    Compression Test without a battery?

    A large and powerful, non-Hammer Drill could be used. However Newton's 3rd Law would likely have the Operator going in Circles around the Engine

    how to break in a rebuilt 60 hp Merc 2 stroke ?

    While the Mixing System on the V6s and later 3 and 4 cylinder Loopers is okay, the 'Autoblend' System brought out for the Older Inline Engines, should be removed from the Fuel Line, thrown as far possible from the Boat, preferably into a Fire Pit.

    Compression Test without a battery?

    NOT a GOOD Idea, as that will lead to an Over Torqued Flywheel Nut, and possible Damage the Crank and Flywheel

    how to break in a rebuilt 60 hp Merc 2 stroke ?

    Mercury considers the first 10 hours as the Break-in Period. With older(pre Oil Mixing System) 24:1 was specified for the Break-in. Engines with Premixing Systems, 50:1 in the tank was specified for that period, just to Insure the Engine had some oil, if the PreMixing System wasn't working...

    Compression Test without a battery?

    The 115, consists of 6 relatively small Pistons, and once all the Sparkplugs are removed, it isn't too hard to turn over. I used to rope start my 84 115, as I was was too cheap to buy a new Battery. On a cold engine, it usually took 2 attempts for it to catch and run.

    The primer bulb should be hard, only with the Engine stopped and the Carbs filled, once the engine is running, the inlet valve in the carb will open and the Line between the Bulb and the Fuel Pump is no longer under pressure, and the bulb will be soft. If there is a restriction in the Fuel line...

    Running 5.7 without choke on quadrajet?

    Gee, that's kind how my engine starts, without having to do any pumping of the Throttle, just move it enough, to set the Choke and Fast Idle Cam. After 20 seconds, reduce idle speed, and you are goods to go. Just stay below 2000 till the Engine Temp comes up.

    84 Evinrude bogging full throttle surge

    Start with a Compression Test As for timing, there is no Spec for Timing at Idle speeds. Only Specs for maximum Advance, and another Spec for when the Carb just starts to open the slightest bit. Have you verified that the Spark is not dropping out on one Cylinder as the Throttle is increased? Is...

    Quit on the Water!

    Feeler Gauge and Screwdriver fit in the Port with lots of room to spare. A Matchbook was close to 0.020" and the Striker Strip could be used for Dressing/Cleaning the Points.

    Quit on the Water!

    I don't recall seeing an Access Hole on our 64 5.5, I do remember it on the 57 35. The 63 40hp didn't have it either. Only time I saw the Points on that engine was when the Flywheel came loose, and lifted off the Crank

    Quit on the Water!

    I recall in the late 50s OMC put an Access Hole in the Flywheels of the 35hps, which helped locating the Points, where they would be fully open, and allowed adjustment without taking the Flywheel off. They later did away wth that and put some Ridges on the Armature Plate where a special Timing...

    Running 5.7 without choke on quadrajet?

    Yes. It might be a bit more difficult to keep running right after start up, but copious amounts of Priming prior to starting, will help. but expect a few stalls
