    Blake I guess I can take a stab at your question. Yes they do have pressure from the motor to move gas to the carb. The pressure two line tanks on OMC motors showed up on the 1949 QD 10 hp Johnson. Evinrude picked them in 1950 on their 14hp fastwin. They stayed around until 1958. The 58 lark and the Javelin had single line systems. I am sure I will be corrected if that is not so! OMC experimented with the single line tank on some gale models somewhere around 55 or56. You can use a pressure tank on a fuel pump motor if you make an adapter. Fisherman 6 has an adapter on some of his videos if you look for them on utube. Mercury had a pressure system also but I am not so sure of the years.

    Anyone know the ID and OD of the packing washers?

    I’ve got to replace mine.

    John

    John, the packing washers are 1/4″id 3/8″od. I make my own from different gasket paper and once in a while from leather pieces. I have been told that Ace hardware has them but I don’t know that for sure. Some people say they use O rings. I have not had any luck with those. You need a washer that will hold the needle in position, sometimes vibration will unscrew the needle and performance will go away quickly. They also need to seal up so they don’t leak fuel or air.

    I pulled the transfer covers off this afternoon. I found a stuck ring on one of the two ring pistons, and a score on the intake side of that piston. After a little carbon scratch’en I found where the gas/oil mix goes from the carburetor, right into the exhaust. Why did those engineers do that? Makes no sense to me. I think I am gonna block that port off completely.

    thanks guys n Happy New Year!

    can you post a picture of the powerhead??

    Sure can! I am the kinda guy that likes to know how things work. I am pretty sure it’s an 18 or 20hp. I was trying to understand the oiling system on this OMC powerhead. The gas/oil mix that gets pumped from the lower main bearing to the top bearing. I originally thought the drilling passages going to the reed block were blocked but they are not there on this engine. The older engines, I am sure you know, use the crankcase pressure to send lube through the motor. I might have to split the cases on this PH, to find out I guess! There is a line that goes from the transfer cover to the carb side of the reed valve that goes nowhere. The usual hose goes from the lower to the upper main bearing is there.

    life is a puzzle! Outboards too!

    Thanks dale

    this a 1958 model QD? If so, it does need one of those spacers, and from the looks of your picture, it is probably in place. Water is supposed to spill out of that hole, that is normal, but there shouldn’t be any exhaust or smoke coming out of there.

    Yes the motor is a 1958. It has a newer gear foot. I bought it without the gear foot and found a good used one. It runs well, the water coming out does not have exhaust coming out with it.

    thanks for the come back!

    Yep.
    You da man!
    And the funny thing is is that I have one!
    Hmmm.
    As Tom and Ray of “Car Talk” like to say, “If you take apart and put a motor back together enough times you’ll have two”
    Gracias,
    G

    Geer and Frank, I was reading your posts concerning the water ports and it reminded me of this QD19 that has water coming out in a strange spot. Is this what you are talking about? See picture.

    The old kicker runs real nice, the water doesn’t seam to be a problem. Does this 10hp need one of those spacer tubes?

    Yes I planned on splitting the crankcase and asses for water rust damage on crankshaft, bearings, reeds etc. My original question was if I could keep the piston rings in the exact order they came off the piston cleaned them up, cleaned piston and piston groove’s and if cylinder cleaned up with a light hone can they be re used satisfactory ? I never really bothered to fix a seized motor before to many good low hour engines in Ohio to be had. I would think if every thing regarding piston rings was assembled the way it was originally with a light hone they would just re seat themselves. Maybe I am wrong. Opinions please. Thank You Bill,

    Bill you motor needs to be evaluated when you get it apart. If you can get the rings off the piston without breaking them you can slide them back into the bore to see what the end gap is. That will tell you how much wear it has. Look for scoring and deep scratch marks on the piston and the bore wall. If you have your engine all apart you sure don’t want to do a half S job on it! Pistons and rings are available, seals and gaskets too! The engine will tell you what it needs, the decision you need to make is how much moo-la you want to put in it!

    billy-j all I can tell you is what I do! I have three assortments of O rings that I bought at harbor freight. Metric and USE a couple other draws of o rings that came in gasket sets that I have saved over the years. Sometimes I still can’t find the size that I need. I have an ACE hardware close to me that usually will find what I want. OE parts are very expensive and when ya put on some shipping charges I can’t stand paying 20 bucks for a 10 cent part! Yes those o rings that go in the fuel connectors might be the exception.
