14 Apache knows it all. He taught me everything I know. He is a freind of mine just joking.

Okay thanks folks. My internet been down for a couple days since I posted this so couldn't respond.
Sounds like could maybe gain a few mph since these two are so deep even though mounted flush in the front. Boat currently runs 74 with stock motors but only getting 18 degrees of timing(identical on both motors with no knock retard-but working on that issue also. I'll grind off 1/8" at a time and try it in a few weeks. Rebuilding a motor now.

How much pressure is in your can? LOL

I did some work on a 30 sutphen late this summer, the pickups were actually about an 1/8" above the bottom at the rear of the pickup. They were mounted just off center of the keel, water pressure was 10-12 lbs cruising, 15-18 wot.

Thanks Lil Red, It's good to hear that at least some boats can run the scoops ABOVE flush. I will grind off a little each trip in a month or so when I get the motor back in and try it. THis first try will be only from one half inch deep to 5/16" deep. Hopefully can go much further but don't want to screw em up. Each boat can be different.

Where is the proper location of water pressure readings?
Should it be on the thermostat housing below the thermostat, or down on the block?
Is there much of a pres difference between these two locations?.
