Dear Gents,
I have Wellcraft Martinique 29 with single Volvo Penta KAD 42-B
When cruising between 1500 RPM - 2500 RPM at around 7 knots - 14 knots, there is no any overheat problem.
However, when at full throttle around 3000 - 3500 RPM, engine starts to heat and then overheat and alarms rings.
After getting the boat Neutral, heating goes down to its normal within 30 seconds or 1 minutes time.
How an overheated engine can go to its normal heat within 30 seconds ?
What sould the problem be ?
Thx
