Just noticed something in your last pics. Does the starboard prop have some damage to the blades? If so this could be a piece of the issue.

Mercruiser spends a lot of time researching ways for parts to fail. They have to, otherwise they wouldn't be so good at it.

For some reason it's too much out of those props and they are sucking air from above. Walking the throttle slowly allows the water to continue to be "feeding" the prop as the boat moves faster. I'd be very surprised if you put a 5 blade on if you had any issue getting on plane. Not a 26 pitch, probably a 24. If this is a problem that has been "slowly" getting worse you might have water intrusion somewhere. We have cut a lot of boats apart and sometimes find vast amounts of soaking wet foam and even standing water in sealed compartments. My old Sonic ran 68 @ 5000 with 26 Bravo ones. Labbed props do not plane out as well in all my experiences.

Bencini,

OP hasn’t posted any pics of his props yet. He’s mentioned he is using brand new props, though.

Thanks. Brad.
