Thread: 300r vs 300xs on same boat

02-12-2020, 12:21 PM #136
And I love all the motors I have a 300X on my Finish built 24 Twister a 300XS on my 21 Young and did have 300Rs on my 28 DW . The XS is great on gas and does everything well. The 300X is nice and light and is a beast thanks Todd D but try shifting and idle around a dock with a 35 Dewald . I will take the 300Rs any day and they would shift and idle with 38s on them .Mercury has made some great Motors and has done a good job working with in the Regs. I am just glad to see improvement and not go backwards like the Muscle Cars did in late 60s and 70s.

02-12-2020, 04:41 PM #137will pull some fuel out and the cooler will b going out thursday morning with brent 2 c whats up still turning out and running a through da hub. I think the way it sits has a couple more .then will go 2 turning in and a better set of wheels over da hub.i kept running out of water press.trying 2 do 2 much on a new set up.im excited 2 c where it ends up when all is perfect.stay tuned
Going out 7.30 am got all the little things fixed will try 2 sets of wheels 15.25 x 35 5 bl through hubbers and 15.25 x 36 5bl hill props over hubbers will b testing with scawd the dawg brent.cant wait 2 c difference on top end from x.s 117.5 was best ever turning in . Know its faster in .but gonna try out tomorrow.IM A 2 STROKE LOVER 280.S ALL THE WAY HATED 300X.S DIDNT WORK 4 ME THESE R.S R JUST GREAT MOTORS<strike>
300xs Isn't that one of them 7 cylinder motors ... with a dead hole .. ?
By his own admission, he HATED the 7 cylinders .. how much effort would you put into something you hate .. ??? yeap, me either ..
<strike></strike>
In ~ Out ... I'll let you count .. yeap, looks like 1 set to me too ...
I'm not to put words in anyone's mouth, but I believe the 117 was with the 280's not the 7 cylinders.
However, my baseline was from a boat with 300x motors.
My question(s) still remain :
#1) how much faster should 1600 cc be worth ? (in this case 3200 cc )
#2) how much faster does $55,000 - $65,000 get ya ? (just curious)
#3) to be fair .. wouldn't a third 3.2L have to be installed ? Then the mid-range torque that makes it "feel" faster would be equal ...
Supa-star , said he loved the new motors .. and that's all that really matters in the end ...

Supa -Star are we talking about the same guy . He has yet to fix one of my Duke energy bills . Now on the other hand call Ryan I know he has way with those power poles some people call it climbing on top. I would love a 400 HP CRT motor on my Twister they look bad ass but how much coin are they. Cant wait to see them flying on a 32 Doug Wright now that will be hauling the mail.

Way cool video!
They claim 15% - 30% HP for properly designed pipes.
I put them on a 2 cyl 350cc that I raced in the day.
I raced that motor in a class w/o the pipes too (switched back n forth) and w/o the pipe it would turn 6K w/a test wheel.
First test, I was bummed when it only turned 6K w/the pipe???
That was w/it extended
W/it at 6K I pulled the pipe and it buried my 8K test tech!!
I'd rather be competitive w/junk I built in my garage than win w/stuff I bought.
I refuse to allow common sense to interfere w/my boat buying decisions.

MidLife .... That would be so hard to dock , but .. since I won't have to learn how to shift it , I'll take two .. BTW, hypoid is so expensive ... can I use 87 octane as lube
I tease enough, so I'll have to admit it's true ..
When them 3.0L's sneeze like a horse ..
Those POS 2 strokes need a shot of ether to get going again ...

Was a guy up here that used to build pipes for high altitude sleds, certain dealer would supply him with the new year model engine to use on a dyno to make them. He had a place he could test at 9000'. They did nothing at sea level but man did they work up high. I had 2 different sets on 2 different engines and they were amazing. the set I still have really liked it when I took a grinder to the ports. He quit doing it because Ski Doo kept changing engines and bodies of the sleds every year. People can't believe its a 700 and think its a big bore.
