Just purchased this boat during the off season. (already sunk $1000's into it) I have a problem with the Hurth Transmission Control Box leaking oil. Replacement prices are WAY too expensive. Does anyone have of or had experience with replacing or rebuilding these things. Its shoen in this diagram as part No. 20.

if it works well and just leaks why rebuild
just reseal...unless the leak is at the case split looks like 2 seals an an o-ring or two
