    2021 Mercury Pro XS four stroke

    I have a 2004 TR21X had an optimax 225 on it. Just bought a 250 pro XS four stroke. Was running a trophy 26 on old motor. Anyone else put a four stroke on this boat I’m looking for prop information and suggestions. Thanks

    I've got a 2009 21hp pro and repowered with a 250 pro xs 4 stroke back in june. I've been running a 25 fury 3 and currently trying out a 24 fury 4.

    I have a 2004 tr21x and repowered with a new fourstroke 250. I run a 24 3 blade fury. 2 people loaded 77-78 right at 6000 rpms.By myself I have seen 79.1. Holeshot is amazing also.

    Anyone ever try a 4 blade? My boat loved the 25 trophy with the 2 stroke!

    Add 2degree wedge plate. Before I repowered my 20XS with a 4 stroke the Mercury service guys (travel crew) said ALL Triton hulls perform better with that wedge plate!
    for some reason that bigger motor seems to require the nose lifting with the wedge plate. I did and I like it!

    Repowered my 2010 21hp with a 300proxs 4s and though the Croxton worked 26p tempest + was the fastest the 25p fury 4 was only 2.5mph slower, very good holeshot and much better all around including very little chine. I also have a 24p fury 4 saved for summer and 3 guys that just jumps on plane but does give up another 2.5mph on the top end. Running 65mph with 3 guys is perfectly acceptable to me.
