Outboard jet positioning question

[slider]

Is there a rule of thumb as to where the leading edge of a jet intake should be in relation to the bottom of the boat? Even? Slightly higher? Slightly lower?

Thank you.

From what I've heard it should be slightly higher, but it depends how smooth your boat bottom is. Hold a straightedge to the bottom, this should hit about where the pin goes through that holds the front of the grate bars. That should get you pretty close.

Thank you sir. Someone had told me that it should sit a half inch lower and that didn't seem right. Seems like it would drag a bit. It's a riveted 1648 with strakes... nothing out of the ordinary.

Start with the bottom of the intake flush.

If you search these forums or outboardjets.com you will find a TON of info..
