Man that looks great! Your going to be ready for the spring pre-spawn eye fishing for sure at this rate. I'm already looking forward to February here on the Columbia River.

Keep up the good work, your at the rewarding rebuild stage now.

Re: My Walleye Project - 70's Sea Nymph SS160 1668

Just a few things to think about. To stiffen up that forward bulkhead in mine, I cut a couple pieces of 1" angle aluminum and riveted in vertically from top to bottom on the forward side to add some needed support. You can see I have 1 of them in on the pic below.

I also added a support cross member of angle between those 2 pieces of light angle supports for the deck below the casting deck. Reason being is that's where my big trolling motor battery is, gear and front livewell.

You'll also find that unless you spent big money on marine grade 7 layer 3/4" for the front casting deck and even then it would need to have some supports under it because of the huge span and the hole cut for the hatch will make it weak. 2 choices on that one, install "I" beams underneath to the lower deck or bridge the span with some angle aluminum running from the from support to the bulkhead. My SN even has another support beam I'm not seeing on yours that is between the front support and the bulkhead. (see pic below)



Let me know if any of that doesn't make sense to you.

I do see the larger bulkhead vertical support. Great idea thanks!

"I also added a support cross member of angle between those 2 pieces of light angle supports for the deck below the casting deck.

That beam that you are not seeing on mine, is because that was cut out as well. I have it, but its too short to span that gap now :facepalm: , so I will need to make a new one. And then probably use cross members between bulkheads like you mentioned. Seems the best way.



As for cutting out your main casting deck, would you mind just shipping me your template? You will? Ok thanks Rob! :) LOL

Re: My Walleye Project - 70's Sea Nymph SS160 1668

Brought a third boat home yesterday... Lets just say it needs to be gone by the end of the weekend.....:boom:


Unsure of the year, but its an aluminum hull Duratech!



Bought it for this specifically, with its steering and controls. 1978 50hp Johnson. 119 and 125 compression in the cylinders. Power head coloration was perfect. Spark plugs looked normal. Fired up for a few seconds after using some brake clean in the cylinders last night....so it runs. Will be doing an overhaul on this on the necessities.



When I got it to run, the prop spun - in neutral. This gives me some worry. I was told when I called the guy back today to ask about it, that this is an "electro hydraulic shift" and it needs a special "Johnson Electro hydraulic Gear Lube". "The gear lube is probably low, which may be why its stuck in gear. It has to be running to switch it out of gear." But he promised be mulitiple times everything is in working condition. After some forum searching, I believe the correct term is Hydro Mechanical?

So I guess it needs some tinkering. I will be starting a motor thread to get to the bottom of this, and for all my other questions.


I did see "F R" in another forum say this:

Stuck in gear doesn't mean anything. The Hydroelectric motors are ALWAYS in forward gear if not running. It has to be running in order for the shift to operate. Look for something else causing your no-crank problem.

Sigh...

Re: My Walleye Project - 70's Sea Nymph SS160 1668

In addition, the boat came with 4 nice seats(covered in crappy boat coats) and 4 nice pedestals which I am in need of for the SN, I was happy about this. One which ripped itself out of the rotted floor on the trek home. 2 metal gas tanks. Couple rod holders. Bilge. Aluminum paddle. Older Lowrance Unit. Galvanized trailer. 30 gallons of snow...and a brand new looking StarCraft Steering wheel!!!












All for $380. Not a bad deal. Im going to strip it and try to sell the hull with the trailer. or scrap them. Im not sure of the condition of the hull yet, but he said its pretty rough. Either way.... to get some money back.

Another case of chronic MBS. Just don't look the old tin gal in the eye or you won't be able to pull the trigger on her! That's a great deal, you got your moneys worth there.

One thing to look into on your 50 Johnny, in 1978 they didn't make a 50 or have that hood with the emblems like yours. Also I believe in 1976 they wen't to straight up mechanical shift with linkage. Does the motor have it's model number plate on the mount? If I were to bet, I would have to say your 50 is a 1974.

I found a pic of my motor ID plate.

Very good points sir....I will get that model info tonight and post it up.

Yea scrapping will most likely be $75-100 and the trailer is nothing for scrap---hope to CL it first.

Yeah, I'm not a motor pro, but I think they phased out the hydro-electric shift in the early 70s (72 or 3-ish). They were known for being buggy and having some problems. Try to find that model number and we can get to the bottom of what you have.

Re: My Walleye Project - 70's Sea Nymph SS160 1668

You guys are right! 71. Guess I shouldn't believe everything I hear. Thanks for checking in guys....PMC I'm diggin your SN!




So I hope this motor was a good choice. At least it should be for the money.

I man-handled it off the Duratech transom across my garage.....I wish I could watch that over again from a spectators point of view.






Got the boat fully stripped as far as I'm concerned.



