I've got a 99 Lavey 24 NuEra. It has a 454 Mag MPI with Imco exhaust in it. (See photo in the March 99 Hot Boat, Stern Drive Tech section) After reading the answer by Tyler Crockett, the general consensus from everyone is that he wants to sell me one of his engines. I have since also ruled out a supercharger after having a serious reality check talk with our mechanic at Quality performance Marine.
They recomend installing the Vortech Maxflow EFI Power Pack for a boost in performance without sacrificing reliability and warranties. Has anyone installed one of these packages? What type of results did you get from it?
