    Johnson water pump possible issue

    Sorry, I obviously did not read your post properly. I am not sure what to suggest. You might check the passage under the waterpump base for blockage. Also, my '98 Johnny has a strainer that was nearly clogged, however, it only ran to the telltale/flush port. After 27 years I cleaned it...

    Ron, I have a '93 Merc 135HPV6. Here are two pictures, if it helps.

    Johnson water pump possible issue

    Gee, when was the waterpump last rebuilt? Ditto on the thermostat. Just so you know, when trimming motor, most props will slip before cooling water to the motor is interrupted.

    Mercury 175 HP V-6, 2.5 liter, Serial # 0G042584

    Gee, Crowley shows it as a 1994 Merc 175HPV6, in the serial number look up. However, it shows it as a 1992 135HPV6 when the diagrams come up. A possible bug in the SW? https://www.crowleymarine.com/mariner/oem-parts/outboard/1992/7135412ad Maybe ebay or someone has one for you. I would...

    Spark plugs for a Merc outboard

    I found some BUHW spark plugs at some local (NJ) advance auto stores for $5 ea. Not all stores have them so they look like leftover stock. You could investigate that route. The BUHW-2 are nearly impossible to find for any low price.

    88150a7 Quicksilver Throttle Issue

    That looks like a universal remote control. You might make sure as Alldodge says, that the cables are correctly attached. Perhaps the OEM has a data sheet on it.

    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.

    What year is my mariner

    You might post the serial number and move this to the Mercury OB forum.

    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...
