kmoose, I have the AP.
I have mentioned to the installer the info that I have received from other Seacraft owners with the same boat and motor. Before they raise the motor they want to try a 4 blade. They measured the distance from the bottom of the haul to the bottom of the AV plate which is one inch. Which is where they say it should be.

I appreciate your input.

Thanks

My 23 CC was installed with a 20.5"Suzuki prop. Lightly loaded I hit 5850rpm's and 51mph. MPG is unreal at 27mph like 3.60-3.7. My issue was offshore in rough weather at 20mph she was trying to stay on plane at 2900 rpm's and wallowed a bit.

I switched to a 18.5" factory watergrip prop. RPM's came up to 6000. Speed dropped to 49.5mph. I have a bimini top, radar arch and Garmin radar. I also have a bracket which I believe adds 2mph. Now my offshore performance is 3300 rpm's at about 20mph and overall better low end performance and I have bottom paint.

Do not try a 4 blade. Raise that bitch THREE holes!

Seacraft hulls need the AV plate high to get clear of the water. BEFORE you go playing around with props, just look over the transom while you are at cruise - if the AV plate is not clear then raise it. Repeat until it is clear. The 23 likes 2-3inches. I have talked with guys running them as much as 3.5 up without a bracket. The 'right' prop with the drive buried is probably not the right prop with the drive in the right place. A buried drive will cost you fuel and speed.

You have a 25” notched transom, correct? I have the same motor (250/300ap 25”), same transom mount. Don’t mess with the props until you get the height correct. It is a waste of your time. As I said 3 weeks ago, raise the motor - all the way up. How many 23 Sceptres has your guy dialed in?? If your guy knows what he is doing, then he just doesn’t want to make the effort. My concern is that he doesn’t know what he is doing. You’ve got 6 people who know what they are talking about telling you to raise the motor. I had to do the same thing with my Suzuki 300AP and just like Flexpat told you tonight, I am also up at least 3 - 3.5 inches above the keel. Don’t let your guy keep leading you down the wrong path, tell him what you want, it’s your time and trouble. Do it. Good luck.

Sounds like they don't want to take the time to raise the motor. The AP motors have low water pick up for a reason. It would take them 15 minutes to do it, put an 18.5 on it and call it a day. I don't understand why the dealer is being so reluctant but you are being very patient with him.
