Port: 225-AK3 418 hrs
Starb: 225-AK3: 851 hrs
Just did 400hr and 800hr services on these motors about 10 hrs ago. The 800hr service included valve adjustments, internal anodes, water-pump etc.
The starboard older engine has occasionally been a degree or two hotter than the port, but when running at cruising speeds (4500 rpm) - it often settles out to be shockingly identical (to the 1/10 of a degree). Today, I was running them at WOT for a while - maybe 10 minutes - and noticed the biggest temperature gap I have ever seen. Port was running at 210.2f and Starb was 221.0f. No overheat alarm.
A 10 degree difference seems troublesome, both motors were peeing strong and stream felt nice and cold.
My immediate thought goes to the work I did on the internal anodes on this motor as it was a painful extraction of vacuuming & dremmeling to get them out. Not sure if a tiny fragment of dislodged anode could cause an issue - I would have thought worst case it would block the pee-stream passages as those seem the smallest.
Anything else I should be thinking about?
