    1150 Link & Sync Question

    Unless you want to start filling and drilling holes, not much? I guess an Jackplate could be used to raise the Engine and provide some setback as well. But lets see what the Straight Edge reveals. Boats with shallower Vees tend to be a bit Skittish on turns. Those Fins... Myself I would remove...

    1150 Link & Sync Question

    Spray like that could mean the Engine is trimmed in too far, and/or is too low on the transom. I suspect a bit of both. What hole is the trim/tilt rod in, counting the one closest to the transom as #1? I love the Snarl the Inline 6 makes. Did you have a Tach working? If so what RPMs at WOT...

    OMC 3.8l dying at high rpm and weird cranking issue.

    Back Pressure, as all the Exhaust outlets are underwater and full. Vapour Lock is where Fuel Boils in the Fuel Line between the Tank and the Fuel Pump. All liquids boil/flash at lower temps as the Atmospheric Pressure is lowered. Lower pressure in the Fuel Line is what causes the Atmospheric...

    Spreading Manure, again

    Last year there was one guy on here constantly claiming every Prop made before this Pretzel, was inferior. When the Prices were revealed to be near the Orbit of the Moon, he probably thought, it must be even Better than Imagined, with a Price like that... I wonder what his connection to the MFG...

    OMC 3.8l dying at high rpm and weird cranking issue.

    That spring thing is called an Anti-Syphon valve, required by USCG Regulation. It is supposed to prevent the tank from draining it self, but the Lower Pressure provided by the Fuel Pump is supposed to unseat it. There is no removable tube inside the fitting on the tank? Not a great design if you...

    1958 Evinrude Big Twin 35

    By Over Torqueing the Nut, it pushed the Flywheel further down the Taper on the Crankshaft. That would stretch the metal, and from then on the Flywheel would be a little Lower than it is supposed to be. You already say it has hit things below it that it should have cleared. My Book doesn't show...

    Spreading Manure, again

    I see Boat Test is once again shoveling the Manure about an oddball Prop Design. This time 'testing' it on a Configuration that is rarely seen. All their past tests of this Prop, have been great examples of DoubleSpeak, even TripleSpeak, with outright Misrepresentation

    1150 Link & Sync Question

    It was in the 60s when Merc moved the Wire off the Switchbox and on to the Rectifier. However, it never hurts to check, just in case someone in the Past changed it

    Oil Change question

    Tom Kelly, Joe Gavin, and others there, lead a very talented group, especially when one takes into account, no one had ever designed a Machine like that before, and they did it in less than 6 and a half yrs. We now return to the Regular Thread

    Outboard will only start when given 10%-30% throttle. Will not start when given full throttle or half throttle.

    The motor or the woman? Edit: It has to be the motor, a woman is pretty much impossible to Solve.
