Can the rear engine have issues with rain?

Your question is rather general so not much to go on with what might be the problem. I can give a general answer about water, however. In my many years of ownership, water is what I fear the most when it comes to wreaking havoc on our airplanes. It gets everywhere and it will cause problems. In my mind, it’s a HUGE safety issue. I would not own an airplane if it had to live outside. I know not everyone can afford or even gain availability to a hangar, but at a minimum, you’re going to work a lot harder fighting to keep water, hot and cold cycles, snow, wind, hail, critters, and maybe even vandals from harming your aircraft. Please don’t get me wrong, I’m not saying not to do it, I’m just saying be prepared for problems or you hopefully can figure out how to protect the aircraft even though it’s outside. For me personally, the effort required to mitigate these issues outside is more than I’d be willing take on. That’s just me though. If it’s possible, try to get it inside.
