You will have to remove the Parts of the Cowl Support Frame(front and rear) to be able to tilt the Lower Cowl to access the bottom of the Jacket. You...

    Wide Open Throttle RPMs

    Welcome to iboats 4000 is low for WOT, and can be caused by many things. Check to see if the Carbs(Throttle Valves if Fuel Injected) do open fully at Full Throttle. Is it firing on all Cylinders? What are the Compression Numbers for all Cylinders? If the engine Checks out Mechanically, and...

    2004 direct inject Evinrude 115 hp

    If it is a 1994 Direct Injection Engine, but it is not a FICHT, what is it then? FICHT RAM? How high were the High RPMs? Do you have access to a Laptop with the FICHT Software? Can the Spark jump a 3/8" Gap, in fact does it even have Spark?

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

    On yours the Distributor will block the Top Carb but the bottom two will be visible. The throttle shafts run vertically through the carbs and you can observe their rotation. Ignore the Arrows

    Mercury 35 hp outboard timing

    Welcome to iboats. The 3 degrees is not an Idle Timing Spec. It is likely the Spec for the Primary Pickup, which when the Carb is just about to move from from being fully closed. Unlike older cars/truck engines, the timing is what adjusts the Idle Speed, as the Carbs are always fully closed at...

    '83 johnson, fuel not reaching cylinder

    Ease up with the starting Fluid, that stuff is very good at stripping the Oil off the Internals that require it. You say it has spark. Have you tried spraying a bit of Premix into the carbs to see if it fires? The Compression Numbers are low, try another gauge. 1983. I will assume you are...

    Thermostat on 235 Evinrude

    Pressure Relief Valve. Allows more cooling water to flow at higher rpms, and less at lower ones. Thermostat might be a little too small to permit enough flow to meet cooling requirements when engine is warm and running fast
