Priming / painting engine block

[Cap'n Chaos]

After 3 weeks of soaking the driveshaft/crankshaft area with ATF, Deep Creep and 2-stroke oil...tapping, jiggling, a little bleeding and a lot of sweat... I've managed to get them seperated.

My question is regarding paint / primer and matching OEM colors, specifically for the engine itself... although I'll probably end up just repainting the whole thing.

I've read that MAR HYDE self etching primer is good, (I think it was Ezeke who posted about it?) but will that withstand the heat from the engine or do I need a different primer? Or should I just buy some and paint the muffler on my lawnmower to see how it holds up to some HEAT?

Also - where can I find a paint spec / color # to match the OEM paint color? I was going to take a small chip to (someplace I haven't found just yet) to match it but there are 2 different shades of blue on it and I don't know what is original and what was "that looks pretty close" touch up rattle can paint that is peeling off...

This is for my latest undertaking... a salty "old" 1972 18hp Fastwin (18202)

I think any sef etching primer will do the job for you. It's important to remove all grease and oil and lightly sand anything you can. Try www.nymarine for the correct paint color.

oldcatamount - thanks for the link...

I found out that it could be one of 2 colors:

"White" 1964-76 No way it was ever white
"Light Blue" 1971-77 light blue looks awful dark to me

A few pics in case anyone wants to see what I'm up against...

I think I have the right colour for you .. I will take a pic of the ol motor and see if I can get a paint code for you from a friend who does paint

Re: Priming / painting engine block

Rick... That would be great, thank you.

I didn't get a good pic of the paint color, mostly what I was trying to fix. Odd that I didn't seem to find any greenish/yellowish zinc chromate under what is coming off the engine...

See attached pic for a better shot of the what appears to be the OEM "Light Blue". Looks a lot better than the dark blue/purplish color that was used over it.

Re: Priming / painting engine block

Personally, I hate that color.

I know what color its not though! (1963-1969 Evinrude Polychromatic Blue)

I scanned the paint options from the Evinrude parts book for you:

Page 1

Page 2

Green Primer is # 0777172
You can choose the color you want and order it from boats.net for $8 a can.
The J/E Paint is gooooood stuff.

Dont buy the muller crap. ever.

here is my 'painting' page

If you have a part with enough "good paint" left on it, any automotive paint supply store should be able to scan it and match it up for you. If you feel you have the ability to use 3 part automotive paint and a spray gun. I'm in process of doing my '55 Johnson over now. My local major automotive supply place was able to scan my carb silencer and do a little custom mixing and got the sample they showed me pretty darn close to the original Sea Horse green. This is a first time undertaking for me, but I'm confident it will go well, or at least "close enough for a government job"

The primer is a self etching, made by SEM, about $22 a large can. The paint is an acrylic-enamel made by DuPont. In an email I just received from DuPont today I was advised to use a degreaser and powerwash the motor first, then use a cleaning agent before priming. I asked because I have some grease and oil spots on it from reassembling. All my parts have been sandblasted to the bare aluminum to start fresh, and to get rid of the olive drab the previous owner painted over the original green.

This method is certainly more expensive than spray cans, I think in the end I spent about 150 on paint supplies. It all depends on your budget and how much time you want to put into it. However, the primer is a "no sand" if topcoated within 24 hours, and the enamel doesn't require a clear coat. thus, no sanding in between.

The flip side to cans: I did a motorcycle over for a friend of mine about 15 years ago. Mind you, just a gas tank, fender, upper fairing, and some misc parts. I had to do a lot of wet sanding between coats. 2 primer, 2 color, and I think 2 or 3 clear of regular car paint cans from PepBoys. In the end, about $100 give or take.

I'm no expert, and I've never done this before. But that is the knowledge I have acquired thus far. If it works out for me, I'll post in a new thread after the weekend with some pics. Hope it helps you out.

This is the link for the "tips" page from nymarine. I think that those who have done much outboard painting will agree that his products are the better of those that are available. http://www.nymarine.ca/Tips.html

For general touch up, I found the Moeller products superior to the Tempo paints after they took over the Tempo line.

For most of the aerosol paints, a quality clear coat is needed.

I found the Moeller products superior to the Tempo paints after they took over the Tempo line.

...really?

I have 2 motors ruined my Moeller.
Not really ruined, but look like crap.

The primer doesn't stick to metal, and the paint doesn't stick to the primer.
The paint will fade after an hour in the sun.
Water will weaken the already week paint.
I used my outboard in the lake for !3 minutes! and the paint started coming off.
It'll scratch it you drop a rubber hose on it.
Gas will wash the stuff right off.

I was working on 2 engines at the same time, a 6hp, and a 20hp
No use in lake testing the 20hp, and it'll have to be disassembled and re-stripped again. Both will actually.

$200 in sandblasting, and $120 in paint they cost me.
+ time

ask a boat shop there true opinion on the stuff, most hate it too.
they just wont admit to it- they want you to buy some cans!

The stuff really does suck. Once I get everything worded properly, I'm writing them a letter.

Yes, your wording could improve.
