Golden Eagles by Robert Mitchell, another one of his globe-trotting treasure hunt adventure thrillers, this one originally out from Australian publisher Boolarong Press in 1992.
Are the iron chests, chests filled with Golden Eagles – gold coins issued by the United States of America in the 1930’s and coveted the world over for their rarity – still on board the USS President Coolidge as she lies in her watery grave off the island of Espiritu Santo in Vanuatu? Or were they removed soon after she sank in October 1942?
Three people set sail from Townville, Australia, to seek those eagles out, to dive, to cut and force their way deep into the bowels of that once mighty passenger liner, but are they alone?
Their yacht, the Belle, is tracked to the island by others determined to hijack the coins, regardless of the cost.
The Coolidge lay quiet beneath the waves, and at peace.
But that peace would never again be the same.

Thunder Island by Larry Johns, an action adventure thriller (possibly crime-based according to the categories; it's hard to tell from the blurb which mainly consists of a cryptic excerpt from the book) originally out from UK publisher Robert Hale in 1980.
Greed, intrigue and triple-cross; the component parts of disaster. Gilby Nash, demolition expert extraordinary, reaches for a glittering prize on a sun-soaked island where the bullet and the knife are never far away.
Johns also offers a self-pub-looking mercenary adventure thriller, if you're interested.
