Re: 18hp Johnson 1963 white smoke and full choke

Congrats on getting it started again. The muck in the barrel is normal. The nostril you show in picture is not the main exhaust only for pressure relief at idle. Check that the carb is wide open when stator plate is at the rotation stop. Mine wasn't. Made a huge difference in idle when I fixed that....

Re: 18hp Johnson 1963 white smoke and full choke

Yes that is it. You might want to spend $5 more & get a mid-grade one, as you will use it for many things in the future. The entry level items just don't hold up in my experience.

Re: 18hp Johnson 1963 white smoke and full choke

If you have an ohmmeter you could check that the grounding wire at the coil isn't grounded until switch is pushed. On mine, the carb throttle linkage was set wrong, I reset it so that throttle plate was wide open when the stator plate was at the stop (it was a long way from this). With the carb misa...

Re: Float pods , hinged

That gap could cause some turbulence. Maybe install an overlapping panel? You can temporarily attach it with adhesive caulk. Doesn't even need to be metal.

Re: Float pods , hinged

Just saying that if it can break off, it will happen to me. We boat in adverse conditions & have been pinned against a log jam with 10 mph current, etc.

Re: Float pods , hinged

Nice idea! You might want to connect the top better, so if you hit something sideways it won't tear off the hinges.

Re: Roll and Tip- what am I doing wrong

Kibitzing here - If you add hardener, wear an activated carbon filter mask, even if brushing.
Hardener is made from isocyanate & is really bad for you.

Re: 1987 Lund Tyee 5.5 Restoration

Knock test for transom rot is a good one. Also if it doesn't flex when you tilt the motor, that is also a good sign.
Are you still in the Mississipi valley? I am orig. from Quad-cities & have great respect for 'ol man river.

Re: 1987 Lund Tyee 5.5 Restoration

Looks like you got a diamond in the rough there. Big & little merc brothers! I had same 80 hp merc, don't be surprised if the carb floats are gas-logged. My boat had pinholes in the keel (from beaching, worn thin). So check that out as a possible leak point. Also check the transom for rot, I rebuilt...

Re: Motor about to go into storage for a few months. What to do?

I have heard that it is best not to run fuel injection dry.
Could be a motor-myth, but seems logical to me.
I would add stabil to non-eth gas, run it long enough to get that into the injectors, fog it & then get a plane ticket to Florida. Winter bad!

I vote coincidence. Maybe there is a 2nd smashed (hot) wire.

Not sure of the % of water but have seen lower units crack from freezing. Going to drain & refill mine before winter.

Re: 18hp Johnson 1963 white smoke and full choke

I just got same motor, The float/needle clip was not in place so needle was stuck open. Take another look at it, also check float level.
