I have a 2000 19ft Sea Pro DC with 2000 115 Johnson. Have a few dings on the prop. Is it more advisable to have it reconstructed or it is better to simply replaced (pretty small dings)? Along the same lines, should I be looking at a different style prop? The current one appears to be the standard 3 blade, I'm guessing 19pitch. What would be the benefits of changing the pitch? Also, is a 4 blade prop a consideration? Advantages/disadvantages? Thx, sd
