Collection: ILMOR 5.3L GDI HO - 75 HOURS SERVICE

To maintain proper use of your Ilmor 5.3L GDI HO, and it's cooling temperature. Ilmor requires the impeller to be changed every 75 hours. Failure to due so can cause catastrophic engine failure. This should be done every 75 hours or 2 years. While under warranty it is a requirement annually. 

INSPECT
It is always a good idea to look over your boat. Checking gauges, voltage, and that everything works properly. No real inspection from Ilmor for this service interval. I normally just check Sea Strainer, Engine Alignment, and go through the boat to always make sure the boat doesn't need anything else.
