Re: 1999 Merc 115
I have a 96 on my ProCraft, works great, on I dialed it in.
Follow the factory directions for the link and synch, make sure the accelerator pump is exactly set by the book. The 2 + 2 system idles on the top 2 cyl's, the moment the throttle is moved open the accelerator gives a shot to bring in the bottom 2 cyl's and it wakes right up, no problems other than I don't use it often enough that fuel starts to degrade. Be religious about adding stabilizer with EVERY fueling just in case you don't use it soon enough.
I run NGK BPR8HS-10 spark plugs and change them annually, they are a LOT cheaper than the BPZ's and I haven't been able to detect any difference in performance.
So I'm a cheap SOB. I'm cost effective.
