    It is very common to cut them flat.
    I have a new style, but I'm sure someone has a photo of the old style cut down... stay tuned...

    early and even later berk nozzles get cut down and modified in this area regularly , this will likely decrease the "efficiancy" of an already marginal reverse however Tom

    I was thinking it would help and be a little cheaper then buying a new one. On another note,"Impeller" I'm running a B-cut aggressor and turning 5600 RPM just advanced my cam to 6 degrees adv. on the crank trying to bring the curve down to the rpm range. 11.92 comp ratio 466 ford tunnel and 1050cfm carb. EST hp 600 the cam is a Schneider 306-14 R soiled roller. I built the engine to turn 7000 RPM but i think i have the wrong impeller and might be overloading the pump with the shoe and loader I'm running. The boat is a 77 Eliminator bubble deck with a delta bottom. Trying to brake the 80 mph mark. I was thinking of removing the loader to see what that would do. Thanks for the reply. I will try to post some pics of my set up.

    Are you refering to the prehistoric Berkeley steering nozzle like this? If so time to update, to a Place Diverer.

    if ya want to run a stock nozzle, IMO... cut it off flush just like a diverter.. or better yet order a diverter from jbp, they have a very fair price and you should pick up speed. and you can show off with your roost

    On that prehistoric nozzle, what is the indentation in the back for? The part below the outlet on the back of the reverse hook. Was this a spot to clip in a ski tow? or so you could attach a hose to use as a firehose? or what?

    The "V" shaped slot was actually for a drop in "break away" rudder The nozzle Chuck posted has been "modified" (for a later style Berk rudder)
    and yes Berkeley did have a fire hose attachment of some sort for the pumps (i'll dig for the pics) Tom

    Here are some pic's of the modified diverter cut flush. I was thinking of welding a plate on the bottom to make it like a newer diverter nozzle, But i don't think at WOT it drags in the water. I hope i have a little reverser left not much in the first place.

    if you drop it down you get more reverse power.
