Prop or more serious?
--------------------------------------------------------------------------------
Took the Earl out sat ,with yet another second hand outboard ,prop right jaggered up,so going at 6 odd knotts opened her up ,get acceleration,start to pick up, then horrid vibration,i throttled down,me thinks not just the prop,more like gears,oh dear what have i brought now?would the prop be the reason for this?can t believe its just a roughed up prop?no expert mind, just something not right?

Loverly sound ,started after a few pulls,get a good speed up with all the gear ,two of us as well ,smooth as,soon as i throttle up ,feel it pick up speed jolts forward,picks up speed then a rattled viabration,i throttled down,every time it done it, was worried i would do the gear box?few people have said ,it will be better when the props done, the prop is very jaggered,just hard to belive it has that much effect?

i would rule the prop out first i mean they turn quick if the balance is off i should imagine it would vibrate if its not the prop move on to the next suspect..daniel
