With ballast tanks full, and PnP full, in surf mode port or starboard, cavitation plate seems to make no difference, the wave sucks.

Just acquired a 650 front bag, but haven’t run it yet

I have the same boat and the wave is great.
I have a 650 bow sac, try bleed off the non- surf side for about 15-30 seconds, you'll see the wave get much better. Run about 11.2 mph. Use the cavity plate to clean it up.
Try this pin location and adjust the secondary fin straight out no angle.
Hope this helps.

Move your pins like MKLs and flatten the second “flap” to almost completely flat.

Plate position is the problem.

Got it, I'll adjust them while I'm in there cutting out that weed/rope I somehow wrapped around the prop shaft :/

I'll jump in on this thread instead of starting a new one. I have the same boat and have always had an ok wave but have slowly been tweaking it to get it better.
The key is definitely hole 4 or 5.
Secondary tab at 0 degrees.
0 cav plate on regular side
50% on goofy side.
Ever since we went from hole 4 to 5 I wasn't very impressed. Today we had more weird problems with prop wash but it seemed intermittent. Just when you thought it was ok it would spray off of the cav plate and slop water up onto the back hatches. Then I found the problem..... I put the tab menu into manual mode and the GSA tab was only deployed 99%. I toggled it down to 100% and all problems are gone. Best wave we have ever had hands down on both sides. I'm now so impressed with this boat. If I remember right isn't there a computer flash to fix this problem? If you flash it I believe you loose the manual override. I never thought it was a problem until I realized today that they weren't engaged enough when in hole 5.

I'll second this, for some reason from 99 to 100 cleaned up my regular wave this week.

There’s a chance that even though the screen sees 99 the ram might still have a 1/4” to go.

Hi sinned, if you are still on your '16 original software, you need an update. Does your surf tab still deploy around 7 or 8 mph? If so, the update will help resolve your issue. Flat secondary tab is key as others have stated too.

 

I struggled with my '16 F21. Sometimes I'd get 90% deployment, other times it would 99%. Without consistency, it is impossible to get your wave consistently good. The new software will deploy the surf tab to 100% while stopped, as soon as you select surf mode so it is always the same.

Oh cool!! I’ll have the dealer work on it. I was wondering why in manual mode when I attempted to put the plate down at idle, it would override and default back to zero. I’m still tweaking it but it’s getting better.

Too much weight causes all sorts of problems. Right now best wave is hard tanks full, PNP bags about 75%, center plate about 50%, and 650# in the nose

Once you are underway try going into manual mode and toggle your tab to make sure it's down all the way. My wave went from just ok to amazing by doing this. I was running full hard tanks and bags on surf side, bleed off for 5-10 seconds on off side. 440 lead in the nose. 180lb person in the bow and 700 lbs persons on surf side. I'm running pin position 5.

like everyone has said here, but ultimately i have found that the platform will keep you from getting the very best wave possible!

What is the reasoning on this?  Is it how the new platforms covers the tabs or did you previous platform dig in the water?  On my 13 when I watch my wave it doesn't seem the platform itself is causing any issues it looks like it throws a rooster tail because nothing is covering the tabs.  Thought about making a mud flap as a band aid.

the plaftform digs into the water coming off the back corner of the transom, the 17+ is shaped different than the 16. i put my 13 platform back on and it fixed all the issues i was having

If you have the right weight in the bow the platform will not affect the wave at all.

I have 650 bag and 200 lead and the wave is not affected by the platform. Everything full and bleed off wave side for 5-10 seconds. If you bleed off too much of course the platform will affect your wave.

I run factory 1800lbs, 750lbs in each rear, and usually 300 in the front. The platform is 8" underwater when sitting still. The regular side has a scar that is from the edge of the platform and the goofy side is garbage! Like I said, i went back to the 2013 platform and problem solved. I can ride behind the boat and watch the water hit the platform. to each their own, juts posting my finding. I also have a boat with not center tab which a lot of people say is 100% needed for a good goofy wave.
