Fixing an overheated engine on a remote tropical island

The great thing (one of the many) about travelling on your own boat is that you can get access to the least visited and most remote areas of this glorious blue planet. The Anambas archipelago, in the South China Sea between Borneo and mainland Malaysia, is one of those places.

We came here in 2017 (some of you may remember) and we’re thrilled to be going back again on our eastbound trip towards Japan. We wonder how much it has changed?

At Pedang Malang beach on Jemaja, one of our all-time favourite anchorages, we dropped the hook. It’s not necessarily the most remote island in the group (the airport is now finished since we were last there) but it’s still beautiful and bathes the visitor in a warm local welcome.

The two mile white beach stretches towards uninterrupted views of distant rain forests. Hills shimmer on the horizon. There are no hotels or resorts here.

Are you a regular viewer? Do you enjoy our work?  FTBMates is our private members club, for one-on-one chats with us. And to maybe pick up a gift or two:

  • T-shirts and Hoodies
  • Mugs and Dog-tags,
  • Hats and Bags
  • Early-bird access to FTB episodes
  • VIP content
  • Exclusive videos.
  • And YOU could be sailing with us aboard SY Esper!

We stayed for days, enjoying the snorkelling and taking the oldest scooters in the world through the island’s interior. We were reluctant to leave because we needed to check in at Tarempa, the capital of these islands. Eventually, as we waved goodbye, we weighed anchor in 6m of water on firm sand.

But Esper’s engine temperature began to soar almost immediately, so we turned it off and re-anchored, sharpish. Now what?

What would you do in this situation?

Let us know your thoughts in the comments!

Thanks for joining our adventure.

Peace and fair winds

  1. Well first thing is say F-ck it, have a beer let the mptor cool down then start from intake if the motor is seawater cooled or the heat exchanger if fresh water cooled. Well depending on the condition of the impeller.
    The iron sail a blessing and a curse all at the same time.

  2. Hi. The 1st time we left Majuro for Mexico we turned around just outside the pass with Perkins 4-236 overheat. Flushed fresh water system. Removed heat exchanger, cleaned it out physically and chemically with vinegar.. Deposits restricting entrance to exhaust cooler and elbow water injection to exhaust were cleaned out. Raw water pump checked. After all that Apolima was good to go. Next time we left we got as far as Wake Island when autopilot quit and hydraulic steering failed. Luckily she was equipped with a sturdy emergency tiller, that we dubbed “Rusty” which got us back to Majuro. Try again next year.
