    '05 Johnson 30 hp 4-stroke Loses Power

    That engine also has a "LIMP mode," which would line up with your symptoms. "The 2005 Johnson 30 hp 4-stroke engine can enter a limp mode, often referred to as S.L.O.W. mode, which is designed to protect the engine from damage due to overheating or other issues. If this occurs, it's important to...

    '05 Johnson 30 hp 4-stroke Loses Power

    Since it is doing it on both cylinders, I would probably go for a new powerpack. If it was a coil, I think you would have a misfire rather than loss of power. did you put an OEM fuel pump on it? I am still stuck on a fuel issue as your symptoms leads to it. Does it act up only under full...

    '05 Johnson 30 hp 4-stroke Loses Power

    Sorry, I overlooked the "loses rpms" bit. Compression, spark, or gasoline could be the source of the problem. I would remove the fuel pump lid, recheck the fuel filter and the plugs, and check the compression. Does it sound like the engine drops a cylinder when it loses power, as if it is just...

    '05 Johnson 30 hp 4-stroke Loses Power

    Sorry, I missed the "loses rpms" part. The issue is likely to be related to either compression, spark, or fuel. I'd pull the fuel pump cover and re-check the fuel filter, recheck the plugs, and verify compression. Does it sound like the engine is dropping a cylinder when it loses power, like it...

    '05 Johnson 30 hp 4-stroke Loses Power

    Does the engine rev up like it should, or is it bogging? If it is revving up normally, it is probably a spun prop hub. Have you checked the compression? Pull the plugs and check the color. If you haven't tampered with the timing, it should be fine. Given all the work you have done, the engine is...

    Any idea what this fits?

    this part is indeed from a marine outboard motor, and more specifically, it appears to be a recoil starter assembly used in vintage Johnson or Evinrude outboards, possibly from the early 1950s era. The part number 590382 matches listings for a recoil assembly used on 5hp Montgomery Ward Sea King...

    Any idea what this fits?

    Cylindrical opening: Likely for a pipe or port—could be where exhaust gases exit or air/fuel enters. • Rectangular opening: Suggests a passage for gases, possibly connecting to a manifold or throttle body. • Bolt holes at corners: Indicates it's designed to be mounted securely to another...

    Hooking up my tack. 1984 50 hp 2 stroke

    Thanks, Droid. I got it figured out. On the power block, the third terminal has the gray wire and the yellow/gray wire. The yellow-gray coming out of the rectifier is both poles unrectified. So I ran a new wire from that terminal up to the tach, and that cured it. There was a white wire going to...

    intake air temp sensor. Is the throttle body dirty? mass airflow sensor? Check the air filter for a mouse nest. Do you have a scan tool?

    1971 Johnson - No anode

    I have had some tell me that the trim tab acts as an anode on my 84 60 hp Evinrude? Not sure if that is correct, but there is nothing else on the lower unit.

    Looky what I found on eBay! Whew!

    I searched across the nation through a few BRP dealers without any success. Set up a saved search on eBay in case one pops up. Yesterday I checked my email at 5 am, and voila! I was on it like a cat on a mouse and got it. A brand new sealed Prestolite relief valve to replace mine that leaks (the...

    Hooking up my tack. 1984 50 hp 2 stroke

    I have owned two 1984 Evinrude 60 hp 2-cylinder engines with a 10-pole stator. On my Faria VDO gauge, I have it set to 10 poles, and it works correctly. I experimented with setting it to 5 poles, but it was significantly inaccurate. The engines have proven to be reliable, exhibiting no problems...

    1984 Corson 15 foot runabout lists to the right with me alone driving.

    Thank you, Makomark. That's my thought as well. Where the driver seat is, the hull looks like a round-bottom canoe and then flares out just behind that. The trim tabs drop down for trolling and then flip up to normal trim tabs that are set at a 25-degree down angle, and then the shocks will push...

    1984 Corson 15 foot runabout lists to the right with me alone driving.

    The boat remains level when empty, but it tilts to port when I sit in the port seat, although it tilts much more to starboard while driving. The floor and foam are both bone dry, and the plywood is solid. I drilled three 1/2" holes along the floor from front to back, and the area around them is...

    84 Evinrude 60hp twin compression and wot rpm range

    Maiden Voyage went excellently! The engine started up after pushing inward on the key switch, which activates an electric primer for a couple seconds, and it idles perfectly at 750-800 RPMs. The transmission is completely silent when the boat shifts into gear. The boat comes up on plane with...

    84 Evinrude 60hp twin compression and wot rpm range

    Hi everyone, I brought the boat home! Compression was great: 135 top, 137 bottom. It starts right up and idles great, but I think it is a bit slow; I will check it with my tiny tach. It shifts instantly without any banging or grinding. I am pleased with it and need to register it today, as well...
