SOURCE: 1974 johnson outboard motor 25hp stalls when hiting high end

Not familiar with that specific motor but had similar vintage smaller HP Johnsons. From my experience it sounds like it could be that the high speed carb adjustment is too lean. What I would try is running the backing off the high speed screw 1/4 turn to 3/4 turn, then test. If works better, screw back in in 1/8 turn increments until the problem recurs, then back out 1/4 turn and leave it there.

SOURCE: i have a johnson outboard motor that drips oil

Yes the prop shaft seal needs to be replaced.Do this sooner than later as water will get into the lower g/box.Sometimes they wear out or fishing line is a bad culprit.Its not a big job but it really needs to be done.The oil will also need replacing.Hope this helps

Evinrude outboards


Johnson and Evinrude carbureted 2-stroke outboards since 1964 require a 50:1 fuel to oil mixture (2%) on engines without an automatic oiling system - 6 gallons of gas to 1 pint of outboard oil.

What is the gas/oil mix for an 80 hp johnson outboard motor


Even thought there are many expert tech's with sometimes more years of experience on this site than some you may find working in a repair shop, and of course many that simply give you their guess as the correct answer. I would recommend calling a Johnson Outboard Dealer or an outboard repair shop.

What is the gas mixture for a 9R-70C?


What a neat little fisher motor. All needle bearing motor so you can run it on 50/1 --would use synthetic for the best operation. Take care of that starter spool- slowly engage the plastic gear to the flywheel before you pull the starter for the start.
