'56 Johnson Javelin Shift/Throttle problem

Re: '56 Johnson Javelin Shift/Throttle problem

LOL I'm still here, creeping other posts and realizing how very much I still don't know! I sure wish I could be vrooming on the lake but the weather decided it wasn't going to play nice anymore. Went from 83 degrees on Thursday to 41 degrees for a high on Friday and all day rain. Next week it's supposed to be in the low 60's and I'm aiming for Wednesday to take her back out to the lake with my mom for an actual ride going in forward for a change!! Not going to be able to get the picture I wanted to take of all of us in the boat again as an "after" photo to the 1966 "before" picture because one brother is being a butt-head and won't pose for it. He said it's embarrassing and doesn't want me to put it out there on the internet. I don't get it at all but if I can't get everyone in the picture, there's no point. But, weather and health willing, Wednesday I'll take my mom out and I'll post pictures of actual vrooming!

We're still here also, still pulling for you to complete your "mission". You inspired me so much that I spent all day yesterday working on my boat for the first time in six years. Good luck!

Willy, I just wanted to butt in here and say that diagram helped me take apart my control box, learn all about how it works, make the adjustments it needed - because I did actually see where the problem was! and restored my gear movements.

Re: '56 Johnson Javelin Shift/Throttle problem

Wow! I can't imagine that your boat could possibly need any work done on it; I'm sure you keep it in tip-top shape. Being in Charleston, are you able to use it year round? I lived in Greenville SC for a few years...was my favorite place that I lived around the country (lived in Florida, SC and Louisiana before here in Illinois). I guess after next Wednesdays outing, I'll have to winterize the boat and put the motor on the stand I just built until May.

Glad it helped. Wish the internet and this forum had been around 40 years ago when I bought my first boat and motor!

It can get a little nippy and I have never figured out a way to keep my feet dry when launching/reloading the boat so December through February are usually no-go. However, my Dad raised me on winter trout fishing and I have chipped ice off the boat on occassion.

Trust me, there are MANY pictures of him I would love to photo-shop in to get back at him for being a jerk about it!
I guess great minds think alike!

Re: '56 Johnson Javelin Shift/Throttle problem

Well, here's the final voyage for the season. My brother from California (not the stubborn one that refuses to take a picture in the old boat) was in town and wanted to go out for a spin so together we got mom in it and took it out a little bit. It was pretty chilly out today even with the sun shining, the north wind was very strong. He was being a goofball and clutching the floatation device before we even left the dock This was the first time I'd taken it to the lake since bucket testing the shifting repair I'd done so I got there before they did and tested it myself. Shifting worked great, though it seemed a just a wee bit underpowered but I chalk that up to me driving into that strong wind. I DID have a problem with the steering though: the cables came unlooped from around the steering column and I was desperately trying to get it fixed as they pulled up. I didn't want to call off our excursion for something like that so I got them re-wound but they kept coming undone as we were using it. I will need to work on that...probably need to lengthen them just a little bit so I can loop it over one more time or else just shorten it. We did fine taking it out and I gradually got it up to WOT which kind of scared my mom since she was back by the motor so I brought it back slower. Then my brother wanted to video tape us going fast since he couldn't believe the little thing can go so fast and he said "Floor it!" so I pushed the throttle forward (never listen to older siblings..they will always get you in trouble!) and the motor roared happily then continued to roar but stopped moving us forward except at a creep. ??? NOW WHAT HAVE I DONE??? I throttled down and shifted back into neutral then went into forward again and it would go forward but again, only at a low speed, if I pushed the throttle up anymore, it would rev higher but not go any faster. So I headed back to the docks. My mom and brother were so disappointed that the ride was over so soon but I didn't want to get out any further and not be able to get back with my mom in there. I was SO embarrassed. When I take it out alone, I usually do fine but every time I've taken another person with me, something goes wrong. At least they got to ride in it a bit. I would like to address this latest issue if you guys have any clue as to what I did this time? I'd planned to store the motor on it's stand in my garage and take the boat to our family's store warehouse for winter storage after today's outing but I think I should take care of this problem before doing that. What is wrong with the old girl now??

Re: '56 Johnson Javelin Shift/Throttle problem

If it werent for bad luck, youd have no luck at all eh Kathy, lol

Sounds like nothing serious, either you have a shear/drive pin issue, which is easily checked, or you spun your prop hub.

Pull the prop and inspect everything first. Ensure the pin is not sheared or missing. When tightening, hand tighten the nut, then tighten it further until a hole lines up for the cotter pin.

If the pin is fine, likely your prop is to blame. Draw a line across the hub and prop, then run until you hear it rev. Then inspect, if the lines are now askew, as in they no longer line up , the hub is spun and will need to be re hubbed by a prop shop or a new prop bought.

