Guys, my 300 hpdi feels like sh*t out the hole. Once plane it runs fine but only spinning at 5400 rpm at 65 mph on a 25p t1 (stock). Feels like there's no power at all. VST filter, clear bowl (10 micron) filter, all plugs changed and still feels like no top end power. Throttle cable seems a bit stiff on hot foot. If jackplate (hydraulic) is raised all the way up during planing, it jumps out quick. Any ideas???
