blew a coolant hose yesterday, caught the temp rising just as it hit 180. Shut the motor off and was towed in by an excellent Capt Lee and Tim from Tow Boat US Beaufort, NC. Replaced the hose but was reflecting on the possibilities from overheat (although minimal) and my gut told me to check the oil. Really? Dipstick read almost 4" above the full mark. Checked the gear level to ensure I didn't blow a seal under tow but gear level was perfect. Drained the oil and got 4+ gal of other than oil fluids in the beginning of the drain.
Suggestions where I go from here to determine where the intrusion occured
