I rebuilt my first Marinette (a 26') in 1999 and installed all Marelon, including a 1 1/2" seacock for the engine pickup (raw water cooled). That seacock was removed last year and it is like new. As you noted, no electrical issues at all. The larger seacock is very robust and never left me in doubt, but I am on fresh water, Lake Michigan.
My current rebuild is an M32. I am using all Marelon for thru-hulls, as well as (2) 1 1/2" seacocks for engine pickups, (1) 3/4" seacock for a/c intake, and (2) 1 1/2" valves for each of the sink drains.
In short, I believe in them.
I don't remember where I read it, it might be in their instructions....but as part of winter lay-up each year I pull the hose and pour 4-5 drops of cooking oil on the ball, open/close the handle a couple times...it's good for another year.
Hope that helps.

Re: Marelon Seacocks and Below the Waterline Through Hulls
I used all Marelon... thru-hulls, sea scoop, and seacock. Worked like a charm...
A note of caution re: bronze on an aluminum hull. Previous owner of my current M used (1) bronze thru hull for the a/c unit. As a result, pitting of the hull radiates from that thru hull, along the keel line. Stray current caused the pitting, which would not have happened had the thru-hull been Marelon.

Re: Marelon Seacocks and Below the Waterline Through Hulls
My only question about Marelon, Is it impact resistant? Can it handle a direct hit from say a log while on plane? That is the only thing that I have worried about.

Marelon has been around a long time and is proven product in the marine industry.
