I had bought a 1992 stoker that a engine problem since I picked it up.It would not accelerate after half throttle. I had been fighting this for a month.Testing this and testing that. The boat had a new CDI box installed on it when I picked it up. It would not run right. I followed some instructions off this site and ended up sending my injectors to Brucato and picked up one of his ACU's. Problem is now solved and boat runs great. Boat is a 20.4 stoker with a merc 2.5 260. I took it out yesterday and it fires right up,idles and makes power all through the powerband. Spun it up 3-4 times to 7600rpm and it was still pulling. Has a 24 pitch lightning et on it.Very very happy with the service from Brucato...Thanks Allen
