Should make a little over 700HP. I had a Vortech on my 500efi. Running low boost (5 pounds). Got over 300 hours of trouble free use out of it. Made the boat come to life. 26' American Offshore.

About 725 hp. You will be very happy with it. Make sure that the fuel system in the boat is up to par. You need to be sure that there is no anti-siphon valve, the pickup is large enough, and the fuel hoses and water seperator are sufficient. Give me a shout if I can help in any way.
