30 step props
 

what props do these boats like or anybody have a 30 and what do u run? rev 4 , bravo 1, tempest, hydromotive, or powertech?

Bravo FS is the way to go now a days rev4 garbage

I have opti’s not verado does it matter?

I'm running 24P bravos with 1:85 lowers. That's what the boat was delivered with. I told my self that I wasn't going to start chasing those last few MPH's and just enjoy the boat. At 65+ the boat is a little unsettled.

i appreciate your response what kind of power do you have?

300 Verados

26 Bravo 1 with dual vent holes.

300X motors I am still working on the setup.

What have you see as far as MPH out of the stepped 30 w/twin 300 Verados? The reason I ask is you mention @ 65+ the boat is unsettled. So just curious how far past 65 you have made it. I have a 2000 non-stepped 30 w/225 Optis and have seen 65 (on the GPS). My motors are mounted as high as they will go and at that speed she is trimmed out pretty good and beginning to get a bit light... But I think there is 1-2 MPH more as I wasn't on the limiters, just ran out of courage ;-)

My best so far is 73. My boat came with the motors in the 4th hole. I was having water temp and pressure issues. That's another story. I had the motors lowered to the third hole and my pressure and temp issues went away and I think the boat handles better too. The boat chine walked a lot with the motors in the 4th hole. I don't have a lot of test time with the new set up yet, but I don't think it will cost me any speed. I have to learn the best trim setting. Yesterday I hit 72, 2 people on the boat, FULL gas tank, and full water tank. I was turning around 6250 RPM. I'm hoping for 6400 with less fuel on board. That should give me another MPH or 2.

Good Numbers. A lot of people thought I was full of it stating I was hitting 65 with 225s until I posted the video showing the GPS. But it does take the right conditions and the boat being pretty light. I think I could get 66-67 out of it if I really got her trimmed out but I am really not out to set any speed records....... Loaded with 3/4 tank and 4 people I am around 60-61. I will say mine rides really well with the motors mounted all the way up. But they are totally different then a Verado...

Nice boat Dave M.

I have not got the motors out of break-in after the rebuild yet. But last year the boat was slow out of the hole so i am trying to create a little more slip but with the X most of the exhaust gets vented before the gear case so it might not help me as much as what it would on a XS. The boat with TQ master and 26p went 74mph and still climbing before hitting a water pressure issue.

Dave M, any progress? A buddy is having the same issue. Same setup, but a 2018.

He is considering selling it, as the boat is not stable over 65 right now.

The weather has not been cooperating so far this year. I think lowering the motors did help with the handling. Still not perfect. I'm usually riding around 50 mph, and the boat rides nice at that speed.

This boat is a 2018? With Verados?

I always seem to need to run some tab. My tabs are level with the bottom when they are fully up. Seem slightly odd to me. Other boats I owned had k-planes and were angled upward, when fully retracted. I usually run my tabs on 2 or 3 now.

I've had issues with chine walk with Mirage+, not on the Concept, but other boats. I'm running plain old bravos, 24P, 1:85 lowers.

Verados have five mounting holes. My boat was delivered with the motors in the 4th hole, meaning if they were in the 5th hole, they would be in the highest position. I had them lowered to the 3rd hole which seemed to help.

I boat in a mixture of fresh, brackish, and salt and don't think that should make a difference. My boat rides nice at 55, OK at 65 (better since I lowered the motors),

Did you try the bravos yet? Is the boat listed for sale on yacht world? Grey sides?

Concept salesman or dealer?

I am in the sales process for a 2021 Concept 30cc with twin 300 Verados. Now that you have had some time with your boat, can you tell me how the handling is at speed and what top speed you have achieved. Also, what are your impressions of the build quality? Lastly, if you trail your boat, do you have an idea as to the verticle clearance when on the trailer. Any information would be really helpful. Thanks.

The boat rides great in the 50-60mph range. The best I've seen is 73.1 MPH. It get's a little loose at high speeds, but nothing crazy. I use mine for tubing also, I can maintain 15-25 mph, not completely on plane, but not bow high either.

