temp diff on warm up

[scoflaw]

New issue this year, not sure what to make of it. 1 engine will warm up quicker than other with about a 15 degree dif and then they settle down at around 160. Closed cooled. Any thoughts? Thanks Mike

as long as niether engine is overheating i wouldn't worry about it

when was the last time you replaced sea water pumps?? check coolers/strainers for weeds/debris?? check coolant levels??
