yeah, it's still got the flange. So I didn't mention it in the original post, but I leave the boat sit in the water so that doesn't help. Didn't say that because even if it's clean the above issues are all true. Anyways it's been in the water for about 2 weeks now (bottom was clean before put in) so it's got some growth on the bottom.

Tried taking it out today, could not get it on plane the entire time. Tried all the tips I was given in here, nothing could get it on plane. Tried leaving the throttles at 2500 and 3500rpm for probably over a minute each, wouldn't plane. Also tried aggressively talking off too, which never works. Tried every combo with tabs up or down, drives in or further out. Gave up, and had to idle the boat back in. I don't know what do. Going to try a local place that works on performance boats I've heard about in Monroe, Mi to see if he sees anything wrong.

Did you ever get the pictures of the drives like I asked earlier ? If the spacer is in front of the pin( like a bravo 3 uses ) the drive doesn’t trim down as far as it normally should

Sounds like it could be a prop issue? Have you tried larger diameter props?

no, sorry. The boat is still in the water, I'm probably going to pull it out today or tomorrow.

I've not tried a larger prop. The props that came with it from factory were 26p 4 blade Bravo props. The ones that came with it have been labbed, and the prop blades are very sharp and thin. So I bought a new set to see if it would be better. It is slightly better, but not by much. New props are 400rpms off from eachother, so I took them off until I get them to a prop shop to modify them.

I'm trying to figure out what spacer to make sure in the picture you can see it once I pull it out. Found a picture online and circled the spacer I think your talking about, let me know if that's what you're trying to check out. Thanks.

#30 is the spacer, it should be towards the transom

Is this an exploded view of a B-1?? When did they start having an oval where #30 fits? Mine B-1's are not oval. No spacer or shim.

I believe around 97’ they made the change, the spacer is white, plastic and resembles a celery stick

Maybe you should record a video from the drivers seat. Maybe someone else from the shore could also take a vid? You will have to post to youtube and provide the link.

Is it possible the hubs are spinning?

I don't think so, I've swapped props a couple times and the hub looks good. Nothing scratched up.
