I run about 5000 pounds in my SE450 and it surfs at 3400. With ease.

Sounds like you need to drag your boat here this spring for a test drive!

What elevation are you at?

At right around 5.4GPH. It’s amazing.

Our local Supra dealer says they wont order an SE without a charger, and not that I see a lot of SE's around, but I have never seen a 450. At this point I would only pick an SE550. I'm also interested in a 2018 B52 23. Not sure how they are with the 440. Will that be enough? Any RZX3 with a 460 or charger would be good too. As a last resort, if I could find a great deal on a taps 3 Z3 or R23 I could go that route. The only boat that had a wave during the test that really impressed me was jasons RZX2 at mead. Other boats should have, but they didn't. So it's hard to spend $100k on a wave that I have right now. It just makes so much sense to me to dump $10k into mine.

I wonder if you would even need the charger in an SE. my 440 SE is a damned beast.

But SC is awesome for sure, it’s just expensive.

Two SE550's I've been keeping an eye on for a long time now.

The 15x11 doesent prove anything wrong. You can prop anything low enough to push through the water plowing at 10-11mph. There is a big difference between forcing a hull through the water that wont plane at surf speed vs the boat pushing over onto plane at surf speed. Big big difference. Maybe your boat is planing fine, not sure.

We are going to differ in opinions here so... but dakota was 1k lbs lighter, surfed at a really nice RPM, and didnt have any of the hull characteristics you are getting.... I tend to think you are either over weighted, not weighted correctly or the motor is hurt. Ill stand by that until you slap a blower on it and we see the diff. Thats just a whole lot of what iff to spend what? 10K? and at what expense efficiency wise? 15GPH?

I guess I didn't realize our boats are supposed to plane at surf speed. Just the opposite, in fact. I'm not sure what mine does, but I don't think I'd call it being on plane. I think Dakota was running 5k lbs of ballast. He'll have to chime in on that. But he did say he was never out cruising around pushing for a high speed. I'm sure all our surf boats are "overweight" when ballasted. That's no surprise. I thought the trend was 5k plus in these larger boats. Supra is getting close to that as factory weight in the SE. When I was propped to allow the use of all 5k the boat felt fine. MUCH better than our 21v felt with half that weight.

Yeah....kinda hard to ever go to smaller boat. And $55-$65K is the sweet spot for a nice boat.

I've come to the conclusion that ballast is just a pain in the butt. Those wakefoils look at least as fun as regular surfing and you can do it on much smaller waves. Wakefoil is #1 on my list for this summer

Soo...My recommendation is to screw the heavy ballast, use a smaller wave and have a much better time on a wakefoil.

I like the idea of the wake foil. Looks like a ton of fun. I have heard that injuries are popping up more and more on them. People just tend to find the foil during a fall. Kind of has me shying away from them, for now. I do agree that we need to focus more on other water sports though. Surfing isn't the only game.

Im not going to pick you out a prop because Im not anyones you know what... JK. I would totally help you but you and I both know that you have already decided that whats best is to go a blower, so you should do it. No one here is going to sway your mind, you have gone through all the work and the process and know your setup and have determined that a blower is the fix. You should stick by that.

Just know that other boats just like yours without a blower surf all day long at elevation with 4k lbs of total ballast and do it while having decent Rpm/cruise speeds. I would tend to want to figure that hiccup in the equation first before wanting to go up a hundred HP in hope of an instant fix.

Spending 10k on a blower on that boat is going to be a massive loss down the line. As long as our are ok with that then I would say go for it.

If it hasn't been make clear yet, I would love to NOT run a charger. I'm still very open minded. A 2:1 transmission is still an idea I kick around, but I'm having trouble getting the information I need on them. Do you really think there is another prop or a prop mod out there that will have me surfing at 3000 rpm's loaded with ballast? I don't think another prop will drop me 1000 RPM's if the four I've picked so far aren't changing things more than a couple hundred. That couple hundred rpm's is the difference between full ballast and half ballast. I won't even talk about a cruise speed though. My boat is clearly limited to about 2500-3000 pounds of ballast at my elevation. That makes for a wave that I'm not having a lot of fun on. My small kids love it.
Just to clarify. The blower will cost $6k at the most. Maybe a lot less too, if I get lucky. The other $4k in upgrades will come from a built surf system and plumbing in the rear ballast bags. Also some gel coat repairs I want to make. It would be foolish to expect to get all this money back when I do sell the boat down the road. So don't think I expect that. You kind of suggest the boat will actually be worth less with these mods done. Are raptor Superchargers going for less than, say, a 440 engine in the used market? I don't know.

Find a 2015 SE550, remove the factory surf system, replace with GSA, and have yourself a damn surf monster.... Or just use your fabrication skills to make larger tabs like 2016. That would be very easy and you would get exactly what you went on a demonstration of. For like 80,000.

I would do that in a heartbeat. SE550's aren't anywhere close to $80k though.

FWIW....my Z3 with 440 raptor, 14 pitch prop, 3000 water, 500 lead and 6 people would not plane.

Can you be really clear on the 5000RPM at 22 mph cruise situation? I initially though that was unweighted, small crew. But it sounds like it might be 3000 pounds ballast. If that's the case then I'd say your about right.

With the 2937 prop we were cruising around Powell this summer totally empty ballast, but we had 6 adults and 7 small kids. 5000 rpm's give or take and around 22 mph. We were not limited at this point. The boat would have instantly jumped to to the rev limited and we could have gotten a few more mph out of it. I was choosing to keep it at or under 5k.

^^^I May have had the ballast too far back that day...don’t know. Only time that has ever happened. I have no problems getting up to surfing speeds with the the same loading and setup. I just know that I gunned it and it kind of hit 15 mph and just hovered there. Hit the ballast drain and eventually it came onto plane and did just fine. 12 or 13 pitch prop is the ticket for ballast at elevation.

Anywho...I hate ballast.

[bsreid]

Wow it’s amazing how elevation has a play in performance.

Friends of ours Z3 with the 343 and more ballast than bakes has absolutely no problem getting up to speed. I don’t know the prop he has, but I know that he called acme and they set him up.
