Dana products are being made but Dana marine has closed their doors. Marine industries west is manufacturing the Dana products. Just placed my order today for a set of Flow Tourques

Blownhammer have you done anything with your ECM? With your experience with CMI and Dana do you have a preference? Did you have your prop done at Bblades?

Stock ECM, the HO makes max power at 5100, I didn't want to turn it faster and hurt reliability in long term or have to run 93, the Dana's were awesome, no complaints, i was hearing about the problems with getting the danas when i was looking so i opted in a different direction, i was going to go with lightning myself until I priced them with the 60* turn in the collectors, my rage has the side exhaust, that extra exspence put me right there with the etops, and the cmi is full stainless over steel, that's what made my mind up


I used cutting edge for my prop, hands down best decision I could of made......

If you don't mind me asking what were your costs for the labbed 28 from cutting edge?

How many RPM's are you turning at 78mph with the labbed 28 blownhammer? Did you try the 28 first before labbing?

I can't really answer that because auggie went above and beyond to get me where I'm at, I started with the cutting edge bravo style, he made 3 different 28's for me, a general lab, labbed with diffuser cut down, and a 28 turned to a 29, my boat was in the rev limiter with no gain on the first, ran 76 @ 5100 with the second but had horrible blow out in midrange, and couldn't turn the 29 past 4700 @72, after all that I told him I really wanted him to get me a bravo 28 and lab it, he did no question asked and that's when it ran 78 @ 5100 in Oct last year, my boat just did not respond well to his bravo style props, even after all that he said run it the rest of the year and if I wanted to tweek it more this spring send it back, all I paid was shipping out to CA and he adjusted and sent back no charge, that customer service speaks volumes to me

what type of paperwork did he have you provide for info before labbing your prop? I am debating on buying a 28 seeing how it run stock and then sending it back in for labbing if it doesn't perform as I'd hoped

I started with general lab, meaning a trueing and thinning of the blades, you will lose roughly 400 rpms going from your 26, you need to lab it to get the rpms up, I documented everything when testing, GPS speed, rpm, air temp, water temp, humidity, water conditions, wind, trim levels, fuel load, our rages like a good 6-8" wind chop, I'll pick up almost 2 mph, glass conditions I can only get 75

Thanks for the information it will help to reduce the experimenting that I will need to do. I look forward to getting my Rage dialed in this spring/ summer. Currently my max is 76 on GPS with one person no gear and a 1/4 tank of fuel on each side. The stage 2 Whipple really did seem to help the boat attain top end well. I am hoping with the right prop and the Dana that I see 80 but I am fairly optomistic.

80 is what I'm shooting for, I'm just not sold on the Whipple reprogram, I'm pretty sure mine would run 80 at sea level, I'm at 800', which also plays a big role in tuning a prop, some have met or exceeded 80 with Whipple stage 2, headers, labbed 28, good luck, sad part is it will never be fast enough!
