Another 2800SX Resto

[Ramifications]

I haven't done much with high speed runs. I am still getting a feel for the boat and finally getting to the point where I know what she wants and when. More than I can say about my wife

I did raise the engines another 1", so that puts me 2.5" below the bottom in front of the engines. I may go up another half inch or so. I tried a set of BBlade Blasters and did not like them. Bow rise and time to plane was terrible along with a very unstable ride (much like the Hydromotives) and lost a lot on the top end.

Last weekend we ran a good distance with the choppers. We ran back at about 60-65mph around 5-5400 RPM's burning around 40 +/- gals per hour. At 4-4300 rpm's, she burns 20-24 gals per hr and makes 48-52 mph. The last little stretch in the creek before I hit the no wake at my ramp I hammered down. Tabs full up and I started trimming the engines up. Speed was slowly increasing and I hit the trim up one more time and the boat came ALIVE! She lifted up out of the water like a never felt before! speed went 70-1,2,3,4,5,6 at about 1mph per second and I had to back off the throttles with her still pulling hard since I was at the no wake. I think I would have been over 80 if I had more room. This speed was GPS and running against the tide, so add 3-5mph to the posted speed

My new Bravo 1's just came in the mail, so I will post back what I get with them. We have a long run coming up on the 27-28, so I should have some decent feedback on their performance after that.

Quick update on the run with the Bravo 1 props.

The all around handling and performance with the bravo's is hands down better than any other props I have run. Cruising down to our camping location with two adults, two children, approx 750+ lbs of gear in the bow of the boat and 100+ gallons of gas, we were cruising at 50 mph at 4200 RPM's and getting 2.1-2.3 MPG. After unloading the gear (but still had 85+ gallons of gas) we did some high speed runs and I saw 76-77 GPS and was effortlessly on the limiters at 6400. At top speed, she was so well balanced I could take both hands off the wheel and let her fly! I would try a bigger set of props, but I think these are the props I will need when I swap out the lowers. They don't seem as fast as the choppers top end, but are better by far everywhere else.

I couldn't agree with you more. I love my Bravo I FS...so much that I ordered a Bravo I XS for my G2. The nice thing about the Bravo I props is that Merc sells them in .5 pitch increments. So if you really want to dial in your set up, you can. The difference between the XS and FS (as far as I know) is the number of vent holes. The FS only has four and the XS has eight vent holes. The FS is aimed at four strokes since they make a lot more torque on the low end and don't require as much venting. The XS is aimed at 2 strokes as they need a little more help out of the hole. ALSO: Mercury Racing announces that they are coming out with the Bravo I LT (long tube) to create more lift with the prop to raise the entire boat out of the water more. If I were running a big Vrod on a 2400 BRX, I would look at the LT closely.

A quick update on this project. The boat is at BCB's getting some work done - transom, knees, lipless splashwell, glassed in cockpit floor and gel coated. I will also be building a new backseat, installing new front bolster seats and new side panels with speakers and storage. I am sending the ECU'a off to whipple for a stage 2 tune putting the 300's to around 340-350 hp and turning 6900 rpm's according to my phone conversation with Whipple. Can't wait for boating weather!!

Damn, I'm gonna have to up my game. BCB is a busy place.

If you would stop coming up with new ideas the rest of us might be able to get our boats done (there)!!

You may want to look into adjusting your trailer bunks so that the lifting strake rests directly onto and is perpendicular to the bunk.

They are pretty well aligned with the lifting strakes. I think the notched transom and camera angle is throwing your eye off. They do need to be adjusted forward and better alignment since I slid the boat forward for better balance with the added weight of the engines.

Here are a few updated shots of this restoration. The transom work was completed, along with the reconfiguration of the dash, a new cabin installed, and all New cockpit.
