Cold starts ok on choke and throttle lever up, idles around 1000 when lever down,no stalling when gear engaged.Starts easy again without throttle if motor turned off after warm up. No problem apparent when high speed running on water for say 7 miles but gets hard to start again after stopping motor . The small throttle lever has to be hard up to get it to start again.It can take 3 - 4 or more turn overs before start. When throttle put back down and the revs reduced to go into gear the outboard stalls out. I have to try and get into gear before the revs lower by quickly dropping the lever and engaging gear fast. I may stall out perhaps three or more times before getting under way! Any thoughts much appreciated on this almost new Merc?
