thanks for your info hope you get it dialed in

We need more info on the final MPH @ RPM

Nothing more for ya guys. Sorry to say this is my last weekend out and lots of rain in the forecast. I am too busy this fall and no way the boat will get used so I plan to winterize soon. I will say that I am very happy over all in that I have had no drive issues. Secondly I have the 1400 lower that has the extended skeg that goes almost to the tip of the nose cone. Imco explained to me that they did this design to help settle the stern as too many people complained of too much stern lift likely due to the bigger cone area. Even w 5 blades I have not felt my stern getting too much lift.

Thanks Pete,

I'm just tring to see how your compares to mine. Not sure if i need to raise my drive height.

If the centerline of the bullet is even with the bottom of the hull, it's just going to push the drive upwards.

They should have given it a flat head in profile so that it's lift neutral at any X. Sort of like this. Forgive the paint drawing, I can't shade well on there. I think this what merc did with its new drive, but I haven't seen a good photo of it.

I am trying to under stand the physics of what your describing. wont it have equal up and downward forces? or are you saying that there will be less water running overtop of the bullet than under due to drive height? Mine is 2.5 in below the bottom of the boat and on boxes

If part of the upper half of your bullet is above the bottom of your hull, then it is creating some lift. Also due to the upper part of the lower begin present, the drive would likely create some lift even if it's plunged deep in the water.
