I am currently running a 2008 ETEC 90 HP SL motor on my flats-Cat. I am having problems with overheating when the motor is at the higher settings on the JP. I am sure it is due to aeration in the water and not getting a consistent water flow. I have done some internet research and it appears as though I need to install high flow screens to assist in this problem. I am told by my Evinrude dealer that there are no high flow screens available for my model. I also see where others have installed screens that were made for the larger size Etec engines, and had no problems. Is this true? I am looking at the ultra high flow PN 5006337 or the high flow PN 5005063. Will these work?
What is the complete model number on your motor?
