Mercruser carborator

[Rossco86]

Hi I had a flat spot on my 3.0 mercruser turn key. Just after idle the boat would struggle and sometimes stall. I was advised it was an carborator issue. I was able to remove it and put it in to a dealer for cleaning. I’ve now replaced it and the problem is much worse. The boat is constantly struggling to get fuel and is accelerating and decelerating at any speed except just ticking over.
I will be contacting the dealer again but in the mean time if there is anything yous can think of I might not be doing right or could try ?
Thanks, Ross.

Hi thanks I’ll double check that. I had the boat serviced end of last season so I’m assuming it was changed.
Thanks for the diagram. dose anyone have a link to a paper manual I could buy I’ve searched but unsure the best one to go for.
