I am new to this site. I have recently had issues with engine idle rpm' slowing down and stalling on a cold start. I get the engine to start easily (per cold start instructions). It warms up under a faster idle around 1100/1200 rpm and then idles down to around 700 without any problems. Within a minute or so, it then starts to loose rpm, run rough, and stall. Restart and same results. Try to rev in neutral to keep going but it is running rough until underway and shortly after runs fine for hours. This problem just began as I have owned this boat for 3 years without this issue. Any thoughts?
