    Johnson RDE 17R repair

    I have a 2 line tank that I rebuilt for my 5.5 (it still leaks anyway) but if I get this motor running, I will add a fuel pump to it.

    Johnson RDE 17R repair

    I got it apart. The top cylinder looks much worse than the bottom. I'll get big bucket of solvent or parts cleaner and dunk everything so I can see better.

    Johnson RDE 17R repair

    I'm hopeful it's just cosmetic and it will clean up. If not, I can make my money back just by selling the electric starter. I have a 5 & 1/2 hp that is pretty much finished, mechanically. I picked up a little jon for it today and I'll start sea trials as soon as I get it registered. If...

    Johnson RDE 17R repair

    Spent a little more time on it today. The lower shifts correctly. Next step is get the magneto off the top and split the case. Not too familiar with the lower seal, but I think that broken plastic ring might be the low quality seal I've read about.

    Johnson RDE 17R repair

    Location is Texas. If it turns out to be a mess, I don't know if I will rebuild or part it out. Haven't decided yet. Don't see very many of these being offered up for sale.

    Johnson RDE 17R repair

    Just remembered this model usually has the bad seal, so I will have to tear it all the way down anyway.

    Johnson RDE 17R repair

    It's locked up solid because it was outdoor decoration, but I'm gonna see what I can do with it. Currently have it taken apart down to the powerhead. I might have to remove it from the lower and split the case to get it free. Being patient and avoiding more damage. It is very similar and still...

    93 Johnson 8hp low compression

    The bad news is I only found 3 of the 4 balls. The good news is I finally found the fragments of the 4th ball, so I didn't lose one.

    93 Johnson 8hp low compression

    Alright, full tank of gas, completely reassembled, engine starts easy with the pull rope. There's a switch on the tiller that does nothing. I assume it's the kill switch, but I'll look into it. Applying the choke at idle is how I'm shutting off for now. Now to study the lower end before I...

    93 Johnson 8hp low compression

    I cleaned the head surfaces and put the new gasket on. I wanted to check and see what difference it made without machining the faces (that and I don't want to separate the powerhead from everything else if I don't have to). The compression is up to 50 psi on both cylinders (I checked the gauge...

    Thank you for the replies. I have the head gasket ordered and I will try getting the surfaces flat.

    Water leaking Yamaha 25

    This might be nothing, but I just noticed water pouring from a crease between the cowling while flushing the motor. I barely had the water on, as I've read it's bad to put high pressure water into the flush port. I think I sniffed out where the water is coming from. This tube with the...

    93 Johnson 8hp low compression

    Might be the head gasket. Top cylinder has a little scoring. Bottom cylinder looks pretty good. I could get a cylinder hone and try to smooth it out. I'm not eager to tear the whole thing apart just yet. I'll can try a new gasket and see how the compression looks.

    93 Johnson 8hp low compression

    First time working on a 2 stroke, J8RETB. I got this motor years ago and never messed with it until now. So far, I can only get it to start by using a drill on the flywheel. It would only run at medium throttle or higher. I soaked and cleaned the carb really well and got it to almost idle...
