Very interested in the 525 cam in the 500 EFI results!
You Jet it down too?

He had a grounding/coil issue and ran with the old props, performs better than ever now, gained RPM and a few MPH from last years tired motors. Lou will have to give the specifics

I recently rebuilt my 500 EFIs with 525 cams, it was my 2nd rebuild (did it in 2012 stock), dynod in 2012, 520HP and 567 tq at 4000 rpm, now 2020 build with 525 cams 559.6 HP and 628 tq at 4000. Required an engine tune which still needs a little work in the boat but my 38 fever is running stronger for sure. With 28P bravos, ran new in 2002 83, (Reggie run it himself) and now 85!!
just an interesting mild upgrade experience I wanted to share..
