I am building a jet boat. I would like to use a late model honda efi engine to power this small jet. Does anyone have an opinion on which engine might work well and who could build the harness and do the VATS delete to use the stock ecm and the boat chasis. I once put and efi Vortec engine in a jeep cj. I bought that harness at street and performance. i am unfamiliar with someone that does similar work on hondas
