we went with 1 size under for better mid range and acceleration and she runs 85. Ran 90.6 out of the factory with the bigger wheel. And she is for sale !

Engines finally showed up - took about 18 weeks. Good problem for Merc to have, but a long wait. Currently being rigged. We are going to try a number of props. I'm not a huge fan of the Rev 4s, but will try those as well as some B1 combinations. I've seen a 39 quad 400 NT with modified maximus 5 blades. I don't want to mess with 5 blades, I'm afraid the torque may be too much for the lowers. Plus the NT I saw was sitting in the shop with 2 lowers removed, but I'm not sure why.

1st water test yesterday. Heading to LOTO today. Only details I got is it likes B1s better than Rev 4s, and I'm going to be happy. More after a Sunday run.

What a difference. Landed on 22 p B1s. Boat likes them way more than Rev 4s. On plane at 3k rpm vs 5k rpm with the Rev 4s. Stays on plane at 21mph vs 30. Mid-range acceleration way better. Only one hour so haven't stretched the legs completely yet, but hit 69 on a snotty Saturday afternoon, hi temps and humidity. Should end up 70+, but time will tell. This boat likes B1s way more than Rev 4s. Kudos to Big Thunder. Awesome job.

Ran over 100 miles yesterday. Added bonus, not only does the boat behave and run better, it averaged 1.8 mpg with the new set up. Use to average 1.5. Motors were set one hole higher than the factory sets them for Rev 4s. Ended up perfect for the larger diameter B1s.

I'm surprised at how little bow lift the boat has now out of the hole. Not as nose happy when running too. Waiting to see how it runs with the new wheels vs. the loaner wheels.

New props should be on sometime this week. I'm betting we end up tweaking them down a little get the last 200 rpm, but time will tell. I won't do anything until the engines have more hours on them and fall comes where some of this heat and humidity breaks.

MP- Congrats on finally getting your repower to the water.

Do you think your luck w/ Bravo props is related to the fact you own a twin engine NT.
I asked Terry & Trond both about B1's as well as the sportmaster lower case and they insisted that I stick w/ Rev4's.

Have you shared your findings w/ NT?
I'd be interested in why they believe your setup has benefited from the B1's

My first guess was right where you are suggesting about twins. Let's face it, there are not that many twin implementations out there. But with higher HP available, there might be more in the future, especially in places like LOTO where there is much less need for trips since you are not offshore. I'm guessing the trip implementations don't have the same issues I was having with the Rev 4 set up, those issues being have to spin them 5K rpm to get out of the hole, and can't keep the boat on plane at slower speeds, especially on bad wash machine weekends.

Big Thunder did talk to Terry regarding the setup. I've texted Terry to let him know how well the B1s responded to the boat. 22P B1s is the smallest pitch they offer. Honestly, I'm not sure, (well maybe I am) the 300s would have a chance of turning those props. Most likely not. Since 300s were the highest HP offered when I got the boat, B1s probably couldn't be considered. I have not reported any findings to NT. But I have sent Randy Kent a note on how well the boat responded to the B1s. I invited him to go out for a few hours to test it, he responded he would like to. Makes sense for him since he is the market for twin 34s. I may contact Matt Lamb with the info. I'm not totally into top speed, although I don't seem to be giving any of it up. I'm getting better stern lift with the B1s. The boat seems to rise level onto plane versus go nose high and wait for the props to bite. It keeps the level attitude at slow speeds, and when running in the slop. Plus there is the surprising benefit of 20% better MPG. I did not expect that.

If the trip implementations don't have any of the issues I had with twins, not sure what benefits B1s would have. Although, it would be really interesting to take a triple 350 implementation, raise the engines an inch, and hang some B1s on it. The B1s bite, and carry the attitude on the twin implementation way better than the Revs do. Just as fyi, my neighbor just picked up a new 32 Sunsation CC with twin 350s....turning B1s! So it may be just a twin benefit. Does spark your curiosity though.
