I would love to. However, last week I spoke with Merc. Racing folks and they said to run Merc. 25w40 non-syn. So that's what I'm running. Teague says no problem to run synthetic in his mag. articles though. I would also like to know if any are running synthetic. The new syn. Mercruiser motor oil is NOT for Merc. Racing motors. The Mercury Racing branch is different from Mercruiser or Mercury.

Mobile 15-50 in 575SCi's with 430 hours.
Just did a valve job due to leakdown (tired valves).
I could still see the crosshatching on the cylinder
walls.
