    Johnson CD-12

    Quite briefly, water enters through the screen on the forward edge of the underwater exhaust snout. From there, it travels along behind the rectangular plate on the side of the gearcase, to the area below the stainless steel plate below the impeller, through the hole in the plate, acted upon by...

    propeller seal removal

    99% chance you are looking at the oil that you put in the gas, which has gone through the engine and done it's job, then mixed with expelled cooling water and gone out with the thru-hub exhaust. Absolutely normal, and does NOT indicate a seal leak. Stop worrying and don't be trying to fix...

    Possible kill switch problem

    He is saying that on many motors, the pee stream comes out before the water has entered the cylinder block. And I agree.

    1958 Johnson 5.5hp Not Having Power

    Classic story heard many times. Most likely running on only one cylinder. But what racer suggested is valid too.

    1959 35hp RDS-21 Factory options

    If you are interested in "correctness", This was my 1958 some 60 years ago. Key switch and choke were mounted in a dash plate that also housed an ammeter, if generator equipped. "Round Knobs" control was used.

    1964 Speeditwin 28hp / WOT RPM - Prop sizing

    Reviewing this whole matter, I'm going to give you an opinion. My opinion is that your 10-1/2 x12 is ok for your boat. Full throttle operating range for your motor is 4000-5000 RPM. So you are within the ballpark, albeit at the lower end of the ballpark. You also say you are not interested...

    1964 Speeditwin 28hp / WOT RPM - Prop sizing

    Supposedly, these are options for your motor, although they seem to be showing a generic picture. Propco Marine Propellers | Propcopropellers

    1964 Speeditwin 28hp / WOT RPM - Prop sizing

    OK, I looked at the link, and that's what I was thinking when I suggested it might resemble a Boston Whaler. That thing should be just about scarey with that motor. You are way, way, under-propped. It might take as much as a 12". Could your tach be showing 1/2 actual RPM? I dunno, never...

    1964 Speeditwin 28hp / WOT RPM - Prop sizing

    I don't actually remember what a Crosby Sea Sled is. Does it resemble a Boston Whaler?

    1964 Speeditwin 28hp / WOT RPM - Prop sizing

    There is something wrong with this story. That motor should be screaming with such a small prop on such a small boat. That prop should be ok on a houseboat or something.

    Gear Oil Everywhere

    Actually, Capt, I consider that to be pretty darn clean for a 35hp running 15 mins in such a small barrel. You should see what a 1960's motor would do in there, before EPA started cracking down in late '60s. BTW, I run a 1984 35hp on my own personal boat. I consider it the best motor I've...

    Gear Oil Everywhere

    Yep, that's normal also. You won't believe me. I spent 24 years in an outboard dealership's shop, and ran thousands of motors in a big commercial test tank and you won't believe me. Enjoy "fixing" it.

    Gear Oil Everywhere

    Yep, it's that time of year again. Everybody getting out the old outboard and getting ready for boating season. And yep get ready for the seasonal influx of forum posts complaining about gear oil in the barrel or bucket. Likewise, get ready for the influx of replies advising y'all that it...

    Lower unit bearings, water intrusion question

    Bearings are neither stainless nor mild steel. They are precision ground hardened ball and roller bearings. They will be damaged by water just as any other ball or roller bearing. It really depends on how much water, salt or fresh, and how much oil was mixed with the water. As said, only an...

    1954 18 hp Evinrude Fasttwin Frothy Exhaust

    Are they universal? I assumed that I'd have to buy one specific to my engine in order to screw into my drain plug. No, I'm speaking of the squeeze tubes that have a tapered spout that you simply shove into the hole. No threads necessary.

    1954 18 hp Evinrude Fasttwin Frothy Exhaust

    Buy you lower unit oil in a squeeze tube. The float valve in the carburetor doesn't float when lying on it's side. Your years of wrenching on cars don't go back to carburetor days?
