulling the plugs and fogging the cylinders.
