Re: 1979 Sea Nymph FM 161 resto

This pour in foam is everywhere and sticks to everything. Even before I knew about limber holes it is painfully obvious there is no way this design would ever drain. The pressure washer comes out to try and blast off the last of the foam, clean up the bottom a bit and see if can blast under the ribs to open.....the limber holes.

Starting to get a bit concerned about drainage down the road. Not a lot of room under the ribs and not comfortable drilling holes thru the hat channel, especially at centerline as it is already cushed from forming die....

Will keep cleaning for now and do some searchin on other rebuilds.

Yup, now I got it.

I think that was my evil twin brother Labatt that stole my password last evening. He isnt the sharpest tack !

That's funny... Yep, I thought that a late night, 4-post bender may have been fueled with some Christmas cheer... No worries...and cheers!

Transom Time:

By this time in the process have lurked enough to expect the mulch. I have been picking at it with some pointy tools and seems solid.

Matter of fact, It seems really good so sand a bit (lighter area in pic) and looks good.

So, off with the obligatory 100 screws / bolts. I know when the cap comes off the top it will be mush....

Hmmmm, no mush. Solid.

So lets get this thing out and I am already looking up to see where nearest tree limb is but lets just see what happens.

Nothing, wont budge. Double check for more screws and yup, guess my crew didnt hear the order to remove the thru hull splashwell drains. Oh, oh ... the crew was off today so dont have to look much further than the author. Dummy.

And so the transom slides right out. No mush on bottom edge and they actually did a nice job making this. There is not one perpendicular edge so everhthing is a combined miter if that this the correct term.

Still going to replace it but maybe clean this old one up and find a home for it in my bar, or as it is known "The Long Oar Bar".

The aluminum cap is not cracked or corroded, beauty eh.

Re: 1979 Sea Nymph FM 161 resto

I have admittedly been over using the wonderful word Limber but looking at the last pic it dawns on me I dont have any limber holes.

But something was kicking around in the old noodle that I had seen before. Some searching and there it was / is. When JAS was doing his 1980 SS 165 Sea Nymph he encountered same situation. As he resolved the Nymph designers said water woud have to go up and over the rib. Beauty part of Iboats eh...its all here.

Re: 1979 Sea Nymph FM 161 resto

I am still catching up this thread but at that time was thinking what do I need to get done before weather closes in.

Leak Test
Wheel Bearings
Engine stand
Storage...can't do it here
plywood for deck to work on over winter

and then some sitting and thinkin. that boat is sure opened up once everything is out....


So start filling her up to check for leaks. Heeding the cautions from others not to overfill, get carried away and bend her up she starts filling up.

not too much now

yup, she's a leaker

not good pic maybe you can see drip line

mark the leaking rivets & seams. flip her over and look closer

not bad I am feeling comfortable with all the info here on rivets. no bumps, depressions, hull looks good. po obviously thought rtv silicone was saving grace and then maybe some marinetex but doesnt look bad

I do some scraping, some power washer blasting and this should clean up relatively easy. Still happy with boat and enjoying the project.

Re: 1979 Sea Nymph FM 161 resto

Goo and paint on the outside just doesn't stop leaks as well as a lot of people think it will.

I'm not a big fan of the fore to aft stringer design in aluminum boats, especially with that light channel design. That's the reason they filled your bilge up with expanding foam, to give the decking the support the framing couldn't.

I suggest going back with a good grade of 3/4" decking.

Yah, I honestly believe that the SN builders had no intention of my boat (or yours) draining out when water went sub deck. I guess they were thinking there would never be water in the boat or they just didn't care. Or both maybe. Bummer eh.:blue:

Re: 1979 Sea Nymph FM 161 resto

Thank you for the heads up. I have found the stickys to be a great source of info. and starting place. Amazing the contributions by folks let alone the organizing. I was able to print off the prints and BOM on big paper at work.....

 

[Streetgang]

Re: 1979 Sea Nymph FM 161 resto

Thank's jig for the review. My shop works in .125 aluminum sheets regularly, fab, weld, etc. so was disappointed while crawling around in the bilge to see the lighter weight alum. used let alone the lack of stringers from gunwale to gunwale....especially when looking at other threads and other designs. So, need to get this thread current and then come back to this for resolution. I would look forward to your feedback when get back to this. Thanks again.

Re: 1979 Sea Nymph FM 161 resto

I get the engine stand plans from sitcky notes and buy up supplies based on the BOM provided. Sure makes life easy. Lay out the boards for cutting. My retired Sandusky pal comes into town and gives me a hand cutting and shooting screws. Close up the garage door, fire up the heater, go at it.

Looks like 2 huge bloodshot eyes watching the work eh.

Re: 1979 Sea Nymph FM 161 resto

Time to check out the trailer hubs, bearings, seals and lube. In the way back machine I worked at a bearing mfr. so fairly curious what will find. Previous mentioned found a lot of old grease on inside of rims so thinking po kept shooting a lot of grease into the hub and out the seal.....

First bearing buddie off and this gray lube kinda just starting to slide out of hub. I dont like that but lets get hub off.

While at bearing mfr. developed good frinedship with fellow responsible for failure analysis. Most of the time it was straightforward:
lack of lubrication & contamination. I saw a lot of failures and came to see how what at first thought was just dark staining was actually the beggining of rust. Under the microscope it was very clear. Also came to appreciate how many different grease were used. I think we had over 50 different types in stock depending on application for the bearings. Keep in mind at that time the synthetics were not in vogue yet.

So dont know if this thin gray lube is synthetic or just cheapo stuff but dont like it. I pull the seal, very cheap, sinlge lip, half case, no garter spring. Bearing cups and cones were made in China and obviously were not original to trailer.

