Now that winter is upon us and lots of people are contimplating winter mods to thier boats. I have been wondering why after market engines have to cost 25k to 35 for a 600hp EFI engine. I know builders need to make money but when someone says they have 30k into a 600hp engine it makes me say hmmmm. Is there nobody that makes a decent 600hp engine for under 20k? I would love to hear others thought on the matter. I called Pfaff today and was quoted 30k for the 600efi not installed without tax:jawdrop:
