RE: SK 90-----WOW
Hi Ernie,
Yes, I checked the opening in the back is about 5 times the inlet. I really do not think the outlet is a problem at this time. I had an OS-61 in this model before and it was working fine. No problems with overheating.
Thanks for the input though.
Due to bad weather, I was not able to test the proposed changes today. The weather forecast says it will be clear skies by Wednesday. I shall see then.
Thanks to everyone providing their knowledge and sharing their experiences.
Pedro
