    Prop Fitment

    In the late 70s Mercury made some changes to the Prop Hubs and different Thrust Washers were required. Fast Forward 40+ Years, and throw in a few more Brands of Props and it can get complicated/confusing very quickly

    How was the engine Winterized? There might be some Gum and Varnish gumming up some of the Carb Passages and Air Bleeds. Happens when Fuel sits a long time without being Stabilized.

    Prop Advice

    The normal way of getting on Plane is to use Full Throttle, then back off the Throttle as the boat nears the desired speed. As for propping, it is desirable to prop in the upper half of the RPM Range, but going for the max at normal load opens up the risk of over revving at light loads if...

    Safety chains are hot?

    Fuses pop when they are asked to carry more current than designed for. If the Safety Cables were indeed completing the circuit, they are large enough to carry more current than the Trailer would ever use. If the Hooks or whatever attaches the Cables to the Hitch, can flop around, they could get...

    1986 90hp Merc pwr of twr lower unit disassembly

    At the front of the Propshaft, there is a Hole, that the shift plunger goes in to move the Clutch Dog. 3(I think) balls go in there to provide an antifriction friction surface for the Plunger when the Propshaft is spinning. This is not the case for your engine but the Propshaft assembly is...

    1986 90hp Merc pwr of twr lower unit disassembly

    I will assume you mean Pinion Gear, not Planetary Gear. Once the Nut holding the Gear to the Driveshaft is removed, there is nothing but some friction of the splines holding the gear on. You say you found some pieces of Bearing in the gears? How do the Teeth on all the Gear look? If the Bearings...

    2005 VP 5.7 Gi-e, Rough Idle No Power to Plane

    Does the Boat have a Water Separator Filter? Perhaps those 50 gallons were not just Gasoline.

    Lack of power

    Check the Firing Order, and verify that the Wires are going to correct Cylinder. Swapping a couple wires may or may not make a difference. However if you already have 2 swapped, 2 more can certainly kill the engine.

    Misfire diagnosis

    Disconnect the Wire at the Spark Plug while engine is running, using insulated Pliers. That will show if that cylinder was firing or not

    What brand of 2 stroke oil do you use for your Johnson Evinrude 2 stroke

    I remember seeing that on the XD100 Label when it first came out. Last time I checked(a couple of years ago), that Caveat was no longer on the Label.

    What brand of 2 stroke oil do you use for your Johnson Evinrude 2 stroke

    When I owned an Outboard, I always used Oils from the Engine Manufacturers(OMC and Mercury). They are Very Good Oils and don't cost much more than a 3rd Party Oil. As for the smoke, it will help keep the Mosquitos at Bay, and I really like the Smell of Burnt TCW-* Some will argue that any Oil...
