Diverter Nozzle Adjustment

« **on:** September 22, 2007, 10:50:15 AM »

I am wondering, is there any good reason that the diveter nozzle should have any down thrust? If so, for what purpose?

Thanks,
Greg

Keeps the nose of the boat down.

If I'm understanding the question correctly, pointing the diverter nozzle down helps by pointing the boat's nose down while running over wakes, making the ride a lot smoother.

It will also help your reverse around the dock since the reverse passage way is at a better angle .

So, just how much down angle should I have? The way it's set up now, adjustment wise, I don't think there is any down and maybe a 2* up at the lowest trim handle lock. Max up movement is only 1" on the Jetovator tube. I should be able to get something better than that, shouldn't I? Thanks, Greg

BJ, I just might be able to do that in a few minutes.

Here we go:

Jetovator Full Down:

Jetovator Full Up:

Actual Movement:

I'd also like to add more up angle without replacing the entire unit. Any suggestions? I do see some small modifications that Squirtcha did to his, but I don't really want to cut into the bowl nozzle.

The way I see it . The berk nozzle already has a good reverse passage way for reverse . Thats probably why the nozzle doesnt go down too far .

Up seems to look fine to me . Thats my .02

BJ, Any suggestions as to how I might get more UP nozzle for a better rooster tail?? Other than replacing everything and putting a Place Diverter on it?

Beerjet has the best roost I have ever seen. Change the pump to a split bowl, add a droop with 4 degrees up and a couple of wedges. You too will be hosin down the bridge at the Avi. I dont think just changing to a place diverter will do all that much more. Just my $.02

Thanks for the advice but I'm trying to keep this Miller as original as I can. I don't need to hose down a bridge just get a little more height. Also, been told that I do need some down angle. I don't think the photos show how little, if any down angle there is.

To me it looks like there is no down because the nozzle has the reverse passage way built in . If rivertard ever gets a new computer you can see how he did his . The only way your gonna get more altitude is to cut on it or grind some of it off . The C-bowl just doesnt give you anymore adjustment . If your not lookin to get too crazy with it , it might be the way to go . You'll be surprised how much more roost you get with a little cutting . $:-\$

So BJ, you don't think I need to worry about any more down angle?

« **Reply #14 on:** September 23, 2007, 01:20:27 AM »

I dont think so . Those nozzles with the passageway facing back the way they do , do a pretty good job of forcing water backwards . I didnt design it though . Thats just my logic on the subject .

Cool, I'll just add a small amount of up then. Thanks!

Did some tweaking today, will upload new pics after while.

Here we go - AFTER TWEAKING!

Jetovator Full Down:

Jetovator Full Up:

Actual Movement:
BEFORE:

AFTER:

Did a lot of cable adjusting and took off a little of the nozzle to even out what had already been done. I know, I've got to replace the broken rudder too.

Greg looks like you got it dicked to me ,good job on the adjustment !! Tom

« **Reply #19 on:** September 23, 2007, 08:30:36 PM »

Looks much better, still have about the same up angle but more downward travel. Good work!

Thanks Reb. I can get more up if I need to. It just means file out some more aluminum.

I would like to use all my pump and jetovator only find a hydraulic or electric means of moving the nozzle. That darn manual trim handle really sucks and is hard to work when all connected up. Everything is a very smooth operation until connected. I can't find the bind area though.

Looks good Greg. You gained quite a bit of angle there. Good job

Thanks John. Now if I could only figure out why the trim control get's so hard to operate. Everything is loose and smooth until it's all hooked together and then that trim controller (the one you use up by your feet) gets very hard to operate. Over the winter I think I'll pull the pump apart and rebuild it.

Hey Tom, got any suggestions??

Greg

Greg the biggest issues weve seen with that setup relate to the steer tube where it passes thru the transom adaptor (binding etc) . I could see where the leverage factor could probaly be increased slightly at the jet also what controller do you have? Tom
