The boat’s 30ft LWL 25ft with 4000kg displacement. Maximum prop size is 13 in. Hull speed is about 7kts maximum. One engineer says I need to replace the old Watermota 33hp petrol engine with a minimum 28hp diesel. The other avers that a 16hp diesel will be right. Quite a gap in size and price! Cost is of course an issue, but so’s safety. Here’s the dilemma. Would anyone care to make observations?
