    Any help til trim switch

    The x8 series were OMC low cost engines. At 50ish HP and being a low cost model, expect it to be absent. If it had trim, you would see the ram and pump between the transom brackets.

    Can I switch out Mercury 9.9 kill switch?

    Texas P&W Service, (the water cops) says that you need to have a kill switch connected to a lanyard that is attached to your body when operating your boat in Texas waters......check your state laws.

    1986 115hp inline 6

    The engine is water cooled, not air cooled. I answered the blanket question elsewhere on today's forum www or on another which I frequent together with this one.

    1986 vs 1999

    Case in point, Mercury 2 strokes of the late 90's and early 20's, per the service manual, as an example the manual lists verbiage for 60 thru 125 hp. The 60 hp model is a 75 hp with a Jet LU to give you the example of the available power not counting the efficiency, and probably lack thereof, of...

    Inline 6 Sound Blanket

    The sound blanket was made of loose weave, like scattered hay, stiff but loose, could compress if you squeezed, would spring back when released. It was about 1" thick, completely covered in plastic to prevent intrusion of liquid components of different types. It lined the center removable...

    1996 Mercury 75 hp prop

    I know this is later than your fixing your problem but rev limiters like I have on my 2002 115 2 stroke can give you the wrong answer as you found out. Had you not had the rev limiter your RPMs with your 15P would have had revs over the upper limit of 6k RPM.....I'd bet. Then it would have...

    Speed Plateaus at 5200rpm

    You need to remove the prop to see whether or not the hub has slipped, monitoring YOUR scribe line connecting the splined hub to the outer barrel. Glad you made it back on here.....the saga continues. Good luck.

    Anchor Rope

    I never had a problem splicing 3 strand line including 2" manilla" largest diameter line on the tug where I spent a summer vacation as a deck hand. In using the Fid, a conical, hand held instrument made to open the "lays" of the line for insertion of a lay, in short or long splicing. I was...

    Anchor Rope

    Thats funny. My nautical training called ropes "line", the floor the "deck" and the crapper the "head".

    Boat trailer brakes

    If I were to buy another boat requiring brakes on the axles (4500# is the Texas crossover point) they would be electric discs. Just seem to be the right type for aqua environments.

    Anchor Rope

    I don't like poly as it doesn't resist abrasion....course moot point but do you really want your anchor rope to float.....a floating ski rope is different....no abrasion and you want it to float. I don't like Sisal as it is abrasive to your hands. Nylon stretches but resists water damage and...

    Speed Plateaus at 5200rpm

    Well, obviously I picked it up in my limited boating circles when a teen. I see the misnomer is widespread. Course, people who write articles for the news media don't necessarily know what they are talking about either. Case in point the word "re-iterate". it has to be said and repeated...

    Speed Plateaus at 5200rpm

    Er ah Antiventilation Plate. Cavitation is most prominent on propeller tips and the more dings the worse it is. Antiventilation is the purpose of the plate above the prop.....reduces the propeller's ability to suck surface air into the slipstream and cause ventilation....air where water should...

    '99 Merc 115. Yellow stator wires fried.

    Simply Ohm's law: Power dissipated equals current squared x resistance. if resistance is zero, zero squared is still zero and power dissipated (heat) is also zero. Since power is a second order equation the dissipation rises logarithmetically...{exponentially) as the resistance is increased...

    Prop spin

    I don't in R either, just a few degrees , obviously N spins freely. In F since the gearbox contains an overrun clutch, which is nothing more than a gear ground in a saw toothed configuration such that CW, in the overrun position, turning the prop causes the teeth to slide over the ramp causing...

    Speed Plateaus at 5200rpm

    No doubt, the higher you can get the LU out of the water the lower the drag and higher the speed and RPMs. Just how high depends on a lot of factors and mainly selecting a prop that runs shallow and doesn't blow out. Without that you are relieving yourself into the wind......ugh....grin. I...

    '99 Merc 115. Yellow stator wires fried.

    The service manual states otherwise! Besides, seldom do normal requirements require the full 16 amps for an extended period of time to maintain a charged battery, if amperage ever gets that high with maintenance charging.....I doubt it! Add connector corrosion to trying to charge a discharged...

    Speed Plateaus at 5200rpm

    Lineup looks OK but lowering the engine an inch would help. Just commenting on pictures, not other responses on height. Also, I don't detect any "cupping" in the SS prop.....which are usually cupped.....each prop design determines just how much cupping is right for that design.....lots of cup...

    70hp evinrude pitch size advice

    As I recall after having this boat for several years, I dialed in the tab for my upper RPM operation. Had it not been a PIA at other trim settings I would not have gone to the expense and labor of installing NFB steering....2002 115 2 stroke Merc and Crestliner 1750 Fish Hawk. Oh, while I was...
