Lake irvine is all of 4 miles from my house. I'd love to check out my boat really close to home like that. I don't need to do 70 MPH, but what I do need to do is make sure my boat floats, the steering, reverser and diverter work, and the engine can idle without dieing. I assume the entire lake is a 10 MPH zone, and I even have mufflers in my transom. Anyone know if I drop my jet in there?
