this is now the second season with no answers yet. My port motor gets up to 3.9 at half throttle and same with starboard motor. When I give more throttle starboard motor goes up over 5.5 rpm giving outstanding power and port motor gives nothing more. After a while it will increase slightly as it’s working off the other motor it seems. Things I’ve done so far. Checked timing by a professional, replaced fuel pump. Checked all cylinders doing a compression test and fantastic compression. She throttles up in neutral no problem it’s when it’s under way. Would anyone have any idea what it could be the restriction? I’ve even took off props and sent them out to be checked and cleaned and tuned up, could it be a fuel restriction? Any help from anyone that had this in the past would be sincerely appreciated. I’m racking my brain. Thanks
