etec 50hp

[ben_460]

hi all,

I have a 50hp etec which gets a slight miss from 5000rpm to flat out- 5800ish depending on load. I have only noticed it in glassy smooth water when you can feel it through the boat but not really hear it. Has anyone had similar issues?

I recently had a sevice, new plugs and one injector replaced but made no difference.

Ben,
I just got my boat back from Logan River Marine where they replace the throttle sensor and re-mapped the engine. I too had a slight miss and they think it will help the problem..albeit a small problem..the miss in mine occured in the 3000-4000 range but only slight...other than that excellent motor..the guys at LRM were really good too very friendly and helpful

Its a stacer sunmaster runabout with a 13 7/8x15 prop. I've recently bought it 2nd hand so am still not used to how it should run. The book tells me WOT will be 5500-6000 on the 50etec.
It's not a real drama just sorting out any bugs while it is still under warranty. Otherwise seems like a great motor.
