Hi everyone just looking for any advice before I bring her into get looked at. I have a '96, or '97 (can't remember) Mercury Blackmax that has been converted from oil injected to mix 50:1. Every time I run her over 3/4 throttle for more than about 5 minutes, when I bring it back to neutral (even close to idle sometimes) she stalls. I've always had some trouble after I've been out for awhile in the lower rpm's stallingafter long rides but now it happens every time. I thought maybe it was over heating but the water seems to be spitting out fine so I don't think its the impeller. I also always thought it ran to low ( rpm wise) in neutral before the problem as well. I always had to start it at about 1/4 throttle. Any suggestions on what could be wrong? Any help would be appreciated. Thanks in adavance.
