1981 Aquasport 170 rebuild in Sweden

[larsli68]

If it had been a 19.6 I would have gone and looked at it. I like the looks of the older inner liner better.

I think you'll find that they are the same LOA.  Just sunset an older model and create a "new" model by re-badging it.

Hello Rick, has the inner liner changed? I'm happy with my 170. If I'm up in Stockholm for work and get a chance to go look at it, I might do that.
It feels a bit under powered...

Having a 115hp on my 170.

Even if we have brackish water here in the Baltic, the season takes it's toll if the stainless is not acid proof... I removed these cleats, since they have started to rust.
I'm also removing the teak trim to re varnish them before next season. This time I will varnish also the under side...  To prevent moisture to miss color the teak.

Hi Lars,
Too bad about those cleats but there is a way to renew them and make them a lot more corrosion resistant if you want. I don't know if this can be done in Sweden environmently but you can take them to a plating shop and have them passivated or (passivation) It is a common practice here in the states for enhancing corrosion resistance in stainless steel. Assuming they are 316 or 304 stainless, this is an acid cleaning the removes the surface "free iron" from the stainless and then forms transparent oxidation layer. Many thousands of the stainless parts we produce are subjected to this process after production. This allows them to pass the 120 hour GM salt spray test which is the standard in our industry. Much of today's marine hardware comes from China and is substandard for corrosion resistance without this additional step. You can also have them do your mounting screws, washers and nuts and they will last for many many years without rusting.

Thanks Fitz73222!

I will check with a plating company that I used to use for work if they can do this type of surface treatment.
Cool, thanks! I have more stuff that is rusting, I could get more stuff done.

I took a heat gun and scraped the varnish off from the deck trim yesterday afternoon. I will do a bit more sanding and then varnish them today.

Once again thanks!

A guy I know from sailing has a stainless steel shop here in town. According to his website, he has the passivation surface treatment in house!

I will check with him tomorrow.

Well, It's a gorgeous day here in Sweden. I finished sanding the wood trim, and got the first thinned down layer of varnish applied.
I also heard from my buddy who runs a stainless steel shop with his dad, that I can come by tomorrow and get my rusting stainless steel parts treated.
Really cool.

The teak is looking good Lars.  About the liner, I have no clue about the 196 other than from the catalogs we have in the gallery.
That's good info about getting the stainless treated.

[larsli68]

Thanks Rick!
I'm quite excited I can get it done here in town by someone I know.
Thanks to this great forum, and all the knowledge shared!

I have been cleaning the shed this afternoon... Feels good to get a lot of stuff hauled off to the dump, allowing for indoor varnishing when fall will be here.

Hi Lars,
How did you make out with the passivation for your stainless hardware from the local plater?

[larsli68]

Hello Fitz73222,

I have not had a chance to go yet. A very over busy work schedule... including 950 miles of driving in three days, have prevented me from going.
I did discover that the top part of the hardware had not rusted at all. It was all on the surface that sits against the hull. That surface was course. I'm wondering if all I have
to do is hand polish that surface to a shine, and my problem will be gone? I do have to other pieces of hardware, that I believe are 304 steel, that I need to bring to get treated.

I will keep you guys posted. It's 4:11AM and I'm about to head out driving...

My Aquasport 170 Carolina Girl will get a new home. I bought this Boat shed today. I'm very excited... :)

[RickK]

Nice, Lars!! Do you get the property too or have to move the shed?
How did the chrome treatment go?

[larsli68]

Hello Rick,

The shed is stationary, and I get the property it is on too. I have not got around to get the parts treated yet. I have been travelling a lot for work the past three weeks.

I noticed that the cleat is 90% high polish, but underneath the "feet" it is rough. I'm wondering if I polish the base, the cleat will not rust. I might still go get it treated before I put it back on the boat.

Did you suffer a lot from the Hurricane? It is raining in NC now. Will talk to one of my buddies later today.

//Lars

[RickK]

Ok, so it is a real boat shed - nice.
On the west coast of FL we didn't get much at all, a little rain and some stiff gusts of wind once in a while, the east coast, that is a different story.  I heard back from one member in Palm Bay and he said they didn't lose power and barely got wet.  Haven't heard back from others yet though.

[larsli68]

My buddy in NC has posted several videos of flooded creeks/ roads. The hurricane dumped a lot of water.
It is raining here today... Supposed to be grey all day. I plan to sand and varnish the teak trim again today.
I can't wait to move my boat to my very own boat shed. Be able to keep tools and machines there too, will be nice.
