I have a evenrude tracker 40 that I just had the water pump, head gasket and thermostat replaced by a local guy but engine is still over heating. Any ideas?

Complete water pump kit ?-----Did he replace the seal at the outlet of the pump?-----Needs to be there since it does not have a water tube.----Overheating with boat in the lake?---On muffs ?----Or in a tub of water ?----Running with VRO in service ? ----Mixing oil at 50:1 in the tank ?

I bought a complete water pump kit for the guy to install. It's running on muffs.

Water that comes out the tell tale does not circulate through the block.------Could be an internal blockage.-----Any mud wasps in your area?
