[torchlake99]

Thanks folks,  my 3 blade props needed repair anyway from a ding last summer.  Decided to try the 4 blade and the dealer is going to repair the prop, no charge.  Will send info after boat gets into water this spring on the numbers.  I am not looking for more top end speed but more efficiency in the cruising range.  Will find out this year.  I do know technology in props has changed since the boat was constructed in 1999.  Will be a good experiment so compare the numbers vs the 3 blade this year.
