When a bellows goes the water leaks into the bell housing and drips into the bilge ,but it is spun around the bell housing and ruins the starter motor and other related parts a bellows splits through lack of maintainance or lifting legs to high with engine in gear. Expensive !
Many years ago I had my name stamped on my spanner so .anywavy one day I went around a mates to borrow a spanner the size I didn't have so he lent me this spanner with my name stamped on it then argued it was his.
I'm sorry but I disagree my wife had 1 negative one followed by a positive one followed by another negative one ,resulted with colon cancer .caught early because of the test ,she waves operated on and is now all clear.
I had pagers and radio phons in my vehicles in the eighties but you could only speak for 2 minutes then the operator cut in and told you to finish your call cutting edge tech at the time.i used to come on the Broads with a pager.
It sounds like you are still relying on A sim card service, which can be hit and miss on the Broads regardless of whom your with but would be a good idea on the rivers and canals.
