    1977 Crestliner Muskie 7**, Outboat Restore Project

    Looks like there is a fair bit of Glass that didn't get saturated with resin I suspect the Keel has rotted as well

    Just thought I'd share a nice photo.

    Another Lava Maker? Think of it as Mother Nature sending a Message to Humans, that they really don't own the Planet. In fact they are more like Parasite to it

    Water is the Lubricant for those Pumps.

    2 Stroke Exhaust...

    Some Boaters cry about a little bit of Smoke, and newer 2 strokes, with Auto Mixing of Oil to gas, are at idle running on 150:1. I would love to see the Criers being near an outboard from the early 50s, those were run at 16:1 and 20:1. Actually, if they are still running today, almost all of...

    Tach non working on Mercury classic 50

    Even if the connectors are good and are connected to the wire well, wires have been known to break inside the Insulation. You should check for continuity. To see if the Charging system is working, just connect a Volt Meter across the Battery, as the RPMs increase so will the Voltage, usually...

    Mercruiser 5.7 won’t make power

    With the intake off, you can easily remove a Lifter or 2 and check for Dishing and other indicators of Camshaft Wear.

    2 Stroke Exhaust...

    At least you knew the 2 stroke was running, and that it provided some protection from Insects. While it tended to Load up after a period of low rpm, a bit of revving in Neutral would clear it out, and provide even better Insect protection

    Mercruiser 5.7 won’t make power

    Hmm, the Vaccum at Idle does look a bit low, but that might be because of the Grind of the Cam, retardation of Cam and/or Spark timing. Did you Degree the Cam when you built the Engine? Also did the Timing Chain Sprockets have more than one Keyway?

    175 2 stroke wont rev past 2k

    Just keep in mind, a Good Spark is one that can jump 3/8". I know that plugs are gapped much closer, but 0.030" in an atmospheric pressure many times Sea Level, is like 1/4" at Sea level. Compressed Air is a better Insulator

    2 Stroke Exhaust...

    Yamaha markets some very good Outboard Oil, as does Mercury. Smoke is the last thing I worry about, besides it helps keep the Mosquitoes at bay

    Mercruiser 5.7 won’t make power

    Just curious, what altitude do you do your boating? Myself the lakes I go to are between 1950 and 2400 feet above Sea Level, and it reflects in the power the engine produces, and also in the Readings on things like Vacuum Gauges

    What is this wire for?

    Interesting that they cut the Wire, as a couple of inches away, are the Knife Connectors, inside the Sleeve next to the finger

    2 Stroke Exhaust...

    There is a lot of Unburnt Gas and Oil that comes out in the Exhaust. Run the Motor in a Barrel for a bit and there will be plenty. However, get a Latex or Nitrile Glove and get some of that brown Liquid on it and smell it. As bad as Gas and semi burnt Oil Smell, they smell like Roses compared to...

    Motor has power, won’t turn over

    The Kill switch isn't part of the Starter Circuit, just the Ignition Circuit. Take out the Spark Plugs and see if it cranks and spits water out Other checks, Battery even though a Battery may show enough Voltage, if it can't produce/provide enough Current, the starter isn't going to crank, so...

    Help diagnosing a problem

    Reading the Original Post. Engine died, and the Starter didn't crank? Replacing Key Switch didn't fix the problem? What about the Neutral Safety Switch in the Control Box? What condition are the Battery Cables and Connectors? If power is applied to the Solenoid Terminal to activate the...

    175 2 stroke wont rev past 2k

    A faulty switchbox will certainly kill the engine's ability to make power but if you are consistently getting spark on all Cylinders, it is hard to condemn a Switchbox Inspect the Wires between the Coils and the Plugs, Inspect the Plugs for any Cracks in the Porcelain. Inspect all the...
