Benbrook boat test

I think this is a 1 in a million, but I did some repairs on my pontoon boat outboard, and want to test it at Benbrook. If I do, and something goes wrong, I will have no secondary motor to get me back. Was hoping someone might be going out that way anyway that I could call... I plan to run it 10 or 15 minutes and see what it does. then return to the launch. Seems to be ok under the muffs, but muffs and lake are sometimes two different things... text me if you will out that way between 730 and 830 - 817-689-7842 i am 15 minutes from the lake, if not may try tomorrow.
