    My new ‘66 jupiter gem

    I would be in Heaven, going through those Bins along the Starboard side of the boat. I can see a 1965 90hp Evinrude, a 58 or 59 50hp, and at least a couple of 40hp Johnson, all resting there

    any tire preference for vans at the boat ramp?

    Unless the Ramp is very greasy, I doubt you would have any problem, even with plain old worn out All Season tires.

    Mercury XR2 150 stuggling to get on plane.

    You said in your Original Post "once its on plane it gets going like it used too at WOT" Then later you say your top Rpm is 4500. So has 4500 Rpm always been the fastest the engine has ran?

    1984 75hp L4 with unique problem? I'm baffled!

    You won't as the Water Jackets are Empty, and there is no Exhaust Reverberation to push water into the Cylinder

    1984 75hp L4 with unique problem? I'm baffled!

    The Cylinders that are not firing, what do the plugs look like, Wet or Dry? Inspect the Insulators for Cracks With the Engine running, on Muffs as it will not too bad with only 2 cylinders firing, check that air is entering the Carb, and also check for air-fuel being pushed back, out of the...

    1984 75hp L4 with unique problem? I'm baffled!

    Can the Spark jump a 3/8" Gap? If it can't then it is weak. As for the Timing Light, that doesn't prove the Plug is Firing, all it proves is that the Current is getting to Ground, perhaps through the Plugs, perhaps not.

    1984 75hp L4 with unique problem? I'm baffled!

    In 99+% of the time 1 1/2 turns is too Rich. Are the Floats set correctly? I like to spray a bit of Premix into the carb to see how the engine responds to extra fuel, others will say to choke it momentarily. Your timing light will reveal if Voltage is getting to the Plug, but that is no...

    1984 75hp L4 with unique problem? I'm baffled!

    Having spark doesn't mean the Engine is Firing. If a carb is Plugged, 2 of the Cylinders will not be contributing to the Effort, and in fact are at Risk of getting Pooched from lack of Oil. Too bad you chased off Racer, he is one of the Best on the Board

    Oil change interval, synthetic or no, curious what we all do

    For the last 3 yrs I have been using Pennzoil Ultra Platinum in 3 of my cars, 1 with DI(200,000k), the other two with Sequential FI(300,000K and 20,000K). In the two high Milers, the oil gets very dirty quickly. All the cars seem to have better Throttle Response, and Pick Up since using the...

    Boat listing to left

    There is an Engine Trim Tab, and there Transom Trim Tabs. I rarely(never) think of the one on the Motor. Two of my motors didn't have them, or I had taken it off.

    Prop size

    "Flex" That bit of Misinformation has sold Hundreds of Thousands, if not Millions of SS Props. Grab an Alunimium Prop Blade and try flexing it, The put you hand in Water and move it around. Which one Yields to your hand? Which one is stiffer than your hand? If there is any "flexing" of Prop...

    87 Johnson 30

    That Motor does have a Shallow Water Mechanism, with a bit of thought, and some MacGyvering, a way to move the Tilt/Trim Lock Lever from the Helm could be devised

    Excessive smoking

    What you consider Excessive Smoke might be perfectly Normal. Myself, I like and want that Smoke as it keeps the Skeeters away, and I love the Smell of Burnt 2 Stroke Oil. It is one of the Finest Scents ever created.

    Prop size

    You probably need to drop to an 18, maybe even a 17. Why do you want a 4 blade? What is the WOT Range for your Engine?
