'56 Johnson Javelin Shift/Throttle problem

Re: '56 Johnson Javelin Shift/Throttle problem

I'm late to the party as usual but, all things considered, I believe you have to declare this project a victory! Taking a motor of unknown history, overcoming PO-created issues, rebuilding the LU and accomplishing your mission with the family in the short span of time since July is nothing less than remarkable. Thanks again for letting us be a part of it.

Please drain the gearcase and refill it with fresh oil just in case there is some water in there and fog those cylinders also before you settle in for winter. Give us a link to any new threads so we don't miss the "rest of the story". Good luck!

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!

Kath. it is because you keep stepping forward after the setbacks that inspires people.
A married mum with kids and working on this motor yourself?? fantastic
dang it took me 10 years to train my ex gf how to check the oil in her car :|
the world needs more women like Mrs Kath. actually the world needs more people in gen like Mrs Kath
Having said all that. since im not working, i think i will now go out and check the oil in gear case on mine.

Well at least it was any easy diagnosis! LOL. No big whoop. Just get it rehubbed, or find another prop. Thankfully, the new prop will slide right on and you'll be off to the reaces again in no time. No really. I promise this time Be sure to take a vid of your first major VROOM-VROOM so you'll have proof for any/all naysayers. Happy parts hunting.

Re: '56 Johnson Javelin Shift/Throttle problem

I'm not sure what kind of prop I need, not sure about the pitch? I looked on ebay under Johnson evinrude props and was a little shocked at the $90 prices and new ones on here are about $100 too. I have two marine places within 45 min. of me and I'll call them tomorrow to see how much it will cost to re-hub it instead. Will that be a good enough fix or should I bite the bullet and go for new? Is it safe to buy a used one on ebay for a cheaper price or am I just asking for that to happen again? Also if I re-hub it will it be more likely to fail again? (Gotta admit...I DO like to drive fast!!!)

Having one of these old props re-hubbed is economically desirable and it should last for another 50 years unless you hit something solid. Your insight to buying one off eBay or elsewhere is on-target because they are all probably nearly as old as yours and subject to the same hub failure due to age. From the parts catalog, I could only find one OEM part number for a prop (0380637) but I could not determine diameter and pitch. That indicates to me you may not have many options. MarineEngine.com says they have two in stock and listed it for $145.00. Check closely on both ends of the prop and both sides of each blade because there should be a part number and/or size stamped into the aluminum.

EDIT: The iboats.com store has a couple new ones made by Michigan Wheel for under $100.00.

Re: '56 Johnson Javelin Shift/Throttle problem

my 56 came with an adjustable prop!i will have to dig it up from the garage to give much info on it but it was the cats meow for dialing in older johnsons and evinrudes.they are not seen everyday.omc product from the 50,s ,very cool.

Re: '56 Johnson Javelin Shift/Throttle problem

The size of prop needed is based on your boat, activity mostly done, and motor.

The most important thing is that the WOT RPMS fall within the reccomended range, which is 4500 RPMS at WOT for your motor. If your current prop gets you to that number, I would not change diameter or pitch. For every pitch you increase, your WOT RPMS decrease by about 200 RPMS. For every pitch you decrease, your WOT RPMS increase by about 200 RPMS.

The prop installed at the factory from new is the companys best guess for an all around sized prop on a standard sized boat, as they had no idea what the customer would be using it for, nor what style of boat it would be installed on.

Your prop looked decent, the cheapest route would be to just get it rehubbed.

Re: '56 Johnson Javelin Shift/Throttle problem

+1. Probably cheaper and easier to just get it rehubbed. Any prop shop should be able to do it for less than $50. According to this link, your prop's part number is 375790 (pg. 17, part #40), but it doesn't list the exact pitch. As previously stated, the rpms are really the most important factor. As long as they're within the acceptable limit, then you're getting all you can out of the motor. You can buy cheap little aftermarket tachometers (aka Tiny Tachs), but most folks just sort of do it by ear/feel. Use some vids of other motors like yours running to see/ear what you should expect.

Re: '56 Johnson Javelin Shift/Throttle problem

Called 2 marine repair shops within a 45 mile radius to me and neither of them do it, said that they don't know of anyone close that does the re-hubbing. The nearest is in St. Louis which is 90 miles from me. So I think I'm going to go to one of the places 20 miles away that has a lot of old parts and see if I can find another prop like this one. I hate getting another old one but I don't have much of a choice if there's no one to do the re-hub work. If I can get a prop for around $20 or so, I'll probably get two just in case. That's still cheaper than brand new. It's a gamble though.

Re: '56 Johnson Javelin Shift/Throttle problem

id look into the cost to "ups" it to the prop shop, that way you'd be (should be) good to go without worries.

Re: '56 Johnson Javelin Shift/Throttle problem

Thats wild, any reputable marine mechanic should be able to get it done, or be able to send it out to get done for you. This is a fairly common issue. Is there no Johnson/Evinrude dealer near you?

Would hate to see your poor mother floating around the lake again!

 

[KathyD19]

Re: '56 Johnson Javelin Shift/Throttle problem

NWcove that's a great idea! And yeah, I was surprised when both places said that no one around here repairs props, said it was kind of a "dying art". Of course I'm in land-locked central Illinois so there isn't a huge demand for boating here.

And now, I've made a Youtube account and posted my first videos ever so you all can see me "in action" :facepalm: My brother was video taping when the prop spun so you can hear it/watch it as if you were right there with me. Notice my tight/fake smile as I'm cussing in my head wondering what the *@&#)(%# I did now and how do I fix it to save face. I could only assume it had to do with the shift rod coming undone or something since that was the last issue I was working on. My poor mom looked so cold in the back! Awww! Here's the link, if you don't laugh at me too badly!! http://www.youtube.com/watch?v=FUn5lYySQiU (there are 3 one minute videos that he took uploaded there)

Re: '56 Johnson Javelin Shift/Throttle problem

"....am I gonna be paddling?" Gotta love brothers! The motor looks sweet on the old boat! It was idling along nicely before the big burnout. I agree that it might be cheaper and easier to simply mail/UPS your prop to a decent shop and have them send it back. Hang in there!

Re: '56 Johnson Javelin Shift/Throttle problem

What size is your current prop Kathy? May have found something for you.

Re: '56 Johnson Javelin Shift/Throttle problem

kathy though its proably the hub i would like to know if when you got back to the dock and lifted the motor did a piece of wood or anything pop out from the area of the motor?happen to me a few years ago and at first i thought i broke a shear pin but all was kosher and then i seen a piece of drift wood floating a couple of feet away chewed up, problem solved,still running a ok.

Re: '56 Johnson Javelin Shift/Throttle problem

I didn't hit anything in the water, 82, I'm sure of that and the prop definitely looks bad! (I posted pictures on the page before this).
High Trim...how do I find out what size the prop is?

sorry didnt see the pics ,that hubs toast.there are only 2 props made for that motor ,you can get both here at iboats if you want .most props have the diameter and pitch stamped on the main hub outside ,for example 10x10p.

 

[KathyD19]

Re: '56 Johnson Javelin Shift/Throttle problem

The only thing stamped on the prop is "AMC 383 Michigan"