I am satisfied with the build quality. I had a few gel coat voids on the bottom which were easily fixed. I have a small stress crack on the corner of one of the rear storage compartments. The storage compartments in the floor do not stay dry.

I trailer the boat. The trailer I got from Concept, "Ultimate Trailers" is OK for the price. The boat loads and unloads easily. It tows good too. I towed it back to MD from FL. The top of the arch on the trailer is around 11 feet.

Overall I really like the boat. If I was to do another build I would do the open boat with big console and hard t-top. The cabin is pretty useless to me except for storage. There is a potty down there but my wife complains about it all the time. There is very little head room in the cabin.

Thanks DaveM. Really appreciate your insights. They are giving me food for thought on making the change from my current Advantage closed bow to a center console. I visited the factory but the only 30 cc there was in the process of being built so it was hard to get a feel for dimensions. My wife likes the couches in our cuddy. The front vberth is a padded storage bin in our boat as well. The ride sounds similar at similar speeds (although the Advantage will just about touch 80). But like your boat, when I get past 65 with trim coming up and I need to pay close attention to what's going on. The real problem is that 11ft height as my storage barn has a 10 foot entrance. Not sure I can change that and am not excited about paying for a new boat and a new barn. Love the look and open spaces on that Concept though and the sound of outboards versus a big block with headers (before I go completely deaf). I guess I am lucky to face these tough decisions. Take care.

Talk with Eric or Luis - they have an optional "folding" arch - a friend of mine had it on his 36 as he had a low bridge on his canal that, during high tide, didn't leave enough clearance.
I don't think you'll have any issues with build quality - Concept makes a great boat.

I have a 2008 30 with a stepped hull but with bottom paint. I have 225 verados but can't get past mid 50's. I am running 3 blades and i am amazed with the speed you get with a your setup. My motors are in the 4th hole.

I rode on a 30 (non-step) w/ 225 Optis before deciding to buy my boat. The owner said it ran in the low 60's. What RPM are you seeing? Gear ratio? What pitch prop?

6200 RPM 21P props. Not sure of the gear ratio. 2006 225 Verados. Took it out yesterday and really couldn't get it to break 50 MPH.
Maybe bravos will help?
Thanks for your help.

Ron

Your gear ratio is probably 1.75, or 1.85. Either way, your slip is very high, 25+. Maybe your motors are too high for the 3 blades to bite. Do you know where the cavitation plates on the motors are when you are running? I would definitely try bravos. I'm running 24P bravos w/1.85 lowers. My slip is <10%

I found 22p bravo 1's had to source two separate props to make a pair so they don't match (one is polished and the other one is not) anyway took it out and got 58 MPH at 6000 RPMs which is so much better. I can feel the lightness you guys are talking about now. Great solution to my problem for the money.
Thanks to all

I'm looking at a 07 30 with step and was wondering if the factory adding the setp fixed or helped with the porpoising problem that I hurd the non step 30s had. Any insight on this?

The step did help it alot and if you have verado you can run Rev 4's FS which give you stern lift and good handling. I used to work for concept and I did all testing so I can tell you all you want to know.

thanks for the response I plan on looking at a 03 and a 07 this week and weekend so i just want to have my ducks in a row befor i go. There is a 14k difference between there asking prices so just looking into every thing I can to figure one or the other or nether. I will be taking my normal tools to look them over and also my moisture meter. The 03 there might be wiggle room on the price but not so sure about the 07 and if there is probably not much.

The hull on the 30 is a longstanding, proven hull. That being said, I would opt for the stepped hull if both boats are in a similar condition.

Just picked up my 30 open with 300 verados and consistently see 70mph with half a tank of fuel and 2-4 passengers. Have seen 76 with 1/4 tank and just me on the boat but I'm still learning how to run the boat. As previously mentioned the boat doesn't seem to be quite comfortable over about 65
