mounting height with a skeg?

[JK3]

I'm mounting a 70hp Yamaha on a 17' semi-v hull (6.5 degree deadrise@transom). There is a skeg that runs from amidships all the way back to the transom that is approx. 1"W x 1.25"H high. Should I have the a/v plate even with the bottom of where the hull would be without the skeg or even with the bottom of the skeg? <br />Thanks

My vote: set it @ skeg height.

Don't agree. Set it at, or slightly above, the bottom at the top of the skeg.

JB, do you mean at the bottom where the V would be without the skeg? You don't think there will be an issue with water being displaced by the skeg? I do have the option of cutting back the skeg at a later date if I do have any problems, or it could be tapered to improve flow.

That's what I mean, JK3. The 1" wide skeg is not going to affect the prop. It will only diminish drag by the foot.<br /><br />If you put the AV plate down at the bottom of the skeg it will run under water on plane and create drag and handling problems.
