Anyone see the new Merc Pro XS v-8 engines?

[Walkabout7781]

Friend told me a *Ranger official* went to Merc's Lake X and ran one...said it was bad...azzzz

I didn't think *Johnny Morris* talked like that...

My 175 SHO is "making oil" 3 years after purchase. Dealer put regular oil, instead of synthetic, on my last oil change to see if I can get it to stop. I run the dog mess out of this thing and still cant get it stop.

In many four strokes they have a cross hatch pattern in the cylinder walls that helps the rings wear in. If you don’t get a good break in, the cross hatch is worn off without the rings seating fully. But, I have no idea if that’s how your motor was built.

The go fast guys never took to the HPDI for the most part...Lots of Opti’s on go fast boats.

Yes, but it’s been said a few times that this motor is faster. Now wether that’s true or not...

[Iowabass3826]

Probably gonna make oil like crazy too

kind of an outlandish claim on a product that has seen no run time on the market

I like it....just wonder how much it will devalue my 2 stroke Pro XS?

Just sold a 16 for 13,800 rigged with 77 hrs. They'll hold their value for sure. As someone said, a lot of guys love their Optimax's

I like the looks of them.....bet they sound awesome

[Gthunter5]

Only thing I don’t like about my SHO is where it’s made

hope these are great engines and my next boat will have one

Interesting, with a V8 only making 250ish HP. Sounds like lots of potential for more power from in the future. Wouldn't be surprised to see someone like Simmons or maybe even HydroTec get some big HP out of the engine.

Hey as long as they can make them not fail Id be happy.

They are advertised as V-6's, not V-8's.

250 and 300 are v8

guesing the 250 is detuned

[twofin]

Lol. Thanks for that.

[TritonJT]

The Pro XS's are V8's. The regular ones are V6's.

The mid looks like a 300x motor..

Beautiful rig and motor.i'd run it and not give a rip what anyone says.

Yes,me too! Like when auto makers change styling,I have to let it grow on me a bit. If I can except the looks of an E-rude,it will grow on me. Main thing is it's reliability and power!

The Fusion/Plasma sprayed on cylinders are in a lot of engines. Some motorcycles, some automotive and from i'm told they are in some big diesels as well. IMO the big problem is you can't run an outboard above (approximately) 140 degrees. All others are running in access of 200-220 degrees. The outboards are using lake, river, sea water with all the minerals and contaminants in it. The water evaporates out at the higher temps causing the minerals and such to be left in the water jackets in the block.
Water cooled with closed loop, i.e. radiators or heat exchangers can help this. But on a water to water heat exchanger the fresh water side still has issues. They will loose heat transfer and completely stop up after a period to time with calcium and such. All this said, break in is tough in some cases but it can be done.

Then that makes the praise for the product just as outlandish
