westerbeke overheating

[FloridaBoy]

I have a 1981 Westerbeke 50 serial #18p/830a/d426c005.
We have changed the heat exchanger,oil cooler,water pump,thermostat,and gauge also some of the hoses but we are still having overheating problems. I am new to posting on here I hope this is the right place and someone can point me in the right direction.

Sounds simple, but have you checked the thru hull for clogs?

What kind of over heat problems? Have you made sure the fresh water pump is working ? Have you checked for air in the system ? Is the exh manifold bad? Do you have a leaking head gasket? You can almost figure these out by the way it overheats.

Have you checked the water injection elbow?
This sample from an Yanmar engine shows the problem with flow restriction..
