Are you having a issue keeping temperature in the engine? What is the temperature when it warms up?

@@mikemoreno7329 kind of….. I wanna go closed cooling so I’m not paying a ton of attention to it. But. It ran 190 with a 180 Tstat. I drilled a bleed hole in the Tstat because it was boiling the water. It’s now running 150-160 which the LS isn’t happy about but it’s getting it done. We took it out today and let it eat, and it kept cool the whole time.

@@dieseltechjb enclosed cooling system is the way to go. I’m in the process of doing the same but just worried about keeping temperature in the engine. Thanks for your quick reply.

​@mikemoreno7329 closed is better no doubt. But for open I ended up plumbing mine so that it goes into the exhaust first to preheat, then into the engine the back out to the last 2 water ports on the risers to exit. Works really well. Boat sits at 175 with a 164 Stat.
