Downeast newbie here... I was on their website and their 34 ' price was about 55k hull , top and couple add ons. So here is the question. What kind of power would u need/ fit? Cummins 25 kt cruise or minimal power. Cost effective . And how much for installation and power on that. Motor shaft etc. Would that include deck?? And finish over time chairs , electronics , head , etc when I can afford it. I wanna get an idea on price but I don't bother them w alot of dumb questions..ANY and ALL info is appreciated
