    1988 evinrude 20hp excessive moisture coming from exhaust

    I had a 15 that would overheat even after impeller change and water peeing from indicator. Thermostat was stuck open. Changed thermostat and it then cooled normally (barrel testing with water level above waterpump). I have no idea why it would overheat w/open thermo, but you could change...

    Derating a 5 hp ( ca, 1995 model) to 4 hp

    A different view.. Say your boat currently travels at 5 mph max. A 4 hp would likely push it 4 mph (5 x .8). Block throttle advance so your 5 hp can only achieve 4 mph max (get a free gps phone app for testing). You could use a lead split-shot sinker pinched on throttle cable to block the...

    What 15 carb fits my 9.9?

    ‘74 - ‘87 are all metal carbs and should bolt right up. May need longer air silencer box mounting bolts (2). ‘88-‘92 will bolt right up. ‘93+ have a different choke linkage and will not fit correctly. I have done a few of these conversions (carb only), my 14’ (25hp max rated) went from 18 to...

    When do you replace the fuel filter?

    If you can easily blow through the fuel inlet barb when filter is installed, it will work just fine.

    Johnson 7.5 Kill switch troubleshooting

    I have seen cd box kill circuit fail, and otherwise work normally. You can turn the idle stop lower, and kill by slowing throttle fully.

    Auction purchase 1973 18hp evinrude issues

    LS needle should be 1 to 1.25 turns open from seated. Likely some debris under the larger compression plug on top of carb. If you didn’t remove/clean/replace, do so. If you did clean that chamber/replace plug, something likely came through to plug one port inside.. Did you replace fuel line...

    84 Johnson fuel line length

    My tank has been in front (14’).. many years and several different motors.. currently 15 Johnson ‘85. No issues at all. 5/16” fuel hose. That said, shorter,thicker hose would offer less resistance for fuel flow, but probably not significant with such a short vertical lift.

    Persistent carb leak & in early run 4HP Lightwin (1969 Model 4906B)

    Carb bowl chamber must vent to atmosphere. If vent is clogged, fuel will pour out carb throat when pumping primer bulb.

    1995 5.7 bogs/pops at 4200 rpm. Thunderbolt IV ignition, non-vortec.

    Newer rebuilt long block installed 2017 and has run normally until this spring. Runs flawlessly until 4200 rpm, then seems to cut out partially and a few pops. Advancing throttle to wide open makes symptoms decrease, but still not right and rpm gets to about 4500. My mechanic buddy assumed a...

    Weed shark?

    I've seen these on smaller outboards over the years and was contemplating rigging something similar, as these haven't been produced for years. Can't find much info, besides the fact that it is sharpened, high-grade steel, epoxied to the gearcase so that the inner/leading prop edge is very close...

    1996 25hp Evinrude 3 cylinder recirc hoses?

    E25TKLEDC. Just picked this up on trade w/no spark, (I've never worked on a 3 cylinder, or oil injected). Solved spark issue w/CD box. This one has had the oil injection disabled and is now premix. My question is, there are 6 small hose barb nipples on port side of block where the cylinders...

    '58 5.5 CD-15 overheats after impeller change

    This one had been sitting for 15 yrs. Cracked coils and ignition taken care of. Barrel tested and it ran good, but little water output at low idle, better-not much at high idle (Barrel water just below exhaust port.. plenty deep). Water splashed on head boils. So I figured the impeller was...

    1984 9.9 Evinrude starves for fuel

    This motor now has a 15hp carb and apparently ran fine after carb install. Brought to me needing choke to run.. I assumed a partially clogged main jet. Pulled carb and jet was clear (cleaned w/thin wire anyway and blew out). Rest of carb clean/low speed passages clear, float level when...

    Don't know what forum to put this but..

    That friggin' pop-up ad is EXTREMELY annoying! Hey mods.. I understand that the pop-up is a revenue stream for this wonderful site, but how about disabling it after I close it once or twice? Thing just keeps popping up while trying to navigate. Thanks for your help!
