Thanks Phil! The motor is mounted second hole from the top (1 hole above the mounting bold). I understand the motor should be mounted one more hole up (2 holes above the bolt). The dealer was uncomfortable installing it in that position, I can’t remember why, but we compromised on the current setup. I realize I’m leaving some MPH on the table.

No T-top or Bimini top. An old bottom paint job. I keep the boat trailered so I haven’t repainted it. Just me on the boat (180#). Two batteries installed in the center console. About 15 gal of gas. Maybe 50# of gear (cooler, anchor, life jackets, equip bag). I was running into a stiff wind on somewhat chop with the new SS prop. I’ll have to run it on smooth water…but that shouldn’t drop the RPMs by 800 right? Only thing changed between the old prop and the new prop was getting the 20hr service complete.

Thanks Phil T!
