I am looking for the part number for the aft adapter that fits the Mercury Flo-Torq hub 835258 K2 or Quicksilver Flo-Torq hub 835258 Q2. Just for information sake,, the K1 or Q1 aft adapter part number is 826074 K1 or Q1 and there is a difference in the length. K1 or Q1 is longer than the K2 or Q2.
K1 or Q1 hub fits the old style Mercruiser Bravo 1 props. K2 or Q2 hub fits the newer style Mercury Marine Bravo 1 props.

We would love to help you and answer your question.
I'm a little confused by the way the question was asked. No disrespect intended.
Hub kits get a little confusing. I remember trying to get the part numbers straight while doing the catalog updates at Mercury. We never had things totally correct and we are still making adjustments to the old part number sequence today.
Could you please give me a call and I'm sure we'll be able to get to the bottom of all your questions.

Brett
