ah, great to hear! presume you would rate your rpm ranges as normal, not lots of hours above 4500 or 5000? As for the header work, Shogren in Chicago (now Pier 57) did it per the Merc recall for the original owner. I am the 2nd owner. Beautiful work. I will drain all blue plugs. Thx!

[QUOTE=On Time;4238207]My story is rare on this forum. Very little WOT time, probably 3-4%. Most cruising at 4200-4500. We used to go faster but my "governor" kicked in after my kids were born..... Oil change every 20-25 hrs only Merc 24W-40 oil dino until they came out with the semi syn now thats what I use. Fresh water use only. Original headers with ?

Recent pressure test with winterizing was 100%.

Yes boat only sees Conroe, and Travis when it has water. My mechanic is Clear Lake Powerboat Service. The Marlago has outboards and only sees salt water.
