Opinions on cold water break in?
Hoping to break in Oldman's FZR this weekend as we have some 70 degree weather coming our way, but Bob mentioned a concern he had. Is there any evidence or reasoning to support that breaking in an open loop 4-stroke in 45 degree water can hinder seating of the rings and hamper performance in the long run. I think on a stock factory motor everything should be okay as long as you allow a proper warmup.
What are the opinions from those with experience?

Open loop with a thermostat. Doesn't that scream problems. Seems like the perfect place for salt, sand, debris to build up and prevent it from opening. Am I missing something or just over thinking this?

My old 84 inline 4 mercruiser had open loop cooling and a t-stat, this is nothing new. dumps the water through the pipe, then when it needs more cooling opens the t-stat and dumps the hot water and replenishes with cool simple system.

my 94 polaris had a thermostat too nothing new in marine applications. And with emissions, fuel injection and forced induction, having a handle on engine temp is even more critical.
