Both, idle and full throttle.
Just bought the motor so I don't know when the last time the impeller was replaced. Telltale pee is very strong.
Compression on all four cylinders is 110.
Can someone please tell me what the proper heat range should be when read from an infrared gun? I have a Johnson 115 1998 bubbleback. It seems to be a little hot when I put my hand on the heads.
Thanks
