changed the SC washers and now I lost some PRM's
05 RXP with 44 hrs bone stock.
I just sent the SC to Jerry and had the washers changed to the metal ones to prevent any issues. Before I sent it off the ski would hit 8100-8150rpms.... now after the washers have been changed it only reaches 7700-7750 rpms.
I can't tell if I lost any speed cause it feels like it pulls pretty good. It runs great, but just doesn't get the rpms like before.
nothing else changed.... any idea what may be causing this? Is there a break in period for the new washers?
Oil level is fine (check when the engine was warm and ski was level)
water conditions/ temp didn't changed
thanks in advance

Make sure your hoses are seated correctly and take a driver to every clamp.

Mine dropped too. I could not find any boost leaks for the life of me.
My ski was a 68mph one bone stock with 10 hours on it. It how has 40 hours and only goes 65mph max. I turn 7700 rpm now.
I hear your pain. No one could help me either other than check prop, wear ring, oil level, boost leak.

ok, just took the hose off to check for a boost leak.... odd thing is inside the hose going from the SC to the TB there is a slight film of motor oil...Is this normal? do I have a seal issue pulling oil from the crankcase into the TB from the SC? could this be causing my RPM loss?
Also note: there weren't anysigns any boost leak the clamps where tight and seated correctly. I will double check them to make sure when I reinstall them in a bit.
a reply asap would be great, as I am out on the water as I type this.

proper oil check proceedure:
With a hot engine let it idle 30 seconds
Shut it off and wait 30 seconds
Check your oil. You want it mid way between the two bends on the stick.
