Yeah, I did mine "in house" with a bunch of help from friends as well as some colorful choice words along the way. At the end of it all, best thing I ever did to the old boat. It used to take full throttle to get the boat up out of the hole and on plane, now it doesn't even require the secondaries to open up. My trailer tire to fender clearance gained an inch or more in space between the fenders and the tire.
