Hi Pia & Carl. Very old experience from us: The function of the diesel engine in a pleasure boat takes up 90% of joy, annoyances, speculation and expenses. Your problem may be that you only have two boys who do not have training as (diesel) mechanics. So the chance of such a well-educated family member is, all else equal, greater if you have a daughter....! Chitchat. You will have a lovely summer this year in Heron in Greece. Hope to see you before you leave? Kh. Mette and Jan
