route for lake machias(seven dollar bay? to the mrgo?

im trying to fish the islands that are south of seven dollar bay area this saturday. i would like to finish up inside the mrgo. i have a 17 foot boat so i cant handle to much open water in my routes. it looks like there is a cut on the south end of seven dollar bay and to the east of that inside the bay a bayou empties into it that will connect me to spoil canal. has anyone ever navigated this area and knows if this is a safe route? i have never been in seven dollar bay before but have heard its shallow. on google earth the route looks good. thanks for any help. trying to add a picture.

are both routes safe? thanks

i navigate that area pretty frequently and both of the starred canals in the first picture are deep enough to navigate through. However, beware of the canal that exits 7 dollar at its southwest it can be quite shallow.
