    1979 40hp lower unit stuck

    The 33.3 cubic in twin was introduced in 1970 as the Mercury 400, by 1972, it was renamed the 402. In 1979 it was renamed the Mercury 40, and in 1984 was changed to a 35hp, likely due to 'Prop Rating'. It was made for a few more years. It did share gearcase housing size with the 44 and the 49.6...

    The Telltale will start peeing as soon as the Block is filling up, nothing to do with the Stats.

    1985 merc 150 black max xr 2, peeing water?

    Water coming out of the Exhaust Vents is Normal, Exhaust coming out of the Telltale once the water is coming out of it, is Not Normal. It should have water coming out of the Telltale within 30 seconds. How Old is the Water Pump Impeller? Better yet. How long have you owned this Motor?

    Have you ever seen this?

    It took only a few seconds to Download the Video.(I have a slow, 30mb copper DSL service. Phone company has been threatening disconnection if I don't switch over to Fiber). Watching the Shift Lever boogieing like it is listening to 'shaking all over', you might consider pulling the Gearcase...

    1979 40hp lower unit stuck

    If you have a Dremel you could try cutting several Slots in the Crank Shaft, then use a Chisel on them, along with a bit more Heat. Just don't cut into the Drive Shaft. You could also try Chilling the Drive Shaft with some CO2, whilst Heating the Crank Shaft. Removing the lower Crank Shaft...

    Just thought I'd share a nice photo.

    It was over 82F, yesterday in North Central Alberta. Only thing that made it bearable was very little Rain so far.

    Is this trailer repairable?

    No, simply the Friction of the Bunks/Rollers against the Hull

    Is this trailer repairable?

    EZLoader does have replacement Parts, mainly for Warranty, but in your Case, just replace the Trailer. Less Headache, and might even be less expensive

    1976 135HP Evinrude No gas going to spark plugs/cylinder

    There should be a Drain Screw(Hex Head with Slot) on each Carb Bowl #35. That can verify that Fuel is getting to the Carb, but doesn't mean the Fuel is getting through the Carb

    No sparking v4

    Any Over-torqueing of a Tapered Fit, will ruin the Flywheel, requiring it be replaced Using an Impact for Tightening is the sign of a Bad Mechanic

    No sparking v4

    I would say that using an Impact Gun in place of a Torque Wrench is not Common Sense, especially on a Tapered Fit. Overtightening will Ruin the Flywheel

    back pressure out of carb 91' 155 hp Mercury.

    If the Carb is spitting Air-Fuel out of it, then the Reeds need to be inspected. A 91, the reeds will be relatively easy to Access, as they are external to the Crankcase. Carbs have be removed first, then the Intake Covers, and then the Reed Assembly. Upon reassembly, a Link and Sync will need...

    Mercury 85HP Thunderbolt Ignition Series??? Whats missing??

    The 72 80hp and the 73 85hp are very different engines. They might have the same Bore and Stroke, but the Induction System is much different. Carb Calibrations would be likely different between the 4 and the 6s The 1978 and later 80hp engines are not the same as the 72 and earlier 80hp This...

    Early in the Season, when the Air is Cooler and Drier, an engine will make more Power than during the Hotter and more Humid Days of Summer. so in July the Rpms may very well be at 4800

    1976 135HP Evinrude No gas going to spark plugs/cylinder

    If it has spark,(a spark at a Plug, in open Air, really means Nothing). Can the Spark jump a 3/8" Gap? Is there fuel in the Carb Bowls? if not, there could be a blockage, or gummed up Inlet Valves in the Carbs I hope you are not trying to start/run it without a supply of Water for the Water...
