Our 78 Gulfstar 44 has twin Perkins 6.354Ts. A few years ago the port thermostat went bad. Engine specs call for it to run at 180, could only reach 120. The replacement we were finally able to locate was much smaller than the old one and required a "spacer". With that in place it worked perfectly. Recently the starboard began to demonstrate the same difficulty, running at just 120. Our other supplier having gone out of business we contacted first one, then a second authorized Perkins dealer. The first sent us a thermostat that is far too large for the installation. The second sent us one that is far too small. This after taking all our specs including even the engine number. This is a 1978 Perkins 6.354T but it seems even Perkins experts can't get us the right replacement thermostat. Any one have any suggestions short of replacing the engines?
