I have one of these outriggers but it is not Derale and not very good quality. The casting seems fine and the threads are well done, but the problem is the filter gasket finish, it's terrible, the finish has never been finished, it has numerous pits and ridges. I thought I'd show up right away, but why do I have to pay for this item while others are working on it? I will return it if it's the best Taiwan can do then they shouldn't do it for me.
