The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
To clarify, the AV plate wasn't 1.75 out of the water, it was 1.75 above the bottom of the transom or the bottom of the boat. Regardless, it was definitely too high.
I lowered it the last 2 holes so 1.5". Ventilation plate about .25" above the bottom of the boat now. I was able to hit 45mph...
See second paragraph, added Bay kit 5" spacer with drive shaft and shift shaft and water tube extensions to take it to a 25".
Presently the AV plate is about 1.75" above the bottom of the boat.
Ok, first some back story. New to me 2001 North River Mariner, 20ft, 2001 Mercury XR6 150hp, 20" long shaft on a 25" transom. XR6 came with a jet pump on it but also included the factory lower unit without a prop. XR6 mounted in hole 3 of 5 so I can go up or down another 1.5".
I hated steering...
