    72 50hp Johnson cylinder seems to be running on one cylinder

    I have a 72 Johnson 50hp that I can't get to idle. In the last three years its had a new power pack, a new timer base, new coils, a fuel pump and 3 carb rebuilds. It runs with no knocking on muffs with the start lever advanced a little. And we've even had a couple summers of running around...

    96 Volvo Penta 5.7L

    I have a boat that I acquired from a friend's estate. It was stored outside and not touched for 7 years. At some point in time it froze enough to pop 5 of the core plugs at the bottom of the block. It's not been run since that happened until yesterday. I've been tinkering and managed to bring...

    Volvo 5.8fl PHUE freeze plugs

    Just inherited a 1996 Monterey 210 with a volvo 5.8fl PHUE penta duoprop setup. This boat was sitting out in the elements for 6 years untouched (shame really, it was in pretty good shape before it's "vacation"...) I have not got a service manual yet, I just got it in the driveway last...

    72 Johnson 50 hp control box switch (f-n-r)

    I have an old johnson with hydro-electric shift. As is the case with most of these old remote controls, mine is missing the switch in the control box that controls F-N-R. I currently have it wired with a 3 way light switch, and it's adequate, not optimal. I've bought 2 or three control boxes...

    72 Johnson 50hp fuel pump issue

    Had a little mishap this past weekend. Plug in the bottom carb float bowl worked its way out. There was even a little fire. Got past all that and made it in under my own power. Didn't see that the plug was out until yesterday when I was on dry ground and looking real close, found it and replaced...

    Success sweet success...

    So I bought a project boat in July with a 72 50hp Johnson, started tinkering and immediately found this site. With ya'll's help I was able to diagnose the ignition system, the electric shift in the lower unit, and the fact that the carbs were in pretty rough shape. Just finished rebuilding the...

    72 Johnson 50 hp electric shift, electric start- won't run at full throttle

    Got her out on the water for the first time (project boat). Just replaced the ignition (all components except the stator), and put a used lower unit on it (original wouldn't shift) Runs OK at idle, and when in neutral I can rev it up just fine. But when I put her in gear and throttle up it's...

    Flywheel touching trigger

    Put a new timer base on, starts at turn of a key :) Pulled flywheel off to double check something, and because I like like to live life on the edge... I noticed that the inner ring appears to be rubbing on the trigger. Should I scrape the epoxy off the timer base and try to adjust trigger...

    72 johnson 50 hp electric shift - no neutral

    I've been bringing this one back to life. With some of ya'lls help I've restored spark and it now runs, but it will not shift into neutral (it's an electric shift). I can see that it's getting power to the wires running down to the gear box. How do I check the solenoids?

    50 hp Johnson no spark redux...

    What does the "THERMO SWITCH ASSY ELECTRIC START MODELS ONLY" do? BMC-0384088 (it's mounted in the exhaust cover and has two purple wires coming out of it.) And if it were bad would it cause a no spark situation?

    1972 Johnson 50 hp

    I've been working through this project boat, and with some of ya'll's help I have isolated my lack of spark to be the timer base or more accurately the ignition trigger. I don't want to buy a new timer base assembly as it would cost more than I gave for the whole boat, and I still can't be 100%...

    72 50 hp Johnson - Electric shift

    Working through my electrical issues, waiting on an after market trigger for the timer base. 99.9% sure that's why I'm not getting spark. Anyway, in looking through everything else I noticed the gear select switch in the controls is shot. Fine, I can use a 3 way switch until I can get another...

    72 Johson 50 HP no spark

    I bought a project boat last weekend (first boat ever) and it has a 72 Johnson Electric start Long shaft. The guy said he blew the starter fuse and left the key on so it didn't have any juice. Motor seemed to have good compression and the ignition coils look brand new, it seemed like it was...
