I have to agree, 100%!

Jeffrey S: I have used Awlgrip for years, since that is what came with the boat. Absolutely wonderful for toughness and gloss retention, but not good when it comes time to touch up damaged areas. OK on a "workboat" like mine, but if you try to maintain a yachty finish, it is labour and $ intensive. (It can't be polished or buffed - making a repair blend in is a bit difficult)

Recently I have been using another two-part urethane topcoat, Devthane 379.
Very impressed so far, beautiful high gloss and apparent durability.

If air quality and the environment are a concern, they have a couple of water-borne acrylic products that look very promising.
Devcryl 1448 may be applied directly to bare steel and aluminium.
Devcryl 1449 requires a primer.

Obie:
My apologies for thread drift!
You started a very interesting thread about your very beautiful "new" vessel, and I have enjoyed following the various posts. I want to know more about YOUR boat, not lots of boring chatter about how some old fart (that would be me!) paints his boat!
So, I am suggesting future opinions on paint from me will be either in a PM, or in another paint dedicated thread.
Now ............. Howz about some more photos of your new mistress?

kev_rm 02-27-2017 01:56 PM

Sweet!

Jeffrey S 02-27-2017 04:21 PM

I agree - more pictures of the new steel boat. Sorry for the discussion of paint for other boats...

Obie 02-28-2017 09:59 PM

You guys are awesome.
I just got to my computer for the first time after getting home. Today was a long day of cleaning. Worked from 6 am till 6 pm. Tomarow I will get a few more photos up.
I have thuroly enjoyed reading all the post about paint, it is a very important topic for all of us. So don't feel bad. It's now on this thread and I can review it often and easily.

Ok I have a serious question to put out there.
Part of my electrical is 36 volt. Most D.C. Panels are rated for 12, or 24 volt D.C. Or ac.
I am guessing here but I think the same breakers work perfect for 36 volt also? I wish they were rated in watts instead of voltage and amps. Would a person even (me) want to adjust for the higher voltage? 12 volts at 10 amps is 120 watts, so 10 amps at 36 volts would be 360 watts. So should the breaker be a 30 amp breaker. For 10 amps at 36 volts?
This one is not for the novices.

Breakers are current limiting devices, so operate the same at 12, 24 or 36vdc. Regardless of the voltage, amps are amps. But as you go up in voltage, there may be limits to which the breaker contacts are designed to handle. Higher the voltage, the more likely it is for contacts to arc on opening. Check the specs of the breakers you are using.

A few more pic as from today

DC breakers are far more robust than AC breakers .

If the installed units show DC on the info cast in , you are home free.

Is that a pneumatic transmission and throttle control I see in the pilothouse?

Ted

Obie 03-02-2017 09:47 AM

Hey ted yes it is. I don't know anything about it, are they junk? Should I chuck it and go cable? This is my first time with this stuff and I have not got air rusher to it yet.

Pneumatic is great. Lots of commercial boats use them

Closer pic any advice would be great

O C Diver 03-02-2017 10:20 AM

If you are using the original transmission, engine, etc., I would hook it up, give it a try, and see how you like it. The one I used worked fine (from memory of 35 years ago). My one recollection was that they shift slower than cable as you empty one chamber and pressurize another. The boat (110') had quite long lines which I believe added to the delay. If everything works, play with it. Not sure I would spend much money on it to restore it. The air compressor, cylinders, and controls are just one more system to maintain.

Not sure if you got the dd's running yet but I bought a co2 fire extinguisher and kept it handy in case my dampers failed. Also good to have around all the time working on the boat

If you have a pneumatic gear control I'll bet you have a manual (not hydraulic) gear.. if so the alternative to pneumatic is not cable for the gear, it's a skookum lever system, takes quite a bit of force! Cable will work fine for the throttle, but keep the pneumatic F-N-R if you have a manual gear!
The old Gray Marine supplied manual gear on the 6-71 was good, will last forever.

The Gray Marine I had in one of my charter boats had a Twin Disc manual transmission. The engine was directly under the pilothouse so a large lever came up through the floor. You pushed it to stern to go forward and pushed it toward the bow in go backward. Only transmission I ever disassembled. Had to replace the throw out bearing and clutch plates.

I think it was Marco in Seattle that used to make an electric push button
control for those manual transmissions. The shift was FAST.

I believe it was Bill Naud that built the systems for the Marco boats.......ancient history.
