You have mis-matched threads and should not have straight (what your thru-hull is) to tapered threads (which is probably what your valve is). Some earlier Marelon valves were also a straight thread which is what the thru-hull is and that will most likely never make a seal.
Furthermore bronze and Marelon should not be used together due to differing expansion / contraction characteristics. This is especially true of a male thru-hull into a female Marelon valve..
