Hi Scott,
I have never primed it or had to prime it. The generator was installed new in 2004 when I bought the boat (also new). I don't have the model # here. ( The boat is about an hour and a half away.) The gas is relatively new and both the VolvoPenta engine and the Kohler generator run off the same gas tank (I have no problem starting the VolvoPenta). Thanks, Bruce
