Spray Painting Our Yanmar Engine

As some of you may already know, we hauled out our Yanmar 50Hp diesel engine in November 2016 to be serviced, cleaned and repainted. Oh my! It's a big B-I-G project! 

If you're thinking of doing the same, do check out our other posts related to this project or drop us a comment. We are by no means an expert on this, but now that we've done it, we'd be happy to share our thoughts and experiences if you have any specific questions or if you have some experiences of your own, we'd love to hear it.

Just be aware that it's a tedious and time consuming process (like everything else on a boat). It took us several weeks to get the engine parts ready for painting.

Check out our setup for Selwyn, the contractor we hired to spray paint the engine parts. We thought it was a smart idea to dangle the parts on the stands. But with only 2 stands, Alex and I had a good workout running back and forth ferrying the parts that day.

Once the parts were painted, we'd bring them back and hang them under the boat to dry
The next day, Alex and I decided to change the setup so that we could hang more than two items at a time. 2 A-frames, 2 pieces of long wood and a bunch of nails later...

Our new & improved setup
Voila! Much more efficient and a lot less running. We still had to walk the same amount carrying the parts back & forth, but it was a lot less hectic for us and a lot less waiting time for Selwyn.

"O" so beautiful
The spare fishing lines came in handy

Once all the parts were painted, Alex worked on the main engine block and ended up spray painting it himself.

All done! Not bad for a first timer hey
The time it took for us to complete the painting job? About 10 days (partly delayed due to weather). That excludes the many weeks of prep work i.e. cleaning off the old paint, taping off parts we did not want painted, stuffing screw holes with cloth, tying on fishing lines, etc, etc.

If you're interested to know what we used? Well, we applied 3 coats of Sea Hawk Tuff Stuff Premium Blister Protection High Build Epoxy Primer and 2 coats of OMNI M103 Top Coat Paint.
