    Here, it has rained everyday, some days all day, for the last 6 weeks. I am starting to grow webs between my toes.

    its hot

    It hit 32.5 Yesterday, Bloody Hot. I guess that would 90.5F. I prefer temps around 15C/59F, hot enough for shorts and short sleeves, even then I will have the AC going, to dry the Air

    gear box oil leaking

    Where is the Oil leaking out? Is it actually Gear Oil? Being a 2 stroke, that engine will expel unburnt 2 stroke oil, out the exhaust and often, also thru various drains in the gearcase. That said, you say you just got it back from a Mechanic who replaced the Water pump, and likely the gearcase...

    Lower unit seal

    Don't forget to replace the Gaskets on the Drain and Vent Screws. They have been known to let a few Drops of Water get in.

    Very Good chance indeed, every Drill I have ever used, had plenty of Sparks happening inside it.

    Mariner 150 2 stroke need help please!

    Well, you just learned that running Great on Muffs means Nothing, these engines will sound fine running on 3, even 2 Cylinders when on the Muffs. No Backpressure. Put it in the Lake, it is a different Story. Does it have a Spark the can jump 3/8", on all cylinders? Does the Fuel Pump supply...

    Engine wont shut off with key

    Usually, I would say a Key Switch issue, but not knowing the History of what has been done to that Boat's/Engine's Electrical, it might be several things

    No start after cap change and wire hacks

    Now that the Bilge is full of Gasoline, I recommend that you refrain from doing anything in the boat that requires electricity, until it is removed and purged of all vapour.

    What is this leaking from my lower unit?

    Even Gear Oil can pick up Contaminates that it comes into contact with. Use you Nose to give you an Idea, or better yet, do, or get someone to do, a Vacuum-Pressure Test on the gearcase

    Plugs fouling

    On Holleys, the Primaries have Main Jets, along with addition Fuel being added thru the Power Circuit, when the Power Valve opens under load. Most Secondaries but not all, do away with the Power Valve Circuit, and therefore the Main Jets are larger from the get go. Getting an Auto/Truck Carb...

    1985 50HP 4-cylinder power loss

    There are much better Snake Oils than SeaFoam. Power Tune(Merc) and Engine Cleaner(BRP) are good ones. CRC makes a couple that would be okay as well You could try them before tearing things apart.

    1975 Evinrude 135

    Well, the carbs stay fully closed until very late in the Throttle, almost all of the timing Advance happens before they even move a fraction from fully closed. Is the Ignition Plate, under the Flywheel rotating when the Throttle is advanced?

    1985 50HP 4-cylinder power loss

    Yup. I didn't say it was gonna easy, but you need to see if there is scoring and/or stuck Rings. There is no Cylinder Head that can be removed. I guess you could put a camera into the Spark Plug Holes to look at the walls. Take the plugs out and look at them. they often reveal clues if something...

    Is the Throttle Cable hooked up? If so, does the Linkage move as the Lever is moved?

    1985 50HP 4-cylinder power loss

    They are on the Starboard Side of the engine, a few bolts and they come off. Once off, the Ports will be visible, allowing inspection of the Piston and Rings Take Pictures before disassembly so you know what and where things were attached to them

    Stolen!!!

    Unlikely long enough to reach high enough to be visible all around when anchored. That includes people standing in the boat. This one is barely adequate
