90 degree water is probably not your problem....how long since you changed out water pump?

Impeller, thermostats, and/or poppet valve. Likely one or a combination. Only other cause would be an obstruction in water flow somewhere.

Never had a problem with something like that. Hope you get it figured out.

if it only does it when you are idling around you have sand and small rocks in the poppet valve and need to clean it if it does it running on plane water pump or t-stats

On a 90 or 115 easy to replace yourself. On a 250 much more difficult if you don't have help. Sounds like water pump to me. Do you have a water pressure guage?

Anyone having problems overheating with 90 degree water What year and model engine? OX66? HPDI? Vmax? Had something similar happen to me after idling through a silted area, sucked a bunch of that into the water jacket and restricted the water flow.
