    Lake Association

    In theory anyone be on the Boards, Elected or Appointed. However, in a lot of HOA, it is run by a Clique and Corruption sets in Firmly.

    Two different motors same issue

    Will happen any place where the Humidity is High. I have seen Frost on the outside of Carburetor Throats from that same cooling effect, and have experienced icing in a few of my old cars on cold(between 0c and 6c) rainy days. Run like crap at idle until there is enough heat seeping up through...

    2021 Mercury 115 Pro XS cavitating

    I can tell that's a Mercury Prop. What Model is it, Laser, Mirage, Tempest, or other?(I'm feeling lazy and don't want to look it up) It looks like you boat places the Transom a few inches back from where the Bottom ends ahead of the engine(setback), that allows for a slightly higher engine...

    1959 Evinrude Fat Boy 50hp

    I have searching the Various sites with Documents on old Motors but haven't come up with anything. I would think one of the M terminals on the Ignition Switch, would be where a tach would be hooked up, but I am not going to say to do that just yet. In my 1977 OMC Accessory Book, it shows two...

    Engine backfires around 2500 rpm

    Could also be a crossfire from Spark Plug Wires or Distributor Cap. Acceleration increases the Voltage required to fire the Plug and Electricity doesn't where it goes, as long as it can complete the Circuit.

    1973 johnson 25hp 25R73A

    I really don't like the idea of using a Flex Hone on 2 Strokes, as the balls can mess with the Ports. Rigid Hones can also reveal Wear, by not contacting the Worn Areas. As for the Impeller, I suspect the previous Installer was wiggling the Driveshaft back and forth, instead of turning it...

    2021 Mercury 115 Pro XS cavitating

    On my last Outboard, the Anti-Ventilation plate was a good 2 inches above the Bottom of the hull, and the prop had a good bite on the water

    Part interchange

    Not many parts will change as Mercury made major changes in 1964, in their effort to Silence the Beasts. Though things like Carbs and Ignition are likely to be transferable.

    Does EFI solve the hard start/cranking issue?

    Does your FI car start instantly? I do enjoy watching people, used to FI, try and start a non-TKS carbed Boat. They will grind on the Starter forever, when a Slight Movement of the Throttle will set the Choke, and squirt a bit of gas into the Intake as a Prime. My Carbed I/O gets the choke set...

    Are all 9.9 carbs the same from 93 to 95 to 98

    Maybe, but did you actually do any research?

    1990 5.7. 260 Overcooling at idle.

    Wise of Merc to push Closed Cooling on the Engines used in Salt Water, but a lot of Fresh Water is still loaded with Salts(not just NaCl) that will come out of Suspension, Brackish takes it to another Level. Unfortunately a lot of Builders will not choose the Closed Cooling System because of the...

    2005 175 Evinrudes

    FICHT isn't an Operator Friendly design. Don't see many of them around anymore. Maybe they are being recycled as Anchors. I had one of them, and even though the Powerhead was replaced by OMC as a Precaution, I got rid of it with 40 hrs on it, and it already had, as the Mechanic said "Neat...

    1990 5.7. 260 Overcooling at idle.

    Perhaps Mercury is putting a Coating on the Water Jackets and Passages, they certainly do in the Intake Manifolds.

    1990 5.7. 260 Overcooling at idle.

    While there isn't as much salt in fresh water, there is still plenty of it and other minerals to come out of Suspension at that temp.

    1990 5.7. 260 Overcooling at idle.

    A 160 is too hot for a Raw Water Cooling System. Usable in a Closed System, but a 180 would be used there
