My 04 zx250 would only run 68 with 2, 72-73 solo with no poles

2017 pro xs 250 whats the rev limiter set at? thanks

How long does it take to flash it?

I have 3 of the 2 piece washers that are stretched out, one let the prop get into the lower unit, the sho has a ton of bottom end torque an they are going to have to come up with a better system,...

that 3.1 does not have the tq out of the hole as the sho, they will spin the merc just as fast, im having thrust washer problems, if your running the 2 piece you better check an see if its stretched,...

Not trim, motor height in general, need to lower your engine some

I put a new SHO on my 2004 skeeter an did not need anything, should all hook up coming from a yamaha.

The 4.2 200sho is the same motor as the 4.2 300 fourstroke, thats where they are getting the tune is from a 300 fourstroke an putting it into the ecu. my zx250 is rated for a 300hp so it should be...

Mine is flashed to a 300 an i did not change anything

Yamaha will not warranty it if they find its been flashed, how ever, buy the 200 break it in with ecu an put some hours on it, then buy a new ecu an have it flashed an if anything happens put your...

I bought a 200sho an flashed it to a 300 after my hpdi 250 blew up, best thing i ever did, think i gave 15,300 for the 200, 250 was 17,800 but was pointless to buy since i was flashing it.

Anyone know what is needed to hook a 2017 mercury 250xs to a 1040xs to be able to see data?

I hit a few things with it an it slowed down, its sent off to the prop shop to be fixed.

5850-5900 at 68-69 PTP 2 inch below, moved it to 2.3/4 below an ran about 69-70mph, water pressure 20-25, 12 inch slime master, almost empty fuel tank, light gear with two people, wells empty

I have a Bobs ordered just waiting on it to get here, i tried a 27t1 an it didnt runs as good at the fxp but the t1 wasnt worked, you think it would be much faster worked?

Went from a 26fxp to a 26sho prop an seems like it does not have enough lift, with 2 people it runs 68 with sho prop, 1 person about 74, with the fxp it would run 75-76 with 2 people, stood on the...

I figured it would be close to 80 as well but it is a heavy boat, I have a 27t1 an it didnt seem to run as well as my sho prop

Did you level the motor then start it for 5-6 sec shut it off wait 2 min then check it. they get an air bubble in them an have to be started after brought level..

I had 20 hours on the 2 piece an it failed letting prop contact my case.

WHERE DID YOU BUY IT FROM?

So im not sure how to take this, I ask you about the programming an you said to expect the same result as the simon tuning? so will it give me a noticeable power difference an pull to the limiter or...

HYDRO TEC WONT BE ANY DIFFERENT THEN SIMON. ITS JUST A COPY OF A 300 FOUR STROKE MAPPING.

WELL I TOOK MY MOTOR IN FOR A SERVICE AN THEY PULLED THE HOURS AN IT SHOWED 12K HOURS!!!! AN HAD 33 OVER REVS AN 25 OVER HEATS AN 30 LOW OIL PRESSURES, AN 3 CODES THAT MADE NO SENSE AT AT, THEY...
