Hi

I have a 28 Scarab Excel (1989) with 502 EFI, stock with Emi Thunder Exhaust /steel Riser. It is running 67 Mls at 5000 Rpm with a Swiss labfinished 21 Bravo Prop. I want to add a litle more Power with a XS EFI Upgrade Kit from Arizona Speed and Marine. It should make more tourqe so that the engine can turn a bigger prop and maybe reach 70 mls +.

Does anybody use this system ? what was the result ?
O r do you have a better way to add some Horses without open the Motor ?

Best Regards from Germany

Hans,
Tyler Crockett from Ruby, Michigan just installed an EFI upgrade kit on a 454MAG we have in a 25ft. Checkmate and it and a larger prop increased the speed by 7mph. Tyler installed the kit on our boat but will also send the parts and tune your ECU through mail.

Hi

Thanks for answering so fast.
What was in the package? Aircleaner, Adjustable Fuelpr. Ignitonbox MSD, and reprogramming ECU ? or something more ?
What was the price without labor.
I know Tailer Crocket from Hot Boat Magazin. I contact him before with a qustion for my 454/330. He make me a offer for some parts but the were so "overpriced" that i think he donīt want to make some buisnes to Germany. Or he was tired to answer questions from Hot Boat readers.
I go to the Miami Boatshow in Feb. 07. with my wife and some friends. I hoped to find a Firm from who i can buy such parts on the show (maybe with some organisation before). So i can save a lot of money for shipping, German custom an Tax (a few hundret Euro)

Thanks

Hans
