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 little top end, but now it’s gotten really bad.
I keep my boat in a freshwater slip. Last weekend I scrubbed the bottom of the hull & checked my zinc anodes, I also put in a set of NGK plugs. I can’t remember the spec, I think .028 was what they measured. The old plugs looked fine to me. I can’t see evidence of oil on the air filter.. I also ditched the 3x 12 lead batteries for 1x 36v lithium.
Nothing has brought my top speed back up.
Is 7k top RPM for the twin 1000cc in the FSH? I feel like hammer down vs 6000- 6500rpm makes a huge difference in the noise but only drops to 27mph versus hardly being able to hit 30-32.
Lake Erie.
569’ above sea level.
Very calm day.
Temperature mid 70’s.
Minimal equipment.
3/4 tank of fuel.
I’m planning on pulling the boat in the next week or two to do a bit of maintenance/cleaning. Not sure if I need to look closer at anything.
Thank you!
