Prop advice

Now that we are done with Abby... I have a very old prop (50 years?). It is two blade folding with no gears or anything fancy. I think it is a Martek. I attached a very poor picture of it. I like it a lot but I have this vibration and my diver said I should get it "tuned up", whatever that is. The bearing is relatively new (1 year old) and the diver said it was good. My typical engine use is motoring 1 mile to get out of the channel and another mile to return to the slip. There are times when I need to motor as much as 5 miles and these happen a couple of times a year. I don't trust my 55 year old engine for longer than that so it is unlikely I would need to motor greater distances. It would be nice to get rid of the vibration but perhaps the most cost effective thing is to ignore it. I would appreciate some advice. Allen

next off season send it to Martec for inspedtion. if necessary they will rebuild/rebalance it.
