    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

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

    1150 Link & Sync Question

    Being a 77, your engine has a has a WOT range of 4800 - 5300 rpm. A 19 sounds a little long for what you have it on. A lot of boats in my area were running 17" on boats between 15ft and 18 ft. But the only way to know is to run it and see what RPM it pulls at WOT. My first boat was rated for...
