When I use to run the boat @LOTO in the Shootout, I would take everything out of the cabin, one thing that weighs a lot is the big panel that the v berth that the cushions go over and that covers where the ports potty is stored.

It’s fairly heavy and it’s pretty far forward,
so if one could make something out of lighter material,that would be a gain

you could take that out of the cabin and throw it in your newly created trunk
and see how much that affects things

Yep, that thing is higher, my potty is in the head and my 12”sub is in that hole Just got back so I’ll post and update.

TEST #1. OUT and flat water. I may check water and test again later today or tomorrow again depending on water.
74 degrees, low humidity, slight breeze, flat A$$ water. Not even a lil baby chop, lil baby glass w/ a lil rolls..

Any way.
Same height as Rev4, 5950-6150 @ 75-75.5mph
15.95 slip.
1 engine seems to have off a little. Tried to fix before with local shop by matching props and it flipped to P higher rpms.

Less stern lift, needed more trim to get bow lift at WOT. Less chine and went away trimmed out, but close to the point where is started slipping more.
Cruise was good at 300 less rpms at 50. 4050 at 50mph, mpg was 1.61, so that was up a lil from 1.53
But slip was higher at 17.54 (using 25.3 according to BBlades for 26b1)

As I lifted the motors, rpms rose but not speed. Once I got over 6200, I saw the 1 mph increase, but needed a lot of trim to get it there.
Tried 1/4” increments up to 1.75 inches higher (1 3/4”). So that would put me in 2.5-3” below the hull. (But 4ft back still)

At its best height around 1” lift, I was able to get 76.5ish at 6250-6400 rpms, but that last bit of rpms was trim to get the bow up.

Definitely needs to be labbed with some cup. I’ll try again this after noon if we get some chop. It’s never this flat around here!

Good news was that I was able to trim out enough to get the bow up and stern settled, but had to trim too far to get to that point and started to slip more.… i.e. need cup.
Even thought it was that high had about 17.33% slip and right up to 6400 on the Port motor.

1 motor is runs a 150 rpms differently. Should be able to balance at labbing.

I really need to test with a lil 6” chop or so to get at fair test run.

Can try putting some weight in the stern as well… from the bow, but definitely needs baja cup to get the bow up.
Labbing with added cup and get rpms to 6350ish in cool weather.

Will need to try IN as well, since I know that gets the bow up.

But based on this run, Ill need Labbing with cup and then can find sweet spot on height based on RPMS I need.

Round 2 Prop testing.

77 degrees. 8mph winds with 6-8” chop. W/ 8-9mph wind. Ran slightly cross wind into chop and crosswind down chop.
Not perfect water, but better than the glass flat ass water I had before.
I could probably pick up another 1-2 with some 1-2ft chop!

Best wot 77 but had to trim out to get rpms up.

77mph @ 6150/6350 rpms (trimmed the F out). 18% Diff of rpms 200
73ish @5800- 6100 depending on trimming OUT conservatively . 14.78 to 18.9% as I started to trim out.
70 @ 5300/5400 at 12.6%. (Diff of rpms down to 100)
65 @ 4900 at 12.29%
60 @ 4600 at 12.88%
50 @ 3900 lat 14.3%

Lowered motors to original settings with Rev 4s as it had less slip and I can trim out to get bow lift and rpms needed.

So Labbing will need some cup and rpms! Keep slip down and gain rpms on top without as much trim needed.

RPM Goal right now would be 6350 ish for cool weather and still hit >6200 during summer, but can still use trim to gain a little if need, 100 or so.

That was a quick 18 gallons of fuel! LOL

Also, it was odd that rpm difference started at 70ish mph at 100 difference and then 200 off at WOT trimmed OUT above 6k rpms.!


No tabs needed, Stern felt settled down and Bow was higher, but needed Trim to get RPMS and could feel more bow lift which helped get to 77mph !

I think this is the right height as cruise slip % was lower. I may even be down another 1/4” from before.

Shipped stock 26p B1s to BBLADES yesterday.. Stay tuned!!

He will have a few options as I can still raise my drives to reduce drag, so if Brett can get the bow up and reduce the slip, I should see some gains!!

Ok… this took a while, apparently Bblades closes for several weeks around xmas to new years.

26p B1 Labbed, Brett said he labbed with 27p recipe with cup and had to match all blades and cut 1/2” off the diffuser’s.
Blueprinted the hull and sharpened edges and ended up removing the 3/16” of hook in the last 12” of hull and smoothed 7-8’ forward.
The hook removed is definitely noticable at slower speeds below 40, though trimming engines or tab down slightly controlled it.

Need some more testing for sure, but touched 80 mph with 1.5-2ft sea’s.
Previous best was 78 and ran 77 with light fuel and 6ppl on board. Low fuel and weight in the stern seemed to run faster, but could easily get to 75-76 in flat water with 6ppl and over 1/2 fuel.
