    very cool carb and intake manifold causing moisture

    Ever take a Pitcher of Ice Water out of the Fridge on a very Humid Day? Ever notice how water is suddenly on the outside of the Pitcher? Same Thing is happening inside the Carb throat, Enough Ice can build up at the Throttle Plate and effectively seal the Carb closed. That was referred to as Icing.

    How to decarb an outboard?

    Spraying any Water into a 2 Stroke, is right up there with the Stupidest Ideas Ever. Brake Fluid would also be in that list

    Evinrude 60hp - 3 Blade vs 4 Blade Prop Pitch

    What about McCloud Lake between Whitecourt and Swan Hills? You could also head towards Barhead, where Lac la none, is, and Lac St. Anne a few miles further on.

    Intermittent Start - Starflite 75

    You can't use Muffs on that engine, so running it in a Tank is the only way. There was a device marketed that clamped on to the Exhaust Snout, where the Water Intake was located, but they are few and far between these days. Fuel Level in the Carb might be low, making it hard to start. That...

    1978 Mercury 140 low compression

    I also second the idea of a wonky Compression Tester Gauge. I don't think it would run at all with those compression numbers. I guess if someone ran it without oil in the Gas, all cylinders could be pooched, evenly. A couple cans of Merc Power Tune, or BRP Engine Cleaner will help free up any...

    Evinrude 60hp - 3 Blade vs 4 Blade Prop Pitch

    If the 3 blade was a 17, the extra Blade, could account for a lot of the Drop.

    Evinrude 60hp - 3 Blade vs 4 Blade Prop Pitch

    Without knowing what prop was on there prior, it is a crapshoot was to whether this next purchase will be any better. However, a 17" is a pretty fair starting point. You want the Rpms at WOT to be in the upper end of the WOT Rpm range for that engine, which I am going to guess is 4500-5500. Why...
