2018 Merc standard 4-stroke vs Merc Pro XS 4-stroke

[CRosh324]

What are the pro's and con's of the standard Merc 4-stroke vs the Merc Pro XS 4-stroke?  a friend of mine is selling his 2018 Nitro Z-18.  It has a 2018 standard Merc 4-stroke, 150 HP.  Just wondering about this motor compared to the Pro XS 4-strokes?

I'm not sure but I think someone knowledgeable will be along to answer this.

I haven't torn these motors down but have been told that the Pro XS has carbon fiber reeds versus traditional, extra hardened pistons and is electrically tweaked to give a faster hole shot and maybe a little more top end.

Are you missing out if you go with just a 4 stroke versus a Pro XS four stroke. I wouldn't think so.

I talked to my mechanic and he says that if you take the cowlings off and run them apples to apples you can't tell the difference.

that helps a lot!  Thanks for the information!

You will be crazy happy with the standard motor.

Mike, something clicked in my puny brain after checking this topic out, so I just re-read what you wrote. Reeds. REEDS?!?

Mike your talking about Optis not 4S. The Proxs Optis had Carbonfiber Reeds and were tweeked a bit for a better hole shot. Top end is or was supposed to be the same or within 1-2 MPH.

The 4S looked to be a different Motor to me. The Original Ones had a bigger Cowl and different look. I think where they went Full On 4-Stroke they re-designed everything. The New Ones are sweet motors.

There are also 3 different lower options depending on the HP.  The 250 ProXS typically comes with a Tourqe Master but can come with the other two.

A 150 probably only has one option.