Go to local marine store and auto parts store, all they carry is the same offshore seal and bearing combo.....so thats what it will be.

One spindle show some signs of pitting and staining.....remember what ole Neil said "Rust Never Sleeps". Other spindle was:

I was most concerned about spindle surface where seal rides and after some clean up and emery cloth found it to be acceptable. I considered shaft savers but ended up passing.

New lube, nice and sticky for hubs, bearings and seal surface. Install, adjust and good to go.

I learned that the application for a boat trailer is not a healthy environment. As a fellow mentioned over in the trailer forum, sorry couldnt find him to give him his props, it is just Physics. Trailer boat to ramp...nice and warm hubs, bearings seal......dip the trailer in the lake and a vacuum is created where the cold stuff wants to make friends with the warm stuff in other words get past the seal.

My Pop and bearing friend got me in the habit of checking the hubs an least annually and moreover any time out on the road. After 5 miles or so just stop and touch the tires and hubs. You will discover if they are running nice and cool or if theree is some serious heat building up. If heat get some help soon.

The traditional failure is when the bearing gets so hot it actually welds to the spingle and then boats and trailers all over the highway.

So if you get in habit of checking frequently while on way to ramp, trips let alone annually pulling hub your life will be relatively easy, imo.

OK, another item off the bucket list.

Welcome Streetgang, looking good so far. I'm a Nymph owner and an old Cleveland ('burbs) boy myself, I grew up in Brookpark and Brunswick. I'll be watching your progress and I'll try to help if I can.

Re: 1979 Sea Nymph FM 161 resto

S.G.
Don't sweat the set-backs... Every one of these projects has a few and that's part of the fun...
I'd be interested to see how you fix that gouge in the boat.... Jig and Jas are pretty knowledgeable on metal boats and it didn't seem to scare either of them off... I'd be curious to see what the fix is there... Maybe a spot weld???... (the problem, so I hear, is that a lot of welders get a rash working on riveted boats for some reason)... Nonetheless, as long as it doesn't leak, it will be in a spot where cosmetics really don't matter a ton and only the fishies can see it... So, let's check that one off as fixable...

Now, to the "stringer system" - I tend to agree with Jig that might not be the beefiest set-up for this rig and wonder if that has been re-engineered from the factory.. I think you could fab up some cross braces pretty easy... Little extra effort (and cost) but it sounds like you got access to materials and fab-work.... I'll see if I can find some pics of mine and maybe zoom in and send those to you if it will help... I liked having those (not only for deck support and fastening the deck, but it will also make foam installation more workable whether you stack sheets or use pour-in)...


P.S. The whole limber hole thing (or lack thereof) on these Sea Nymphs is baffling... I could barely get a 3/16 drill bit in there to clean mine out... it won't be long before they are clogged again...


PSSST, fellas, this new guy S.G. knows a ton about trailers... Pass the word that we got a new trailer guy to hit up for questions... Woo hooo...

Re: 1979 Sea Nymph FM 161 resto

Spent some time going through some of SN and Starcraft posts to get better feel for hull construction and some options down the road. Some really wonderful stuff here. Got caught up in Magnumdekes 1976 22' Starcraft Islander thread and great googily moogily that is off the chart.

I/O to O/B
Trailers from scratch
Lifting, flippin, boats, fabricated pieces
wood shop, fab shop, welding all metals and an unbeleivable great boss.

That was fun to follow.

OK, got to get this thread current and get plan set for the rebuild.

I had finished the hubs and was picking some leaves out of the hull feeling pretty good. Leaning on the gunwale just looking over the hull and right below my chin is what in the world but the crack:

All in all not that long. Thinking fairly straight forward to fix, drill some stop holes, probably patch with alum piece from underneath with rivits and 5200 but may as well look over rest of hull a bit closer, especially end of ribs. Nothing comes up.....

I remmember seeing Grandads resto and his boat is similar and his hull crack was in same place although significantly longer.

Mostly what is bugging me is why this happened. No dings, dents, bruises in that area, in or outside hull.

It sits just about halfway between the consol and capt'n seat so maybe some stress from grabbing on, sitting standing ???

Will stroll over to Grandads and review as seem to remember he had an opinion as to why on his hull.

Re: 1979 Sea Nymph FM 161 resto

Unfortunately wont have inside storage for winter so make arrangements with close by place. Only about 5 minutes away so can grab it quick if weather allows.

So as I am unhooking trailer I feel wind picking up and yup, storm rolling in over the lake and off course it has to be those fellows in Michigan sending it our way. turned out to be first snow storm of the year. I know the Canuckistanians wouldnt send it south.

 

[Streetgang]

Re: 1979 Sea Nymph FM 161 resto

I have picked up on the common vibe that is being laid down that it is important to do some sittin and thinkin. As my thread is just about current, weather is here I will some of that sittin/thinkin and get an updated to do list going.

Here is where I sit to accomplish this task:

Wonder if any of the local boys will be able to pick up on the location.....

Cant you just imagine how many lines we can put out when that boom is swung over the side

Please have a Safe and Happpy New Year All.

Re: 1979 Sea Nymph FM 161 resto

I know the Canuckistanians wouldnt send it south.

Yeah, it's their fault... and I blame them entirely for winter!!!

If you've ever watched the Weather Channel they use terms like "Cold Canadian air heading south" and "Alberta Clipper".

My wife and inlaws are Canadian and love it when I spout this kind of stuff.:lol:

Carp,

I grabbed the wrong pic. Still stuck in the thread catch up mode. Meant to use this more current pic

The one with the mighty Cuyahoga frozen over. Common on now, who believes a river that can freeze would catch on fire

just axin
