Thought I'd start a new thread on this, rather than hijack Marian Clare's thread...
All this talk of flow and heat exchange reminded me - when I brought my boat back to her slip last weekend, I noticed that the temp never got much above 150 on the gauge. Now I never ran her hard, but I would have thought that even just running along at around 1200-1400 RPM would have made the engine get up to full operating temp. So if that is the case, then it would seem that "full operating temp" in this case was only 150.
I'm thinking I'm going to need to play around with the bypass valve to see what effect it has when I slightly open or slightly close it.
What about slightly hotter plugs? The engine was a little hard to start, to my surprise. I am using the plugs that were in it when I took it out, because they seemed to be fine. But I could easily decided to yank them out and put new ones in.
I also don't know if maybe I need to to a little tinkering with the carb. I kinda don't want to.
