    Spark plugs for a Merc outboard

    AC also made a line of spark plugs equivalent to L78V. My '76 Merc 1500 came with those from the factory. V440 something was the number on that one. Not sure that helps. What does Merc recommend? You can still get BUHW-2, but they are pricy

    Spark plugs for a Merc outboard

    Gee, Champion spark plugs were used for decades in merc OBs. If memory serves, the BUHW-2 was equivalent to Champ L-78V, which was used in my '73 Merc 850. The 70's and early 80's Il6 motors usually used Champ L-76V.

    What year is my mariner

    You can get the part numbers for the carb kits from a place like crowleymarine or marineengine. You can then source them from most anywhere. ebasicpower is another place for carb kits. It is likely Sierra or GLM make aftermarket carb kits. These are usually just fine to use.

    Product suggestions for deep scratches

    Gee, sand it down around the scratches until bare metal and feathered edges. Use some aluminum self etch primer and then spray with gloss black.

    115hp 2 stroke and quick connects.

    Most 115HP motors like yours will be ok with 5/16 id fuel line. Larger HP motors including Merc V6 motors need 3/8" or larger. I understand what you are trying to accomplish, but sometimes quick connects can starve to engine of fuel. I do not think it is an issue with the IL6, but watch for...

    Check your Prop Folks!!

    Do you think that could have been caused by not tightening the prop nut enough? I would think that if the prop hub had some room to move, it might crack like that.

    Switching from trailering to storing in a saltwater slip... what is a "must do" to protect bravo3?

    The outdrive will need antifouling protection. I would recommend you brush on a coat of Trilux. I have found the spray-on A-F paint to have lousy coverage.

    Is this the idle jet? Or?

    That issue where the motor sneezes after running for a while and then sitting seems to be common on those engines. It is on my '98 Johnny 150HPV6. A work around is to start the sneezing engine and keep her idling high enough in neutral to keep running for a few minutes. After that she should...

    115hp 2 stroke and quick connects.

    Different quick connects use different fuel lines. You need a quick connect for 3/8" fuel line. Make sure the quick connect seals when disconnected, or it will suck air into the fuel system. You might use a fuel selector valve instead. A much better idea as they should seal well.

    1980 Inline 4 80hp power tilt/trim

    The PTT unit from a mid 70's to mid 80's Merc inline 4 or 6 should fit your motor. The PTT unit consists of two trim brackets, two trim cylinders, a pump/reservoir unit that mounts in the boat and w/ hydraulic lines to power the PTT cylinders. While it does work, it is pretty obsolete and...

    1988 115 Inline 6 Fuel Pump

    The Crowleymarine web site shows a figure 8 pump style for that IL6 serial number. It is roughly the shape of the old baseplate. Here is what it looks like. https://www.nlamarine.com/products/mercury-outboard-fuel-pump-assembly-66530a6-13727a1-90hp-115hp-140hp-6cyl-66529?variant=1138636028...

    Outboard wiring conduit

    They make a black plastic tubular mesh as well. A lot of outboard OEMs use it. Dingbats suggestion is a good one. However, I have had that kind of tubing fail from the sun in a year or so. Make sure it is UV resistant.

    cooling system 1999 mercury 150hp 2 stroke

    Zoomie: A 1978 Merc 150HP engine would be the one of the early V6 models. Those have two thermostats each. The last 150HP inline 6 was 1977. These did not have thermostats. JRB: The water outlet of the impeller should go into a copper water tube. When you install a new impeller, you use the...

    1983 merc 115 how to link and sync

    A Mercury Service manual is a real good idea, as the procedure has some details. 1 Synch carbs to open at the same time, using adjustment on plastic levers connecting carb throttle plates. 2 Remove spark plugs 2-6 and put timing light on #1. Remove prop. Set throttle such that carbs are still...

    Hoist engine to remove steering cable? 2001 Starcraft 176

    I think you are very close to getting the steering cable off, w/o moving the engine. Disconnect the cable at the steering wheel end and pull some slack into the splashwell. Now see if you can get the steering rod out of the tilt tube. If not, you can slide the engine to the port side and get...

    1979 80 hp Mercury swap out

    First the control must push the throttle closed in neutral. Second the idle stop screw must be set correctly. Third, it sounds like you need a Mercury Service Manual for your motor. It will have all the specs you need.

    Cold start issues

    Most Merc controls have either a separate push button for choke or push the key in for choke. Your motor has the electric solenoid, but the drawings are unclear if you have a traditional choke plate or enrichener. It doesn't really matter much as both work fine. Remember when cold starting...

    1979 80HP Mercury

    Disconnect the shift cable at the engine. Now when installing the gearcase, move the shift slider a bit to mate the upper and lower shift rods.

    1990 mercruiser 4.3 no spark

    Sure that is compression stroke half the time. The cylinders fire every 720* of rotation in a 4 cycle motor. You might pull the distributor, rotate the engine 360* and reinstall it pointing to #1 spark plug wire.
