So let me start by saying i got stuck out in the kelp beds and overheated this motor causing the cylinder head to break. i have since replaced the head and i have resolved that issue which was allowing water to mix into the motor oil. Now im having a issue of the outboard overheating after only 30 minutes of run time I've even gotten it to happen while at high idle on the dock. I've just taken apart the lower unit looking for some kind of indicator of why this might b happening however i cant seem to find any. The pair of gaskets on the water pump are stuck on the metal plate however if it was that then there would have been water in the lower unit oil. Im stuck and have no idea what could be causing this and any tips on where i should go from here would be great.
The outboard is a 2017 25hp 4stoke Mercury
has brand new impeller
brand new head and base gasket
new cylinder head
no water in either of the oils
