I will add yesterday it would only pull 4400 rpm and it skipped like crap. today it pulled 5000 and ran like a champ. Of course I know the engine should not run this fast, it's just the prop.

It runs fantastic under power and it idles great, just that stupid smoke

I can’t wait to hear how it runs after you swap in those new injectors.

I hope it runs fine. My concern is I just dont see how one cylinder could be causing that much smoke.

I'm testing the injectors tomorrow for leaks or dripping. I'm also testing the water temp unit that goes to the computer. Number 6 cylinder had a bad wire and fouled plug.

This engine has always laughed at me when I've tried to figure out issues with it. I don't understand the GT40 engine, wish I had a LS engine in it. Nothing is ever easy with this boat
