Anyone disappointed with the new XS 250 4 stroke?

[ChooChooSnakeMan]

The newer merc lower units have alot less slip than the old ones. This allows for a smaller pitch prop to achieve the same speed at the same rpm as a bigger prop with more slip. Also allows for better holeshot with a smaller pitch, and as stated, a 6200 rpm max on the merc. The fury prop that most are running also is a bit stiff, a 24 is more like a 25 etc

Thanks for the explanation, I can see how prop slip plays into the equation, good explanation in simple terms!

I will add that most are trying run to large of pitch and are not getting to the recommended RPM for that motor. Also running them to high and excessive trim.

Bought my Merc 250 in 2019, and have 300 hours on her....best motor I have ever owned, and I have owned a few over 60 years. On this big Delta, takes 24 maps to cover it, it is never a 20 minute run....you will put hours on an engine.

And then add to that the quad bracket to accommodate 2@ 12" graphs, 2@ 15" graphs, an Ultrex, and at least one point-GPS system hanging on the bow.

Now that we're looking for contact lenses on the bottom of the lake... we'll switch from AGM's to Lithiums (times 3 or 4), and make the handiest lockers the ones under the front deck.

Ok... I'm picking fun, but I swear, I've seen ^^^^ that boat more times than I can count!

Ive driven several boats with 250 pro XS and 250 SHO. The Yamaha really shines in midrange instant punch imo. Both have great hole shot. pro XS probably can get a little higher top end.
My next engine will be a 300R. Merc got the 300R right!

I went from a stock 250 SHO and my best was 67 mph ONCE, but consistently 65 mph yes mid range was great but motor kind of fell on it's face from 5200-5900 rpms. To a 300 R and consistently 79 mph. Tons of power throughout the rpm band.

Not sure how a 300r compares to a 250xs. Thoughts?

Good info. Thank you

I repowered my 2002 520vx with a new proXS 250 four stroke just a month ago and this hull loves it. Rated for 225 but is 20’9” and not much weight difference in motors. Running a 23 pitch tempest plus with a great hole shot and midrange acceleration to match. I’ve not seen top end yet but have hit 72 with not much trim. I have 15 hours on it now. I’m almost glad my old optimax blew up. Lol

Oh man, the HP police are going to be coming. Some guys on here are convinced you'll run into a schoolbus full of children if you run over the hull rating.

Bring it….

Got another few hours on it and did the "wot for up to 5 minutes" a few times. Only saw 6k rpm with 67.1mph. Need to figure out the sweet spot for the bobs and motor. Tournament weight