Neat little transom on this boat I thought.



Some interested peeps on the CL, should be gone tomorrow!

Nice, I'm hoping the steering and controls are all in working order. Hey don't go busting anything lifting like that, remember I had hernia surgery earlier this year from doing stuff like that. These guys have some great parts support for the older Johnny motors.

^^^ +1.5 for the lifting advice.

Had 2 abdominal hernias repairs already, and will likely need a 3rd sooner then later. :mad: Hard to ignore the symptoms & tugging after the 1st 2 go arounds.:embarassed:

Hope the orphan tinny lands in a good home.... Be sure to refer them here. Duratechs are usually constructed fairly stoutly, and I like the ones I've seen while hunting down info about my Duracraft.

Steering looks brand new. The PO had mentioned he had it upgraded in the past. Its sweet!

I will do my best! The PO said it wasnt sea worthy...though I have not inspected. This sea nymph Im restoring was most likely worse.

I am kind of falling for this duratech, but we could never make it. We just dont have enough in common. Plus, if the wife found out, it would be the end of both of us.

Alot of the offers I have been getting are most likely from guys going to scrap it.... :( Oh and hernias....yea I probably should not have done that by myself, but I was my only helper. I will not do it again guys, I promise for your/my sake. Thank you guys for your advice on those!

Re: My Walleye Project - 70's Sea Nymph SS160 1668

I ended up getting off the duratech:

  1. 1971 Johnson 50hp motor that fires
  2. Controls
  3. Teleflex type steering
  4. Four boat seats in nice condition
  5. 4 pedastals
  6. 2 metal gas tanks, 3-5 gallons-ish
  7. Lowrance FF and transducer, etc
  8. 2 rod holders (1 alum, 1 plastic)
  9. 1 laminated map of Lake Erie
  10. a workout



SN:
I will be cutting the transom shape out tonight, then covering it in coats of spar urethane. I have been toying on what to do with the decks, livewells, seat positions, etc. Guess I need to get the decks templated(word?) and cut first....which will be fun.

Transom dry fit. Perfect. Put a few coats of spar on it too.





Oh and bye bye Duratech!

Re: My Walleye Project - 70's Sea Nymph SS160 1668

added more foam tonight, along with a couple angle brackets to hold the casting deck support bulkhead. also cut a deck piece to put under the casting deck / over the bow foam.




Also, my bulkheads and hull interior look like poo. Any ideas on the best way to clean this up?

As a fellow tin addict and river rat, I sure hope to see the walleye machine down on the river this spring. Those waldo's wont stand a chance with this new rig. Seeing the parts boat leaving must have hurt ya a little bit, a guy can never have enough river boats to enjoy springtime walleye on the big D. Hopefully you have yet another back up boat in case this one isn't ready by April??

I have heard that even in the D. River it can get really rough. Any concern about that? This might be a good boat to make sure that you have the right amount of proper floatation foam in.
How about splashguards (wave wackers)?

River isn't too bad, but it is a mile wide in some areas and can get a bit rough (1-1.5 footers) there are jon boats down there fishing on a regular basis. If it's that windy most fishing is bad anyways so not really too big an issue. Boat control is the entire key to fishing (vertical jigging) the D. Hand lining is another method, (trolling in a river) so again boat and speed control are key.
Foam is always important in my book, on any body of water.

Looking good man, nice job on the transom too.

On the cruddy aluminum, after stripping down, cleaning, repairs and gluvit, I used JVV's best to remove the gray oxidization. With the hull bare your able to use the cleaner, scrubbing tough spots and then rinse out with the hose. With foam and decking in already, I'm not sure how easy it would be since all of the cleaners have to be rinsed off afterward to keep from leaving streaks.

Edit: I found a pic that shows how well that JVV's works to clean the skin.

I hope to have her done in time, but if not we will be down there anyways. We normally fish out of by buddy's boats, so either way we will be jigging! You are right GBF, it did hurt a little letting the duratech go, but the $200 cash made me feel much better... She was a little rough, both a go0d hull overall. A couple Ohio-ans will enjoy her.

The D can get borderline risky with wind and freighter traffic/waves---but as long as you know what you are doing you can manage. I have never been worried, even in my one friends 16 ft flat bottom, so this SN will only give me more of an advantage being a V hull....and in his boat we have fished in some really bad wind. (Seems to be bad wind every spring weekend I fish)

GBF said it here, when it is that rough, we stay home. I have tried to fish in that wind multiple times but have learned now to just wait for a better day. If you cant keep your line vertical, it may as well not be in the water. Even on those 30 mph days, we are safe in his jon boat. I feel like I have a good amount of foam in there so far... I may still be able to fit more once I map out my "under deck" areas in the bow and stern.

I will try the JJV's...carefully. My rinse will be with a water soaked rag instead of a hose. Yours looks very clean!
