Fluxgate compass went funky around 3 AM and turned us 90 degrees. Desengage Pilot Track and switched to normal directional autohelm. Compass later corrected itself to match analog compass. Lightning all around. 430 AM winds steadily picked up, rising to 20 kts apparent. Then rainstorm, and winds died. All over in 20 minutes. Didn’t bother to take heady out. 9 AM shut off engine to add diesel. Put in two 27L jerry cans. Started her and within a few minutes temp went to 180 degrees F, 25 degrees above normal. Shut her off. Let her cool down to 150 deg F. Started again. Within a few minutes shoots to 240 deg F and alarm goes off. Shut down. Raw water was coming out exhaust, so fesh water likely problem. Let cool down while reading over engine books. Cools to 130 deg F. Check oil. 1/3 full. Add oil. Check coolant and see that overflow tank had spewed out coolant, which was in the bilge and overflow was full. Took off radiator cap and checked head and couldn’t see coolant. Added 1L coolant (premixed) and 0.3 L filter water until we could see coolant level. Siphone out overflow until slightly over “low” level. Started engine and watched closely for next few hours. Never over 160 deg F. Motored rest of the way. Jumped in and snorkeled to tiny outcrop off anchorage; poor visibility but good coral and fish. Fishermen cambe by and we bought 3 fish (1 kilo) for 40k Rupiah. De-scaled, gutted, and filleted two of them and cooked in ghee, salt, pepper and lime. Pretty good. Need to work on filet cutting skills. Big cell phone tower on next island = 5 bars of EDGE.
