    210 fsh 30mph max speed @7000 rpm MY 2022

    Hi all, 2022 210 fsh I’ve owned it since new. Got the 10 hour service, just put new plugs in at 60ish hours. I have lost nearly 10mph off my top speed. I have seen 40+ mph, but now “hammer down” puts me at around 30-32mph (GPS on the fish finder). I noticed this spring that I had lost a...

    2017 FSH 190 Cranking RPM

    Could someone please confirm the correct cranking RPM for a 2017 1.8L HO engine in a 2017 FSH 190 jet boat? My current cranking RPM seems low, around 115-120 RPM. I was informed that it should be 300+ RPM for proper cranking. If possible, could someone check the cranking RPM on a similar setup...

    Just change the plugs!

    So, yea, long time no sea... work has been getting in the way of my personal life for way to long, and severely interfering in my water time. Even though, every time we have had a chance to get out on the boat (read... like four times a year) I have had no issues with the boat at all until last...

    Variable RPM

    I have a 2008, AR210 and one of the engines has periodic pulsing/changing rpm. It will run at 6500 an then suddenly jump to 7000 or 7500. The other one remains stable the entire time. Does anyone have an idea why or what would cause the RPM to jump like that. It seems if I move the throttle...
