    Anti Siphon Valve on Fuel Tank Pickup?

    Well that explains why you call yourself dingbat. It is a good thing your fuel lines have lasted 15 years, without leaking fuel into the bilge.

    What is this leaking from my lower unit?

    Smell the stuff. If it stinks like eggs, it is gear oil and not normal. If it smells like oil or gasoline, it is 2 cycle oil and normal.

    Anti Siphon Valve on Fuel Tank Pickup?

    The primer bulb and the fuel line connector DO NOT serve as an anti siphon valve. The A-S valve shuts off the fuel, if the fuel line breaks at a place lower then the fuel level in the tank. if it does that, fuel would siphon into the boat bilge. If your fuel line never dips below the fuel...

    outboard motor mounting height?

    Have someone drive the boat on plane and lean over the transom and see where the antiventilation plate is riding. If the plate is higher, the effect of the trim is lesser, but speed may be higher. "driveability" may also be decreased. Lower mounting may give more effect to the trim, but lower...

    1971 Ted Williams game fisher

    Those motors were made by different manufacturers on different years. A lot of them were air cooled Tecumseh engines. They used a coil under the flywheel, with points and a condenser. Vary similar to a lawnmower of that timeframe. it would best be known as a magneto. I would take it to a...

    Optimax 200 overheating specific conditions

    Still strange behavior. The only suggestion is a possible workaround. Those Merc impellers can get some damage to their bases. This causes less volume to be pumped on idle, and they can overheat. Higher speed pumping is fine. If you are sure the impeller is good, this isn't the issue...

    1996 mercury

    What motor? What part do you want to backflush? There is no standard way to do it, so specifics are needed.

    Oil on choke?

    Old 2 cycle engine? If so, oil kinds gets everywhere. 4 cycle engine? probably still not an issue.

    Gear Oil Questions

    I use full synthetic on my '98 Johnny 150V6. It pushes a heavy boat, for hours on end. I also use this boat in cold temps. I use dino stuff in my '93 Merc 135V6. It pushes my speedboat which is light, and used in warm weather only. Does it really make any difference? Not that I have seen...

    Gear Oil Questions

    Any Marine gear oil for mechanical shift motors (that is what you have?) will work fine. Wallyworld plus many automobile parts places have them for less than $10/qt. Gearcase gaskets are available at marine stores, sometimes at wallyworld and on amazon. Keep a supply of them on hand. Mercury...

    Greetings help with controls

    Is that a 1975 2 cylinder motor? If the motor is 1996 or older, generally any Mercury or universal control will fit. Your current control looks to be a universal panel mount one.

    Ventelation cures

    That behavior is unusual. It should not bog without using trim, and it shouldn't ventilate easily, with the A-V plate at or under the surface. Without anything else to blame, I will blame the prop. Almost all props are cupped these days (have been for 30 years), so that should not be the...

    Optimax 200 overheating specific conditions

    You didn't mention any repairs of the poppit valve. That probably merits an inspection at least. If the poppit valve was sticky, it can cause everything from mild overheat to major overheat.

    1968 ish Johnson please help!!

    Gee, isn't the first thing to check is for spark, followed by compression? If spark is weak or absent, the ign system needs some attention. I believe those motors had twin magnetos with coils, points and condensers. So inspect the coils for cracks. Replace any that are cracked. Then clean...

    Intermittent Starter

    Broken wires/windings in starter, dirty connections in ign keyswitch, wiring harness, solenoid, broken brushes in starter, bad ground somewhere. If it were me, I would inspect all the wiring, clean all the connections and see if it helps. Next is to disassemble the starter, clean it up...

    what does this wire do ?

    A standard Mercury wiring harness would normally have a wire for the tachometer. This wire would run to the control and therefore be available to connect to a tach on the dashboard. I am therefore not sure why someone would need to install that orange wire. That motor looks like an 80's or...

    Ventelation cures

    Have someone drive the boat at cruise, with motor down. Take a look over the transom and observe anti-ventilation plate. It should be riding on the surface of the water. Are there any transducers, speedo pickups or anything else near the prop on the hull?

    Fuel tank size on 92 Sylvan 16' Sea Troller

    Sure, throw a portable tank of fuel in the boat and run her until dry. Make sure you can switch the fuel line to the portable tank.

    Fuel tank size on 92 Sylvan 16' Sea Troller

    Sometimes OEMs like SeaRay have spec sheets on their websites for older models. Fuel capacity is often contained in those specs. You can also try KBB. They have specs too.
