    115 6c TOP piston cylinder issue

    I am not sure I follow your comments. Here is my interpretation. Endcaps will slip out once crankcase is split, and endcap bolts are out. If you need to replace endcap bearing, you will need to pull trigger, stator and flywheel. Upper and lower endcap bearings may be different types. Older...

    Check systems gauge

    Gee, it sounds like a test is in order. I do not think you have the "Check Engine" alarm. I think that is on the V6 engines only. But you can ground the tan wire on the cylinder head and see if the overheat alarm sounds. Testing the no oil and low oil are a bit more involved. You can simply...

    115 6c TOP piston cylinder issue

    You can pull the flywheel, however, unless you need to remove the end cap, there is no advantage. Make sure you mark the stator wires. There are some pairs which must go to the same switchbox, for Ign to function properly. Plan on installing all pistons into the bores after repairs, and then...

    Replacing water pump impeller for first time

    Jeff, you could turn the flywheel to align the splines. A 1/2" socket on one of the outer flywheel bolts does the job. I usually use a lifting eye, with the handle of my ball peen hammer thru it as a lever. You can also move the gearcase rotationally before installing the water tube. That...

    Fuel water separator install

    Gee, remove and siphon the fuel out of the kicker tank and pour off the water. Spend $10 on an electric fuel pump and siphon the fuel off the bottom of the main tank and pour off the water. A water separator works by allowing the water to settle to the bottom of the separator canister. If...

    Replacing water pump impeller for first time

    You will want to replace the impeller, ss wearplate and 2 gaskets as a minimum. Check water pump base for melting (looks like scratches). Replace if found. Check SS liner in upper waterpump. If scratched, replace upper water pump. I take the gearcase off and install it in neutral. I find...

    115 6c TOP piston cylinder issue

    End cap bolts usually come out easily. Not sure why yours are stuck. Removing the outer flywheel (8 5/16" bolts), is usually all that is necessary, if the stator is good it can stay on. Connecting rod screws need to replaced with new, after removal. Sometimes you need to grind down wrench...

    1988 TOP 115 powerhead removal..shift linkage?

    Missing rings is not good. Usually, they rip up the cylinders as they are cast iron, vs the soft aluminum of the pistons. You will need to pull the crank out of the block to fix it, so a good inspection will be possible. The end caps often have shims. Preserve those. Inspect top main...

    1989 Cobra on 4.3 liter engine makes a funny noise

    When I had my sterndrive in salt water, every spring there was small pieces of rusty steel in the bilge. Lots of non-critical items would succumb to rust. You might look around for some of that. Also, the cover over the ring gear, next to and down from, the starter can rust and rattle.

    Is the boat engine level? A list can affect the dipstick level.

    Apparent low oil pressure after coming off plane

    Any idea what oil was put into the engine? The oil pressure switch grounds when there is no oil pressure. Look for a "Peppermint Patty"-like device with a single wire on the block.

    Removing water from gas

    Add an oz or 2 of two cycle oil. It will color the gasoline and alcohol, but not the water. It will be easier to see when siphoning the water off.

    1988 TOP 115 powerhead removal..shift linkage?

    Have you removed the transfer cover? That will give vision to the cylinder. A bore scope is also good, however, you are going to need to pull the piston out anyway. The rings will likely be stuck in their grooves, killing the compression. If the cylinder walls are good, still with a...

    best way to carry gas to the dock

    Years ago a friend had a 25 foot cruiser. He put a 30G drum with a spigot on his pickup (with chocks), and filled it at the gas station. He had a long hose from the truck, downhill to the boat.

    1988 TOP 115 powerhead removal..shift linkage?

    It is often #3 that overheats and fails. Make sure the carbs are clean and the water pump impeller are changed every 3 years or sooner, if you hit suck sand into the motor.

    1988 TOP 115 powerhead removal..shift linkage?

    The shift slider is bolted to the powerhead. As such, the linkage from the shift slider to the shift arm needs to be released. The rubber slider can come out of the slide track to accomplish that. You can also remove the bolt holding the shift arm to the slider linkage.

    Shift cable adjustment

    Mercury's throttle cables push the throttle closed. You want to have the cable push the throttle closed, and then add some preload to the throttle cable to help you feel neutral. Make sure the idle stop screw is set properly.

    Bayliner contessa wont plane

    A 28 footer with a SBC is marginal on power, IMO. They ought to come with BBCs. Normally on those kinds of boats, with the correct prop, everyone must go into the cabin until we get on plane. The correct prop is a must. Careful placement of load is a must. Try to load the bow as they are...

    Shift cable adjustment

    Mercury shift sliders move forward for forward. Set the engine to neutral, set the control to neutral and adjust the shift cable barrel nut (engine end), so the cable fits the shift slide position.
