I have a 5.0 Volvo with EFI. The damn boat backfires when running at full throttle. It also has little to no hull shot was trying I am trying to wake board. My boat is a 19' Chaparral 1999. Any suggestions?
No...this is the right place...
Heres what you should look at...
1. Timming
2. Mechanical advance
3. Too lean
4. Burnt and/or out of adjustment valve
Good luck.
