    Great little motor...as above no reverse...requiring some planning ahead...and a variable fuel flow for slow speed trolling..
    Thanks Inveratta. Great offer of help. This is what Ausfish is all about IMO. Like minded fishos helping each other. My Johnson outboard is Model No. 4BR76M, so I am guessing a 1976 model, serial number is A604280. There is definitely no gear change lever, but I can see where one could have been attached on another model (see photo), I removed the cowling today to check essentials. Flywheel is turning okay and prop is fixed. The carby is draining some gunk, so I am guessing a full strip and claen is in order, I am waiting to hear from Marine Direct Australia if a carby repair kit can be sourced within Australia, otherwise I may have to go to USA (not keen). My thoughts are to do the following jobs, put some new fuel in the tank and see how she goes.

    1.Clean out fuel tank
    2. Strip and clean carby, replace parts as required. Is the Repco carby cleaner spray ok for this job?
    3. Change spark plugs, new Champion J6C motorcycle plugs
    4. Change gear oil.

    I am no mechanic and have probably missed something esential here so I am happy to accept advice, if further work is required.

    I live in Brisbane which motivated me to start this lockdown project. Coincidentally, I need to travel to Melbourne as soon as the borders are open again. I would be happy to take your outboard motor off your hands for future spare parts. This project is a labour of love for me as the boat and motor belonged to my Dad and I gave an undertaking to get it back on the water at some stage, I hope you can hang on for a few more days, possibly weeks until I can get to Melbourne. I am driving down in my truck so transport is not an issue.

    Thanks again SS.

    Hi Seastrength, unless my eyes are playing tricks on me but what appears to be running strakes on either side of the keel are moving, in the first pic, the strake appear to be positioned almost half way on the transom bottom edge and in the last pic pic the right one seems to have moved almost to the corner of the transom, or they just a piece of ally channel you are using as a straight edge? I can't tell because of the low res of the pictures, so am I seeing things or are you moving them?

    Hi Ed
    All good, strakes are pop rivetted to the hull. It is punt style design, so both photos show the strake beginning at the bow, not the transom. Creates an optical illusion (I think) when you have a flat bow and transom. Cheers SS

    Had a good day today working on the motor. Striiped and cleaned the carby, fuel tank, checked and cleaned the points, changed the spark plugs, new gear oil and starter rope. That recoil spring bit me in the bum a few times. Boy, is that one tricky beast to get back into position. There is a YouTube video devoted to this problem alone. I could not get a new impeller kit so had to go with the old one for now. Put the motor in the tank, four pulls without choke, six pulls with choke and she fired up after 31 years in the shed! These motors are little rippers. Will make a start on the paint stripping Friday after a day off tomorrow fishing. Cheers SS

    Managed to get more work done on the little tinny today in Queensland lockdown number 3. Since my last post, I have had the outside of the hull blasted with garnet to remove all the old paint. This has given me access to the bare alloy seams and pop rivets which were leaking. After two applications of grey marine sikaflex, she is now waterproof. I am undecided as to whether to repaint the hull at this stage, A new alloy dolly trailer and handle on the front have been added and I can now launch and retrieve easily from the ute tray. Middle seat has been removed to allow the crab pots to sit flat on the floor. Today was spent sanding back all the old plastibond filler over the internal joints and priming for painting. Plywood floor to go in tomorrow all going well with the weather. SS
