Hi Jason, glad to see your on this forum as well. Here are some tips for your U47 - Pushrod bellows should be fine as they are (Engel do them that way), but are more leak free if you mount them on the inside on the bulkhead rather than out in a Positive pressure WTC (increase pressure will just collaspse the bellow rather than blowing through it). Rather than using oil tubes to waterproof your prop shafts, fit a Simmerring sealing ring to the end of the tubes in the WTC (or a Subtech type seal).
