    Posted: October-10-2023 at 6:12am
Starting my restoration project: 75, Southwind 18.
As a winter project, I purchased the above mentioned to fill in my long winter days. I’m already gotten any things on this boat even before beginning restoration.
This will not be a highly detailed extravaganza. It will be more of a picture tour as I go.

So far as you can see, we are removing the motor.

Just a couple of pictures to show progress. I haven’t had too much time to work on.

I haven’t spent a lot of
time working on the boat. Got the port side, stringers uncovered. Surprised to find they are pretty good shape. Wood solid, but black were water entered the motor mount bolts. Still no water soaked foam.
It seems a shame to tear the boat completely apart to fix something that’s not that bad.
Exploring options.
Comments, welcome.

I just learned something valuable.

I will try to post later

Making some progress. Got everything pretty well cleaned up from the front of the motor cover back. Everything from the front of the motor cover forward is going to remain untouched as it does not seem to be wet or rotted at all.
Stringers will not be changed at all either. Unfortunately, I have cut the top off of them and they’re all exposed so I need to do something with that.
My thought is to run nuts and bolts all the way through to attach the stringers back to the fiberglass, very securely and then fiberglass over that.
I had another thought, the 2 x 3 channel to the outside of the stringers. I could fill with some of that material that similar to Seacast to strengthen the boat up. Should the stringers ever go bad they will not need replaced.
However, I talked to Tech guy at the fiberglass distributors,he said that would probably be two stiff.
My plan is to rebuild the floor supports back in with Coosa board and fiberglass everything really well so that nothing ever gets wet anyway. Correct Craft did a pretty good job doing that, except for the holes where the motor mounts were on the stringers. As for the rest of the structure, holding the floor up, really wet and rotten because they did not seal the floor around the motor cover.






Arsenal of saws I used.
I decided to clean up all the mold in the boat, so I got it kind of wet. There’s a couple fans drying it out for the next couple weeks before I begin reconstruction.
I am currently trying to decide what material to use.
All seems pretty simple now.
I have the interior to do something with as well as the exterior cleanup.
Oh ya, picked up my 350 short block today.

Interesting project, glad you are sharing the pictures.  If you have any of the hull and dash add those as well, curious to see more of the boat.  I would have thought Ford 302 by 1975, not the OMC, not that I'm all that familiar with which engines which years.  I assume that's a 305?

Oh of course, I should have realized it was the same SW.

Could forgetting this possibly be related to my problem of not being able to remember what I had for breakfast? Smile

It actually had a 307. Came to find out the block was cracked. So we’re gonna put a 350 in it.

Your boat is bad ass. Gonna be super sweet.

Nice looking SW, that's going to be a fun boat.  Great idea on the 350, now you only have to decide how much hp you want out of it.

Progress photos
Next I clean up the foam and grind all the surfaces. I’m going to fiberglass too. Then most of the nasty part is done.

Super sized Ski Nautique seems like an accurate description! These Southwinds are pretty neat! Deep hull and a walk through windshield, two things I wouldn't mind having. You probably won't have as much water washing over the bow like in the older Ski Nautiques. Shocked

Hi Den,
from the inside the hull does look identical. Stern is a bit different though.
I have to admit that I've been spying on your posts to see how your SW's (and by extension our BFN's) floor is constructed Big smile

Keep watching next week I hope to start reframing the floor supports. I am collecting material right now. Going with Coosa board and epoxy resin from Total boat two to one. Course of fiberglass mat and some thickener.
This is all new to me, but I think I got it.

I am currently having a difficult time, finding the camshaft that I want. Not too many people are making them for right turn engines. I just found another source, possibly in Texas. Some guy has a shop where he grinds them for a rebuild company.
I hope to get a hold of him on Monday.

So........what is this camshaft that you're looking for?

Reverse rotation flat tappet? or Reverse Rotation roller?

What vintage short block do you have, one with a 2 piece  rear main seal or a newer one with a 1 piece rear main seal?

The one on the right is available from Melling and I have it on order. I have not found anyone else that makes a right hand turn. The one on the left has the specs I desire. I need to find someone who can make that. I think crane for an extra hundred dollar charge but I have to wait till Monday to find out.
I will use the one for Melling, but I would prefer a little bit more power without sacrificing idle. I plan on degreeing the cam should I receive it to assist idle.
(the lobe separation on the melling is really 110 instead of 108)

There are a bunch of little voices in my head, mostly all saying that you better make sure the guy you talk to knows you want a cam that works in a Reverse Rotation Chevy engine. Wink

That Comp Cams example above might have the numbers you're looking for, but those little voices say that it's for a Normal Rotation Chevy. 

Are you all set with the part numbers for a Reverse Rotation rear main seal and timing cover seal?

Thanks Ken for saving the day. I knew about the rear main seal running reverse, and the people that supply the short block did that hadn’t thought about the front seal.
Yes, for the camshafts, I spoke to the Melling rep and that’s how I know that one is reversed right hand. I also talk to the competition cams rep and that’s how I know they do not make one that runs reverse. Maybe tomorrow I’ll find out some good news. Thanks again.

This is what I believe the original wood underneath the floor looked like. The repaired before actually used concrete, mortar and Bondo to fix the very bad part. I’m not positive this is exactly the same. Parts are just sitting there for now. Not fastened yet.

I'm getting dizzy, cross eyed and banging into walls after looking at your looong run on pictures.

Could you help save the walls and hit enter twice after you paste each picture so it leaves a space between them? Wink
