I added a set of dart heads and a small cam to my slow 245 limited this winter,I finally got it out this weekend,I expected a little more but I guess I am happy with the results,last season it was only doing 46 on gps with a 19P prop,I got a best so far of a solid 50 on gps with full tank of fuel,I guess it is not bad for a single small block boat,I will for sure go with a 30 ft with twin BB on my next boat.
I tried the 21P prop and planing was horrible,I guess 19 is where it stays.
