I hear you, i think they think i want something for nothing,thats not the case,thats why i'm trying to find out the solution before it gets launched this spring
I feel your pain, i also own the same boat with 220 hp cummings same vibration called marlow they wont disclose any info i do believe a 5 blade prop is the answer i am i the process of trying to find out what size when i find out i will post
Called marlow, they wouldn't give me any information, perhaps they think i want something for free not the case i do believe a five bladed prop may be the solution i just want to get it right the first time
Does anyone know the remody for the vibration i have at high rpms i understand this was a recall on early pilots prop clearance what was the fix thanks
