So I did some searching tonight but I couldn't find any info i was looking for. I have seen several people say that the perfect pass system is a pretty easy install but i am wondering about the carburetor. How does it hook up?

same as the others has a servo that takes over operation of the throttle

what is the application mercruiser 4.3 <BR>we have done few and there are some mods to do <BR>and sent the info to PP cause they had no idea.

There are two kinds of PP. Mechanical which uses a servo motor for carbed boats. DBW or drive by wire is only for EFI boats. For a carbed boat you need a master module that doesn't say DBW and a servo motor. Other parts are the same (display, paddle wheel or gps, wiring harness). Good luck and PP people are very friendly call em up for a chat. <BR> <BR>(Message edited by wakemikey on February 23, 2010)

Easy install myself on 1996 Carb Mercruiser in Sanger. Best $$ I ever spent. Truely a marraige saver. No no reason to be pssied when I ride. They work awesome.
