Thanks, Which prop is 18 x 21.5 Port or starboard?You should verify, but you probably have 4 blade 18 x 21 and 18 x 21.5 props on 1.5” shafts. That’s what may 2004 340 with 8.1S Horizon engines came with.

RJ is correct for 2006 and 2008 8.1 Horizon engines! But not all 2004 models.I couldn't remember which is which so I pulled the following from my per-purchase survey.
Port: 18 x 21.5 LH
Stbd: 18 x 21 RH
Glad you posted this. Definitely a difference between 2004 and 2006. I will ammend my earlier response.Here is a link to the Searay Propeller chart for 2004 models.

I am interested in your props. I need to purchase a second set, as the Potomac basin has twice reached up and grabbed me. Thanks, MacI have a set for sale
