Hello, I realize I didnt buy a speed demon and Im not looking to ring every last bit of speed out of my boat, but I am interested in getting alittle more out of my 36'

I am currently getting 48 mph out of my setup now and I thing the boat has a little more to give me than that

2002 36' with twin 250 efi Mercs turning 3 blade 19'' stainless props. I believe the engines are turning 5400 rpms and the settings on the engine mounts are in the middle setting of the 5

Any useful help would be appreciated

Thanks

Bob

Something doesn't sound right there. At the Jammin on the James poker run I was running next to a 32 Concept with twin 250's for a good portion of the day. Spoke to the owner after the run and he says it is a 65 MPH boat. I know yours is bigger, but not THAT much bigger...

otis311

yeah, I know its slow. It should hit high 50's to low 60's all day everyday. $hit, I can run around on one and still do 30 mph !!

Doesn't Maryland Mark have a similar set up? Haven't seen him post for a while though.

Speed aside...do you like your Concept? Just asking because my next boat will probably be a CC.

Gladhe8er

Me too. I like the Donzi's and Concepts. 30 footer, twin 250's and I'll be happy.

I have owner atleast 15 boats thru the years including a 31' formula 29' Baja a Top Gun, Tiger and a Gladiator. The Concept is a GREAT all round boat that has many many uses. I have no complaints at all with this boat. I call it my Sport Utility boat. It can do just about everything. It just aint that fast, but who cares !!

Indy

Yeah...the 30 looks great for our waters, maybe even the 27 because it can go in the rack at Rex. A couple of Opti's or etecs and years of hassle free boating (relatively speaking of course) on the Sound. Tired of crawling around bilges.

Thanks Otis.

Bob,
Shoot a PM to NOMOGOFAST, and see where his motors are mounted at.

Motors are probably a little deep, I run the same motor on my 24 pantera. I turn a 21 pitch mirage plus to 5400, but the rev limiter is set at 5800, I will be stepping back to a standard 21 mirage, should get a few more RPM's. maybe try raising the motors a notch, and getting a tad bit smaller diameter props??? I realize it is a big boat for 250's, but I run 60 with one tired 250EFI on the little boat at the same RPM as you, I would think you could squeeze 55 out of it easy.

I agree you should try and contact MARYLANDMARK, he has tried every known prop combination and the best part is he wrote it all down and kept track of it. speed,rpm, mph etc. he was very helpful when I had my 30' lots of knowledge with concepts. good luck
