    Lower unit oil

    The Robber Barons have been increasing their Gouging a lot lately. I would like to see an Excessive Profit Tax of 150%

    Ford 302 spark plug read

    200 hrs? Did you have it rebuilt, if so, what oil was used during the Break-in and what procedure did you do to break the engine in?

    Ford 302 spark plug read

    How many hours on this Engine? To properly read the Plugs, to see if the Mix at WOT is fine, they would need to be read on the water, right after a WOT run, before any lower speed running can contaminate the Insulator. What plugs are your running and where on the Heat Chart are they located?

    1984 Johnson 35hp tell tale at idle

    To get to the Upper Grommet, the powerhead has to come off. Attached to it will be the Exhaust Tube(9) where the Grommet(115)is located, in the pics, you are looking at the Guide Tube(114) I would attach a water supply to the Water Tube and observe for Leakage from the Guide Tube Area. Water...

    1990 Johnson 90HP 2 Stroke Bogging - Help!

    Your Marvel Mystery Oil is probably what made the Plugs look like they do. You poured the goop in all the Cylinders, only to have it drain out into the crankcase on a couple of them as the Ports were open, which is why they all don't look the same.

    1975 9.9 sea horse

    On most OMC Carbs of that type. With the Fuel Bowl off, invert the Carb, put a New Bowl Gasket on. The top of the Float, which is now on the Bottom, should be Even and Parallel with the Gasket. Idle Mixture Adjustment Screw: LIGHTLY seat the Mixture Screw, then back it out 1 1/2 turns. That is...

    Second mortgage for a carb?

    https://www.holley.com/products/fuel_systems/carburetor_components/rebuild_kits/marine_renew_kit/parts/703-41 The only part I would be questioning, is the Power Valve in the Kit. Holley is all over the Map with the Power Valves in Marine Carbs. You will likely have to buy one the same as the...

    I think the Hydro-Electric Cases are great, and very reliable. Since someone put the Completely Wrong Oil in the Unit, I would be changing it again, a couple more times. Yes the Case is in forward gear when ever the Engine is not Running, or when there is no voltage supplied to either of the...

    Idle speed 40hp 2stroke

    A high Idle Speed puts incredible Stresses on the Drive Train upon shifts into Gear. There is no Slip Clutch to 'Feather' going into gear, it is either in gear or out of gear. A quick concise Shift is the correct way. If you hear any Clack Clack Clack, the shift is too slow. A too high Idle...

    Idle speed 40hp 2stroke

    You will also have adjust the Cable Length after any Idle Stop Adjustment. There needs to be a small amount of Preload on the Throttle Cable. Too much and it becomes difficult to shift, too little and the Idle Speed can be inconsistent

    Boat is slow

    A 13in Pitch sounds a bit big for a 16 ft boat. I would predict a 10 or 11 inch being a better choice. Your engine has a WOT range of 5000-5500 rpm The Scratches on the Face of the Hub, indicate a lot of Slippage between the Prop and the Thrust Washer it is up against. Possibly the Prop Nut...

    Stainless Prop Film

    I really don't like People learning about the Shocking Truth of Electricity, anywhere near Water. I know that any Power to a Dock would have to be on an Isolation Circuit, and should be safe, but there shouldn't be any Stray Currents. I suspect the Marina cut some Corners somewhere and the...

    To see if the Pump is pumping, unhook the Line from the Carb, and spin the Engine So you didn't check or adjust the Float? Edit: How far out did you set the Idle Mixture Screw, when you put the Carb together?