Glad you got out for a final trip, all my boats are now tucked away for the winter.

Re: '56 Johnson Javelin Shift/Throttle problem

Hello again Kathy. Sorry for the starts and fits. All part of the sea trial experience I'm afraid. Best not to take other folks until you've taken your own boat out 3 times in a row with no issues. As you found out, things can get real hairy real quick. Once we've got this issues squared away, we'll work on getting you a kill switch so that you, or anyone else can stop the motor at the touch of a button and/or if you should go overboard. Now onto the runnin', but no goin' issue at had, assuming you didn't get a violent jerk, like when the clutch dog was bad, then it's either the shear pin and/or a spun hub in the prop as High Trim stated. Thankfully, both are a quick, cheap and easy fix. Shear pins are just a short length of brass rod that is designed to fail if you hit a submerged object in order to prevent damage to the gears. To replace mine, I recently bought a 6' length of brass rod at ACE hardware (<$10) and just cut a million shear pins to length using a bolt cutter. I think it was 3/16" diameter, but just take the old pin, or use a drill bit with you as a guide. The hub in a prop is also designed to fail should you hit something while underway. Most motors use either a shear pin, or a hubbed prop with a stainless steel "drive pin", but there's not telling what combo is on the motor now. You can use a brass "shear pin" with a hubbed prop, but you cannot use a non-hubbed prop with a stainless steel drive pin. In other words, you need one component that can/will fail should you hit a submerged object. To find out what happened in this case, simply remove the prop. If the brass shear pin comes out in pieces, then there's your problem, however if the pin is intact, then follow High Trim's procedure for checking the hub. If the hub is spun, you'll have to take the prop and have it rehubbed and/or buy a new prop. Both are about $40. Most folks keep several shear pins and/or props on board in just suck an event. Here are some great links regarding your controls too. You must get those ship shape before your next outing. You've come too far to loose you now The good news is that the motor itself, fired right up, idled well, went to WOT and shifted as planned, and everyone made it home in one piece. Good luck. Keep us posted.

EDIT:

looks like your motor uses a "drive pin" (#302566) (pg.16 & 17) rather than a brass "shear pin", which means you should have a hubbed prop. You can look or new/used props on ebay.com, marineeningel.com, aomci.org

Re: '56 Johnson Javelin Shift/Throttle problem



Uh, I don't think the prop is supposed to look like this...with black rubber squeezing out like melted cheese. Shear pin was intact and fine, so diagnosis is spun prop, yes? At least the boat mechanics will be slow this time of year. :facepalm:

^+3!

Re: '56 Johnson Javelin Shift/Throttle problem

+3?? What does that mean? The amount of bonus points I get for having a cursed boat?

Re: '56 Johnson Javelin Shift/Throttle problem

I?m late getting into this thread. I have just read it all and reads like a true thriller! All of the small issues have been dealt with in turn with valuable input from all the members. This is just how it is supposed to be.

As for spinning the prop hub, it would have let you down sooner or later anyway. By running wide open you merely hastened the failure right at the end of boating season; good job and impeccable timing! By running WOT and forcing the prop hub failure you can see that the phrase ?racing improves the breed? rings true.
Congrats on your success with this project thus far (as it has turned out to be). Also, thanks to all for sharing.

Re: '56 Johnson Javelin Shift/Throttle problem

Hey Kathy...

Props to you on getting this engine to where it's at. The spun hub is bad luck, but good luck that it happened so close to the dock . It's a small set back that's easily overcome.

You've inspired me to go farther than I've ever been with my '58 18HP... and many others here on their engines as well I'm sure.

By the way, ^ means the thread above and +3 means they're in agreement to that thread "add three" times I think... lol

 

[HighTrim]

Re: '56 Johnson Javelin Shift/Throttle problem

Yeah time for a rehub.

Not the worst thing that could happen....

That being said, I love the look of your setup. Sweet. However, I think Ill admire it from afar!

Re: '56 Johnson Javelin Shift/Throttle problem

Awwwww....High Trim! You stinker! I guess it won't be perfect until H.T. is willing to come aboard!

 

[KathyD19]

Re: '56 Johnson Javelin Shift/Throttle problem

Big Jay-I can't believe I inspired anyone from my "one step forward, two steps back" thread but thank you so much for the kind words! I really believe the old motors (and heck, most other old stuff) were built so much better. Good luck with your '58...wounds like a great winter project!

TN-25..."By running wide open you merely hastened the failure right at the end of boating season; good job and impeccable timing!"

So it WAS all my brothers fault! Ha! I knew it!

Thanks for the compliments...tis a work in progress which may just outlive me!
