I have a 05 speedster 200 SC and recently I have experienced situations where the tach particuarly the port freezes while running at whatever rpm it was before I changed the throttle position. Also I have seen the tachs peg past the 8000 rpm mark. If you stop the engines and restart they seem to work right or sometimes you can move the throttles back and forth and they will read right. The engines are running fine the whole time. Any info appreciated.

Thanks

I have an 06 S200 and mine do it also. If you look on Jetboating.net this subject has been posted plenty of times and everybody has experienced it. I don't believe anyone has found a cure. Just have to live with it for now I guess. Hope this helps.

Yep, me too.
It happened twice on the same ride. The first time, I was just cruising along planing and then slowed down to idle speed. I looked down at the tachs and they were both frozen at 5500 RPM. I increased speed above and below this level a couple times and nothing changed. After about a minute, they both kicked in again and worked fine. A little later on, they both stuck at idle speed for a short time and then came to life again.
As you said, the engines were running normally the whole time.
It has not happened to me again yet, so I haven't even bothered talking to my dealer about it. I didn't realize this was a common occurance.
Let me know if you find out a cause or solution.
Thanks,
Curt

mine did the same for a couple of trips and now it doesnt work at all - just an initial flicker when you attach the dess key - hopefully the dealer will fill at end of season service.

Update on tach problems, last weekend at an idle the starboard engine tack would fluctuate between 2000-3500 rpm at an idle. Engine speed was normal. This is the first time I have seen this occur. Usually it is at higher speed and they freeze or read way high.

Mine do the freeze thing from time to time and a couple of weeks ago my port tach was reading about 1000 RPM high for two days then it went back to normal. It sounds like they have a couple of different problems in the same circuit. When reading high the Port tach would show more than 8K (way more) on my 310HP '05, I could tell the engines were both turning at the same speed and were normal (7200-7300 RPM for me).

My '03 Sportster 4 tec norm asperated Tach frooze up many times and finaly ended up to pointing straight down upon spring startup. Cleaned contacts, no luck, checked incomming sig. it was good. Checked ground, it was good. Gave the tach a couple of raps with a 3/8" socket 6" extention, needle cam unlodged. Plugged it and it was slow to respond to ignition pulse test when ign. turned on would go to 5k and stick. I unpluged it and ( tach was already taken loose from dash ) put a spary staw on a can of CRC and removed the light from the tach. I then sprayed CRC inside the tach. Then pluged it in and powered it, tach went from 0 to 5500, powered it again and it did a little better, kept on powering on and off a dozen times and it moved freely from 0 to 8k no problems, it now responds correctly when in use. Only - was I do have a little CRC visable inside the lense but only a drop or two and CRC will not hurt plastic!!!
