2008 Mercruiser 8.1l misfire/knocking. Seems to get worst as engine heats up. It’s coming from the port side of the starboard engine. If I hold my hand on the exhaust I can feel it. Last time out didn’t notice any loss of power but didn’t go over 3K rpm. I only heard it after changing oil and running engine with hatch open. So far replaced plugs, checked plug wires and coils on that side of engine. The injectors and cool fuel module were replaced about six months ago.
Any suggestions before I get someone out with a computer. I’m told the code will at least get me started in the right direction.
Thanks
