If your 29 is non stepped I think it would help. I spent a lot of time testing props and changing the drive height. At one point I had a 2" shorty with a 5 blade herring with the propshaft above the bottom of the boat. Cool rooster tail but no speed increase.

The steering is mounted to the transom. WPM made a wing plate to accommodate the box.

That's a cool pic. I can see everything but the lower unit. lol. Do you recomend raising the X dimention 2 inches from stock?

I opened up my side vents about 1 inch . the front vent and the rear vent. It helped by 1 MPH .wasn't getting enough clean air.

Sorry about that, here is a picture of the 2" shorty (when I ran it).

Is that how she was a@ 98? Looks like it could be a B1 30.

I have a labbed 28 B1. Getting 77 GPS@ 5400. I could use some more RPM. I thought I had low compression but it was the way I checked it was wrong . All cyls. are good. It feels like the prop is being drown under water. I think it is too low in the water.

Here is the cut outs.. Can't real even tell.. The way it is stock, I can't even slide my hand in the openiing. If you look at the newer ones, the vent is a lot bigger so I figured it would help and it did.

Thanks for posting.

Actually I sold the shorty and went back to the bravo lower with a hydro nose cone, where it is now. Yes, it is a b1 30.

Nice pictures, I modified mine too
