    How to adj. timing on '99 30hp johnson

    I'm curious how one adjusts the timing on a 30hp johnson. Also, is there a way to disable the rev limiter? Lastly, this motor will occasionally run on one cylinder. In every case that it does this, the motor will run normally after putting it in reverse and giving it a little throttle no more...

    A hunting/boating pic or two?

    Anyone have any good hunting pics of some big bucks or ducks? The weather is cold here and we're getting a FEW ducks.. I know most of you guys are out of luck due to the cold but I'm lucky enough to enjoy my old outboards the most at this time of year. I love johnson and evinrude outboards...

    A little photo-essay on laziness

    I had my camera with me today to take a few boating pics while I was working on my duckblinds. Noticed this in the parking lot when I put my boat in. This truck was the only one in the lot besides mine. It was parked in front of the dry hydrant. Not that big of a deal but I then happened to...

    A couple of incorrectly restored OMC's

    Well, I thought someone might like to see a pic of my '53 RD-15 25hp and '56 fastwin 15. I think I put the fastwin decal in the wrong place and also used '51 decals on my '53 25hp. But I like 'em and my motor model says she likes 'em too. But she's a little biased!;) Looking to run them...

    Ignorant about gymnastics and age limits, need help..

    I was just watching the Olympics tonight and noticed that the little Chinese gymnasts (female) looked really young--way younger than 16. I also learned that 16 was the minimum age. Why?? Seems like if they can do it, why not let 'em. Not that the Chinese should be able to flaunt the rules...

    The '53 25hp johnson rides again...

    Or should I say pushes again. The old thing ran pretty nice with not a lot of work. the biggest problem was hand machining a spacer for the transom bracket with a grinder, cutting torch, and gigantic steel washer. I wish I could find a brass one but they wanted 80 bucks at the machine shop to...

    Merc 650 from '73 update

    well guys, I posted a pic of this "little problem" previously and decided I'd try the trusty JB-weld underwater stuff. The kind you knead together. I also bit the bullet and cleaned the carbs. Taking them off wasn't as bad as I thought. The float was stuck on the bottom carb and the float bowls...

    If a person wanted a new truck with good mpg??

    On the way back from buying an old used outboard, my dad and I stopped by to look at some new trucks just to see some prices and mainly gas mileage. I don't like the looks of Nissans so I went to the toyota dealership. They had these humongous tundras for like $50,000 and they got like...

    Scoop on 70's 50hp Evinrudes???

    I'm thinking of buying a used 70's (not sure the year) 50hp evinrude to replace my 3cylinder merc 65hp on my pontoon boat which has a cracked water jacket and water in the bottom cylinder.. I believe the 50hp OMC's are good motors. My dad said the 3 cylinder 65 mercs were weak sisters and the...

    How to change 2-line connector o-rings

    I saw this on another site and quickly "stole" it from a true OMC expert named Garry. I don't think he'd mind. I love to see home-made tools used by OMC service men and thought it might be as useful to others here as it was to me. So here she blows!

    Will a 4.5hp mercury run with 65lbs. of compression?

    A friend got himself a junkpile 4.5hp mercury and brought it to me to see if I could fix it for him. It had a bad coil but I replaced it and it has good spark, I've cleaned the carb and tried squirting fuel into the carb. throat and cylinder. It won't even try to fire. I finally tested...

    '73 merc 650 with hole in water jacket pic and questions

    Guys, The 65 merc I bought on my barge ran great for several tanks of gas but started running on one cylinder. It had done it for a few seconds several times in the past but wouldn't hit at all on the bottom cylinder. I took the plugs out and noticed a little milky stuff on the bottom plug...

    When to replace impeller housing???

    I'm curious about something.... How does one know when to replace a water pump housing??? I know if it is pitted you'd have to. Are there other reasons that aren't obvious? I have a couple of 50's outboards that run too hot although they seem to be pumping lots of water and I've checked...

    Does a '74 650 65hp merc have a charging system?

    Guys, I was wondering if my merc 650 has a charging system? If so, is the generator combined with the starter? Thanks, JBJennings

    Old johnson running hot and can't figure out why

    Guys, I've got a little '57 7.5johnson that's pumping plenty of water but seems to be running hot. After about a 150yd. wide open run water would sizzle on the spark plugs and the rest of the cylinder sides were too hot to touch also, but didn't make the water sizzle. It's hot here of course...

    Foiled fishin' trip story--and some gripin'

    Well, between the 45$ for two 6gallon tanks of gas and the 55$ fishing license, I didn't get to go fishing in my 30year old boat/34yr. old motor that I was pulling behind my 10yr. old pickup that has 242,000 miles on it. My 67 year old dad was also going to be hit for 55$ for his license, too...

    Prop for 24ft. pontoon boat???

    Guys, I have a '74 merc 3cylinder/2carb. 65hp outboard on a 24ft pontoon barge. I can't find any numbers on the outside of the prop but haven't taken it off yet. It will push the pontoon boat with 2 men aboard at 17 mph on the gps. It doesn't sound like the motor is revving up high enough to me...

    Huge nat. gas discovery in Louisiana

    good news in Northwest La.: there has been a huge deposit of natural gas discovered in Northwest Louisiana where I live. It is so vast that companies are leasing up thousands of acres as we speak. My wife's parents are getting offers of 5 or 6000 dollars an acre plus 1/16 royalties for the 2...
