Friday I went fishing and evrything ran fine. After cleaning up i lifted the engine hatch for some reason and noticed that the coolant over flow bottles on both engines were above the full mark. And higher than normal. It looked like some had even flooded out the cap. Also the coolant was not the pinkish orange dexcool color but more brown. I did not have time to investigate further. Going back tomorrow. Any ideas what I am facing or what i should check? I fear a blown head gasket or othe really expensive repair. Only 750 hours on engines. 2006 Tiara 3000 Open.

Plan to check the pan for water in the oil and flush the cooling system. Dont know age of the risers off hand and have owned the boat for a year. I think they are 3 years old now maybe 4.
 
Discoloration usually indicates its time for new coolant....when was the last time the coolant was changed? has the coolant in the degas bottles remained at the FULL COLD level until this trip?
