700 Mis range crap out
Lil help anyone. 06 700 sci left side engine was running perfect all last season and has never given me any issues. Had some minor over heat issues with right side got those fixed boat sat for about a month and a half. Started boat at dock for first test run for season left engine started but just did not seem 100% thought maybe carbo or a rusty plug. Started run boat planed out ran out ok seem to have about 20% power loss on left side. Retuned to dock left engine stalled out was crapping out at mid range. Got back to shop ran on hose no codes found, check fuel pressure and water separator all good, Pulled plugs all looked good, checked map sensor, Nothing on Di Com and no codes stored in ECM. There Is an alarm at about 3500 rpms but nothing showing up on gauges or the on board system. Anyone else had this issue? Any help?? Thanks
