    1967 evinrude 80 hp need help.

    Top pic #s 23, 46, 50, 42 Lower pic #s 67 Sometimes the oil appears glittery, sometimes there are small bits of metal, sometimes not. Some analysis/inspection of the Linkage and of the Internals will reveal. I suspect the linkage was bent

    1967 evinrude 80 hp need help.

    That is the prop we used to run on our old 90. It is a Small hub prop, instead of the larger hub props that were the other choices

    1986 Mercury 25XD

    Welcome to iboats First things first. What are the Compression Numbers? Perhaps the Plug Wire is no Good? You can swap the Wires to see if the spark moves to the other Cylinder Is the Coil Cracked? You can swap the Coils to see if the No Spark moves to the other Cylinder. If not then you...

    1967 evinrude 80 hp need help.

    Those Lower Units are not difficult to repair. And it gives you a chance to replace the Pump Impeller. I made the comment about 'Easing it into Gear', cause many People do that, thinking that there is some sort of Friction Plate in there. There isn't, just a couple of Teeth on the Clutch Dog...

    1967 evinrude 80 hp need help.

    I hope neither of you were 'easing it into gear'. I would suspect worn Clutch Dog, and Gears. I noticed that you have a 10 X 9 1/4" Prop on it.

    Need propeller suggestions

    First make sure the Engine is in good shape and is able to make its power, especially since that engine appears to be severely Overpropped. Oh, Great, Tachometer Ears

    Re power - 2 cylinder vs 3 cylinder Johnson 50hp

    The 3 will have slightly more Torque over a wider Rpm Range, because it is easier to Tune the Exhaust on a 3 cylinder than on a 2. It will likely have slightly better Fuel Economy as well, also due to the Exhaust Tuning. Racer points out an Important difference regarding Longevity Having the...

    Rebuilt Carburetor… Still No Idle!

    That brass tube, may have been a part of the Carb Body, that wasn't supposed to be removed. Maybe the previous "rebuilder" somehow pulled it out and didn't get it back in properly Most OMC Carbs, set the float by

    Russian spacecraft crashes into moon

    That one was 1992. I have a lot of pics(6 or 7 rolls of 36, though nothing compared to what are taken with todays ML) from that airshow, and quite a few of various Russian Fighters. There was one Mig(I think) there that did some Incredible Maneuvers, quite close to the ground too. For Decades...

    Russian spacecraft crashes into moon

    I was in High School when Canada did its Conversion to Metric, and I am quite good at functioning in Both Systems. I know there are 1.6kms in a Mile, 2.2 lbs in a Kilogram. that 0C is 32F, 10C is 50F, 20C is 68, and 30C is just too damn hot Every 10C change is 18F chance 4.54 Liters make a...

    Piranha prop selection help

    I would say the 15" was too small for the Boat, but an 800+ rpm drop is about double the change expected. So something else is involved. Perhaps the 15 was also slipping from air injection. I can't see how high the engine is mounted on the Transom... This what a Cleaver Blade Looks like I never...

    Time for New Prop

    A Canoe is a Displacement Hull, and I suspect that 15 hp is far more than it actually needs. A six hp would likely push it just very slightly slower than the 15. Displacement Hulls take very little power to push, up to a point, at that point quadrupling the hp, will only increase the speed...

    Need propeller suggestions

    If you gained 1000 by dropping 2" in Pitch, your 17" is slipping badly. A 2" change in Pitch is, almost universally, a 400 Rpm change. Perhaps the engine was rigged with a SS in mind, but is mounted too high for an AL. I call BS on the Flexing Nonsense. That bit of Misinformation has sold...

    Need propeller suggestions

    What is the WOT range for that Engine? If it is something like 5500-6000, and you are only getting 4200, you are going to need to drop far more than 2" in Pitch to get even close to that Rpm Range, somewhere along the lines of 6 or 7 inches. Was the Motor and Boat a Package Deal from a Dealer...

    Rebuilt Carburetor… Still No Idle!

    Welcome to iboats Is the Float set correctly? You say you used a Kit? OMC/BRP or some other brand? What parts did you replace?

    Looking at a boat with a 1995 Evinrude 120 V4, anything I should know?

    The first couple of yrs for the V4 Loopers were riddled with Issues, but by 95 the bugs had been ironed out. As mentioned a Compression Check, and Gear Oil, but that could have been changed when the Boat was being prepped for sale. Check the Integrity of the Transom by locking the Engine at full...
