2007 SX 210 RPMs

[PCatoe]

Okay guys I’ve searched with very little luck. I have a 2007 SX 210. Port motor turns about 82-8400 RPMs. Stbd motor 7500 best. I’ve done a full service on it so new plugs and filter/s oil all that. And I’ve inspected impellers and wear rings both look normal and identical. Looks like previous owner installed stainless wear rings. So I am lost. Is it even a big deal. And both throttles are going to the stops as well. Boat runs 37-39 mph with 2 adults and 2 kids which seems normal when I match rpms by throttling port motor I run about 34-35. Sorry for the long post and thanks in advance for the help!!!

Thank you I guess because I was searching specific for 2007 I never came across this thread!! Makes sense!

I only knew about it because I had the same issue!

You can reliably tell by sound if the starboard is turning slow by backing down the port throttle and listening for the sync droning as they truly match up. Your speed is a bit slow as I see 40-43 WOT very consistently regardless of fuel/pax load (unless you pack with 9 adults). It may take longer to get to max speed but it usually ends up the same place. Wind and waves mostly account for the small variance.
