Hi,

I am replacing my prop as the old one is damaged. I have a 21dc with one aq170 engine and 270 drive. When I brought the old one to the shop, the owner told me that this prop was smaller than the original size when it was manufactured. The number on the prop indicates that it is a 15*16 but he believes the blades have been made smaller (may be as they were damaged). He has a cheap deal for me on prop size 15*15 and 15*17. He recommends me to go for the 17 version. However since I use the boat as well in the Amsterdam canals, I need a good low speed. I welcome any recommendations.

Hi Michiel.
I recomend you to go with the 15x17.
