Can you describe the proper way to adjust the throttle cables? Is it done at the throttle handles or at the throttle body?

Does the Throttle Position Sensor do ANYTHING? You would think that it would compensate for differences between the two engines, but I guess not...

How about any information regarding adjustment of the jet nozzles? It seems like my boat pulls to the starboard side above 5,500 rpms....

I took the boat out on Sunday - very light chop, slight wind....

I managed to register a 57.3 reading with GPS; Speedo registered 42 mph, BTW.

This was with just me driving, 1/3 tank of gas. Bimini top was down but still on boat; I wonder if I could get another couple MPH out of it if I took the bimini all the way off?!?!?!?!?

Still showing about a 400 rpm difference between stbd and port engines...

I think it's an oil change / filter change / coolant change / general TLC to each engine. At least that's what the 10-hour service was that I had done last week. $159 for both engines.

this weekend i went out and found a couple of things i have questions about, and do thank you guys ahead of time for the help. First problem i would start up and notice the speedometer wasn't on. weird so i kept on to the next stop, and after the next start up bothe the rpm guages were not working so i killed the engines again and fired it back up no problem. just wondering if anyone had experienced this before and had any suggestions.

the last thing was when cruising around between 5000 and 6000 rpm i would get swome serious rocking (cavatation) going on, and this had not happened on previous outings at same speed and conditions? any help, thanks again.

The cavitation issue is common to the pumps on the new skis and boats. www.sea-doo.net has information on this if you search the board. It seems these pumps are VERY sensitive to the smallest foreign object in the pump. 1/4" pieces of debris have been known to cause cavitation and a terrible vibration.

The usual remedy is to shut off the engine and drift - the piece usually dislodges itself. Next time it happens to me, I'm going to try putting the boat in reverse and then shutting the engines off so water will drift backwards through the pump.

I've had this problem on both my 2005 Speedster 200 and my 2004 GTX SC. I've never had this problem with my '98 Speedster or my '98 GTX Ltd.

The gauge problem is weird. On my first 15 minutes with my boat, the tachs locked on 5500 rpm and wouldn't move until I shut off the engine and re-started. They've been fine ever since.

If the speedo's not working, your paddle might be stuck under the rear transom. If that thing's not spinning, your speedo won't work.

Hope this helps,

Craig
