Sorry for so many questions, What rpms are you guys seeing on your 300hp? my boat did do 49pmh and sometimes 50 but i cant recall what rpms i was seeing at that. i know in the skis they do 8 to 8200. my boat now is doing 41 to 43 and turning 7500-7700 rpms. my boat does have 55hours on it and never had the wear ring changed so i will be doing that the next few days here. just looking for some more info!

thanks guys

I can't comment on the RPMs for the 300hp, hopefully someone else can along with top speed.

But does your wear ring need to be changed? This is something that only needs to be changed if it actually has wear on it (or the impeller of course). Tight clearance is important, but unless you see damage, deeper grooves, etc. You shouldn't have to change this. I'm at over 170h and on my original impeller and ring. Every thing is perfect still and running normal. I inspect it periodically, but that's it.

FYI, you can inspect the impeller and ring through the grate with a good flash light. You can also look at the other side by looking inside the jet nozzle with a flash light there too. In case you're taking it off just for that reason.

Unless you sucked up a sandbox or some rocks, your wear ring should be fine. A bad wear ring would result in cavitation, which is a slipping feeling on acceleration. A reduction in RPM is not likely related to this. You are pushing around more weight than a ski does, so max RPM may be less.

i understand you pushing more weight than a ski. im just hunting a problem of why i lost speed. In the jet ski world of seadoo i change wear rings ever 20 to 25 hours to keep it right. the lake that im on is not very deep.

I got about 47-48 mph on my 2019 195 300hp yesterday at around 7600-7700 rpm. That's about as fast as it's ever gone. I was solo and the boat's got about 35 hours to date.

as I posted in another thread, the Product Information Guide says that this boat should do around 44 at 7500 rpm and 48 at WOT (whatever that is).

My Sea-Doo rxt ski lost 2-300rpm from spring to summer with the heat and lost 5-6 mph on top .if the ring is wore I would think you would get higher rpms
