    1964 big twin electrical gremlin

    Sorry in my haste, I mis-identified the regulator terminals. Untrue statement deleted. Even so, I stand by my suggestion to disconnect all those small wires and establish that the motor runs properly, then sort out the wiring. As it is now, it is not the way it left the factory.

    1964 big twin electrical gremlin

    Sheese, no wonder the fuse blows. + and - are connected together for a dead short. Not only that, as the decal warns against, the battery + is connected to the field terminal. And even if it didn't burn up the regulator, the field connected to the bat (-) would defeat the purpose of the...

    Well that certainly is not right. I haven't got time to look right now---later

    1964 big twin electrical gremlin

    Well the solenoid factory sold another one. They get replaced needlessly 'most every day. Sorry, I couldn't help commenting. Anyhoo, your boat obviously is not wired correctly, and we have no way of knowing what has been done. Does your boat even have a voltage regulator? Only used in...

    Water coming out between power head and lower unit

    Notice core plug #47 in the top of the head. There is another one in the bottom of the head. Very common for the bottom one to rot out. Not necessary to remove the powerhead to replace it. Simply remove the lower rear cowl for access.

    1956 Fleetwin Water intrusion in cylinder?

    First things first: It in NOT normal for water to get into the cylinder under any circumstances. Secondly, water intrusion will slowly but surely destroy the whole powerhead and must be resolved, if it is not too late. The lower carbon seal has a sneaky way of admitting water into the...

    1966 johnson 6hp only firing on one cylinder with spark from both plugs

    Are you talking about 303261 roll pin? The whole seal assembly must be 100% in order to properly do it's job. Big problem is, it will run just fine with no seal at all. However that seal serves a very important function, which is to prevent water from getting into the powerhead/crankcase. It...

    1967 evinrude 80 hp need help.

    Your picture shows plenty of water discharge....BUT how are you supplying water to the motor? Running out of the water on muffs or flusher proves little on those sophisticated cooling systems. Get it in the lake.

    On paper how much faster is a 15 HP compared to a 9.9

    The 9.9 and 15 both came from the factory with the same prop. But the 15 has more horsepower, and runs at higher RPM, so it can swing the prop at higher RPM, which translates to higher speed on the same boat. Having said that, the actual top speed can vary considerably according to boat and...

    Help me adjust carbs on an 85hp Johnson

    To answer your specific questions, no the float levels are not super critical. Eyeball is good enough. Also make sure they drop enough. The only "jets" are the four high speed jets (orifice plugs) in the carburetor bowls. They are not adjustable except by replacement. But they must be...

    1961 johnson 18 hp. Should that be there?

    Should be only one o-ring (in the groove around the drive shaft). Matter of fact, if there was anything pressing down on the drive shaft, it would make the gears whine.

    1964 big twin electrical gremlin

    Well in the first place, the negative post is normally not fused. Secondly, could be a problem with the boat wiring, not the motor. We simply cannot trace the trouble down from a distance.

    1971 evinrude 9.5 bad clutch dog!

    That is the hub. And yes your story suggests it is slipping. Picture shows what is inside there (35hp picture, but same feature)

    Johnson 7,5 hp 2 stroke overheated

    I can't understand Spanish, but I say that motor is OK. Get it out of that can and on a boat and let us know how it goes.

    1972 100hp

    State of the art in 1972. Personally, I don't have a lot of love for the Prestolite Battery CD ignition system. Or the fact that it does not have thru-the-tilt-tube steering. You don't have to go far to find somebody that will bad-mouth the Hydro-Electric Shift, but it actually works well in...

    Johnson 7,5 hp 2 stroke overheated

    I see the problem. The check valve needs to be right at the spark plug port, not way up at the other end of the hose. Let's just say that the hose holds one cubic inch of air. That cubic inch is added to the volume of the combustion chamber. So, if the combustion chamber holds one cubic...

    water in cowling 7.5 seahorse

    Easy fix by removing the rear pan. The Welsh plug is the same as used in carburetors. Your local outboard guy probably has a bunch of them collected in his "goody box".
