Weighed my boat yesterday & Prop talk
We have a fork lift at my marina that has a digital scale built into it. Not sure how accurate it is, but what the hey. With just over 3/4 on the gas gauges, which by all indications is under 50 gallons a side, the boat weighed in somewhere around 9900 pounds. We figured it would be well over 10k. I guess dropping out the liner really does help on weight.
I figure the AC unit, fridge and microwave are not calculated into the factory dry weight. Right Pat? Plus all the chit I keep on board.
But, I can't get the motors to spin up over 4900. Even with empty tanks and just me on board. I know labbing these is the answer, but I just don't like having 8 razor blades hanging off the transom cause we spend alot of time in the water back there.
I have a buddy who just rebuilt his motors and is banging off the rev limiters with his stock 30's. How will these affect my cruise? I loving what I'm getting out of these 32's. I can run close to 60 at only 3500 rpms!
Clark?

I weighted mine at the landfill on the trailer last year before the whipples and Bmaxs and it was 12,800.Called Myco about my trailer and they said 2500 lbs.1/2 full of fuel so thats about 700 lbs so real close with a liner to yours.Forgot about 300 lbs of beads too.

I am right at 10K-10.1K. I don’t pull over 4900RPM with the stock 32’s either. The labs I have are not sharp at all and I am getting 62mph at 3700 RPM (which is optimal consumption via smart craft for the 525 (1.82 mpg), and 87 WOT with 3/4 tanks. I just had them pitched to 32.5/ 33 and will let you know what they do this next weekend. Brett thinks they will pick up 2 mph on top and 2 mph in the mid with the new mods. I was pulling around 5300 with them being 32 labs. I have the serial number if you want to send yours to Merc or Brett at Bblades.
The Maximus at 29/29.5 pitch and 15/14 is probably the best cruise prop. Talk to Mark about that. His mid numbers were outstanding.

Very good numbers Clark! I would be very happy with that!! I guess Brett does not lab his props the way Throttle Up does. How much to have him lab these 32's?
I know Mark is getting outstanding numbers with his 5 bladers. Problem for me is they are drive killers down here on the lower Chesapeake with the big water we regularly run in.
