Yeah, I'm with ya, the older Westerbekes just ran till they were worn out. You could troubleshoot and replace just the component that needed replacing. Now it seems as if we have a generation of parts changers. Just keep replacing stuff till it starts working. Temps are so much more critical now with the electronic stuff, particularly the boards. Makes me glad I'm retired. I used to be a plumber also and we would rebuild valves from the 1930s, they were more like artwork especially the tub/shower valves, then cartridges came in and people just started throwing stuff away. Such a shame that we don't fix stuff like we used to. Just replaced a leaking cork seal on my 1951 Lincoln glass fuel pump bowl and it was easy, try that with any newer car. Of course there are trade offs, my Lincoln has a 337 cubic inch engine that is lucky to squeeze out 150 hp. Sorry, I'm getting on a tangent.
