I'm guessing because they don't know it happened or don't want to believe it did happen. I do know the 400R wants a prop with a lot more blade area than the 2-stroke, and probably larger diameter, too, because of the larger gearcase.

Just wanted to post a message to say that I made my trip out to Mercury Racing and it was awesome. The people at Mercury Racing are absolutely fantastic. The service they did for me of setting up my boat was priceless. They are at the top in their field for sure. It would have taken me a whole season to do what they accomplished in three days. The props they built for me really let my boat get to its top limits. The set up is perfect and I don’t think there is anything left on the table. All that and also had a ton of fun at it too. Once again, Thank you all. All the hard work all of you did is greatly appreciated. Stephen V. Lane III.

I'm glad Mercury knows how to set them up...
I wonder how much those five blade prototype CNC props are $$$

when you have a open checkbook one can accomplish anything,

A buddy of mine has 30 Motion with twin 300XS's that hops horribly. I drove it once and it was nothing like my Spectre. Are Motions known for that?

**2jz** · 11-30-2015, 08:29 AM

Im no expert but this guy said his motion did 102mph with mercury 300s. So in his head and everyone else mind that's thinking about 400r my current setup did X mph with this setup if i add 200hp with same prop i should go faster, but ur mph falls back i would be wtf. I think size of gear case and correct prop is a big challenge that most don't want to deal with or expected. A friend of mine seen prop on gear case and he said it's like a 1" opening around prop how big gear case is.
To date he said he ran 97mph and needing more prop

maybe he does not have enough grease in the case.

Short answer is no they are not known for that. I have owned two of them and I have a friend of mine that owns another one and none of them have/had a bad hop. All depends on setup.

I rebuilt a pair of 280's on a 30 motion, boat went 107, running 3 blade cleavers, it hopped from 50 or so into the 70s

Maybe he should have got the 400 Yamaha's....oh they dont have one? Happy Holidays Greg

I dont mean to be controversial but for the kinda money for a twin setup of those 400R,s cost you could easily have more HP and 30+ mph faster for WAAAAY cheeper and still have reliability. DBR 450-500 hp OMC comes to mind just as one example. Pluss the added advantage of half the weight let alone half the cost!! HP cost money but i think Merc is out of touch with whats really already available with these motors. they are nothing more than glorified fishing motors it would seem for 30-50ft cruisers. Not one high performance boat has seen any gains over what has been available for over 10 years from what i can see? If your going to call an out board 400R it better be faster than a 250 fishing motor on the same boat. im pretty sure twin 250xs fishing motors would do 94 on a 30ft motoin also and have less porpoise. There twice as much money as they should be it seems to be for there performance. if they cant make an out board 400hp the is under 500lbs they shouldn't even bother. This motor is going to go down in history as the biggest failed attempt to scam the market out of there pocket books Merc has ever built. Thats ok because some of the new 450hp 400lb 8000++ rpm motors are hear now so why spend 10+ grand more for nothing more than a boat anchor? When i see a twin setup do over 140mph Ill change my mind for there uses but i havent heard of that yet. I have heard of 140+mph from a single 300 two stroke though. Im not one for going backward.

**eli** · 11-30-2015, 04:27 PM

for some reason when 4 chokes came out to replace 2 strokes I always looked at the performance loss when tested on bass boats
a 20 fishing rig with a 200 merc vs a 200 4 choke would be 3 to 5 mph less speed may better bottom end and way more weight
we all know an engine with intake and exhaust valves can make horsepower look at the motor cycles four stroke and 10,000 rpm
200 mph so why cannot 4 choke outboards do the same gosh you would think a 300 4 stroke would perform same as a 300 2 stroke
a 300 x @6800 rpm vs a 300 4 choke @ 6800 rpm should put out same power you would think ,I remember my 1978 Suzuki 750 dohc is was a screamer 8500 rpm 140 mph 12 sec quarter mile et went thru 2 rear tires 1 summer blow away any 2 stroke my point is can be done 30 years later .

How much is 2 400R Verados vs a 700/1100 Mercruiser ? (1720 lbs)

**whipper** · 11-30-2015, 04:59 PM

Yes good points. The KX450F spins to 8500+rpm 4 stroke. its only now in the past 2 years been able to beat a 250 KX two stroke from 10+ years ago. The whole 4 stroke thing is all about profit not so much performance. The 400r is probably the biggest example of this i have ever seen. for instance the XCat motors do not even resemble the 30000 dollar motor you or i can buy. those motors are highly modified and are closer to $60000 motors each setup for racing. my point is the 400R off the shelf Im pretty sure is targeting the 40ft Fishing croud that are looking to go 50-60 mph max. Theres no way the off the shelf motor has any business on an actual high performance boat. that 30ft motion is a great example of more money than brains. If my boat did 112 with a pair of 2000 300promax engines and just dropped 80 grand+ on a pair of 400r motors with rigging it better do over 125 or im going to loose it.

then you go back and say I can only get my boat to 94 or 100 well oh your going to need some of these extras like two new gearcases and these two $3000+ props but you will never see more than 110 even after that?? what a joke.... Tell ya what ill just strap on twin 300xs motors i found for 10 grand each and add 15 inch mids and full DBR mods and for under half the cost gain more than the 400r will ever be capable of no matter what cost. Im sure the 400R works good to 50mph on a 40+ footer in twin and tripple setups off the self. Im pretty sure thats the only target target for these motors anyway buy the sounds of it. or if your happy with only getting 100-110 out of your new 30ft skater with 100 grand worth of out board hanging of the back more power to ya. More a fishing motor unless you spend another 50 large per motor like the XCat motors. then you might get the same performance as the old 300,s or 280,s will give you for 10 grand. haha Maybe in 10 more years Merc will hire someone old enough that understands power to weight. In the mean time they will have to play catch up now because true outboard company's will be way ahead of them by then. They are making decent car motors for boats these days though. Ill give them that.

BTW my buddy's new bullet car motor makes over 800hp and weighs only 500 lbs for his jetboat. haha Pretty sure the busa v8 outbard that revs to 10000 rpm and has over 500 hp cost less than the 400R and will run to 1000+ hours.
