    1974 Mercury 115hp I6 2 stroke lower unit put back in help

    There is No 'Easing' it into gear. It is either In or Out of Gear, so the quicker the Shift, the Longer the Clutch Dog and Gears last.

    Merc Outboard - 2 Year Old Engine Failure, 5 Year Extended Warranty Denied

    Too Bad you didn't have the Merc Dealer do the winterizing. Bent Connecting Rods can occur when a Liquid is ingested while the engine is running at speeds higher than Idle. I guess if someone poured a pint of Fogging Oil down a Carb in less than a couple seconds and the engine was running about...

    Best propeller pitch for Frankenstein build.

    Could be a Restriction somewhere in the Fuel System, including Tank Venting, Fuel Pickup in the tank, even a weak fuel pump. Have you tested the Pump for Flow and Pressure? Is there a Filter at the Carb? Is it a 2bbl or a 4bbl?

    Boat shut off and can’t get it started

    It would not make much sense to disable a Starter, if the Skipper is tossed overboard... There are interlocks to prevent power getting to the Starter if the Engine is not in Neutral.

    1965 - 1968 65 HP Mercury outboard motor Magneto distributor issue

    Might very well be a 1968 model as the Magneto was phased out in 68

    Best propeller pitch for Frankenstein build.

    If it exceeds 4600 don't remain there too long, but if it still climbing at 5000, then the prop is really too short.

    The Man Overboard Switch is to kill the Ignition, not disable the Starter

    Sorry, without knowing what the RPMs are at WOT, one cannot be certain if the Prop is correct What was the WOT rpm attained with the old Gearcase? And what was the Pitch on that prop? Once you get the Upper Gear Case replace, here is a Chart from the 1981OMC Accessory Catalog A 17 might be the...

    They were likely painted at the Factory I'm not sure what you are trying to show in the pic. I see a poorly installed Fuel Hose at the Pump Outlet. The Pressure/Suction Line for the Fuel Pump, a couple of yellow Wires with red stripes. And one small hose behind the Fuel Hose Interesting Hex...

    If that is the case, the recommended WOT Range would be 4200 - 4600 rpm. One would choose a Prop that lets the engine run in the upper half of that range. Too much Pitch, and the Motor is overloaded, and can die a horrible twitching death, not enough Pitch leads to over revving, which too, can...

    Best propeller pitch for Frankenstein build.

    What was the Max RPM you were getting at WOT? Also, what is the recommended WOT range of your engine? You do not chose a Prop, for a speed at a certain rpm. A prop is selected by what RPM it allows engine to attain at WOT

    Best propeller pitch for Frankenstein build.

    What prop were you running before you changed the lower unit? and what rpm was it doing? From what I can see, the configuration you currently have is like that of a High Altitude 5 liter motor, which would spin the prop 11% more per Engine RPM, but will load the Engine up more and drop the RPM...
