    Water pressure gauge install

    I found a plug on the port head of my 1998 Johnny 150HP carb model, near the top. Easy as pie. Your FICHT will have different heads, but look there anyway.

    Lower unit stripped drain plug

    At one time there was a fitting just for this purpose. The hole was drilled and tapped, and a repair plug was permanently installed. The repair plug has a standard gearcase plug in it. Not sure what the name was. Likely a Mercury product.

    How do these spark plugs look to you?

    They look fine. Those plugs last a real long time. I usually replace them (saltwater) when the hex heads rust, and I use anti corrosion spray on them.

    Leaf springs replacement

    You also need some sort of bracket to hold 'em to the frame, plus the 5 hole plate and new ubolts to hold 'em to the axle, The bracket needs to have the eyes in the right place. It looks to be held on by the fender bolts. I do not think that is the right thing, unless the bracket is angle...

    Thoughts on Sierra carb rebuild kits

    Sierra brand works fine. I have used them many time w/o issue. I have found in one (one) occasion on one parts site, that my Johnny 60*V6 engine had the wrong kits listed, along with the correct kits, for that application. The wrong kits had one wrong gasket. It therefore pays to doublecheck...

    Mercury 80hp pop/backfire out exhaust

    I did not hear a backfire. Maybe it is lean sneeze. However, It makes sense to test the idle pickup and max spark advance and assure they are correct.

    Overheating at idle, cool as a cucumber at speed

    Mercury impellers can get a bit of damage on their bottoms. This will cause them to overheat at idle and still run cool at speed. You might check it for that. If so, replace impeller, wearplate and 2 gaskets.

    1974 Mercury Remote Needed

    You can get a new control with a wiring harness and new ign keyswitch on the web for less than $150. You would then need to adapt the wiring. Alternatively you could get a old remote off fleabay or someplace and stick your ign keyswitch and control cables into it. Those MerControls are real...

    Mercury 150 not performing well under load and drinking gas.

    The fuel pump is connected to the crankcase. As the pistons move up and down, pressure and vacuum from the crankcase is directed to the fuel pump diaghram, which causes it to move in/out. On the other side of the diaghram is the fuel, and some one way valves. As the diaghram moves, fuel is...

    1996 115 Johnson Ocean Runner V4 Will Not Idle J115SLEDR

    You did swap your main jets to the new bowls? After you clean the throttle bodies idle passages. You can remove the side cover to do so. Set the idle mixture screws to 5-3/4 turns open.

    1974 Mercury Remote Needed

    I would expect any Merc remote control would work, mechanically. I ran my '77 MerControl on my '93 Merc w/o issue, after I grafted the electrical. Your '74 likely has the quick disconnect wiring on the exterior of the motor. If the boat harness is good, it could be grafted to a newer control...

    Mercury 150 not performing well under load and drinking gas.

    Check the fuel pump diaphragm. If they leak, a large amount of fuel just leaks into the water, and can foul the spark plugs. After you check compression and spark plug color to make sure she runs on all 6, you may need to richen the carb idle mixture screws (if you have such) so she runs a bit...

    1996 115 Johnson Ocean Runner V4 Will Not Idle J115SLEDR

    The carb has a plate on it's side. That covers the calibration pocket. Carbs also have intermediate air bleed orafice. You probably already cleaned those, right? Also check the carb bowls for warp. Just put a strait edge on the mating surface. They often warp. The spaghetti seals between...

    1996 115 Johnson Ocean Runner V4 Will Not Idle J115SLEDR

    You realize that the idle passages are in the throttle bodies, right? The side covers can come off to clean the idle passages. Also check the calibration pocket.
