Here at Boost Lab we also service Marine Injectors. Here is a set we did for a customer who brought us Mercruiser 454/502 805225A1 Injectors.

After:
All injectors were flow matched to within 1% except Injector number 5 which is being replaced as it suffered salt water damage.
If you are a boat shop looking to get a closer source for injector flowing/cleaning give us a call - (813) 443-0531. If you are anywhere in Florida we can sometimes get your injectors back to you within 48 hours of you shipping.
