Shockwave 26 Repower/Improvements

[ECSURFER84]

Here is the finished paint job and I finished assembling the transom hardware. Custom printed logos and 3 coats of clear ontop of everything. Should be ready to rip while I'm on vacation.

looks awesome, what a great paint job and really dig the name too. make sure to get a video of the main voyage!

Very nice looking!

Thanks guys, It's not quite what I hoped for a flawless paint job, but I think I did pretty good for Rustoleum rattle cans. I built a temporary spray booth, so I think that really helped with the dust control and crap getting into the paint. The Epoxy fix that I did on the transom left some air bubble pockets that I should have filled, but oh well. Learned a lot I can apply to my 32" v-Hull build.

Paint looks good. Something unlike all the others. I like that.

Well, some changes for project Slingshot. Sticking with the 1500KV ProBoat motor and ESC. Testing revealed that it ran much cooler with lower overall amp draw than the 3000kv setup. I'm stepping up to 4S and I'll choose an approperiate prop and think that will suffice. This has been a really challenging way to learn about boats, and I all ready see that this would have been so much more worthwhile in another beefier hull, but I bet a lot of you can relate. I'll post some updated pictures soon.

Updates from the last 5-6 weeks. The 1500kv runs nice and controlled on 3s with cool temps on every prop I have. On 4s I'm cracking 30mph and have been able to hang with a Blackjack 29 and Supervee 27. I was noticing some chine walk, but dialing in my trim tabs and making sure the rudder was not sloppy has seemed to help that issue. Current state is running 4s with the ProBoat 1500kv and 45amp ProBoat esc. I plan on upgrading that ESC this winter to something like a 120 amp unit so I can run some more aggressive props. Learned a lot this summer!

So Update for the wintertime, it just started snowing in Chicago (UGH) it's not even Thanksgiving, expecting 4-6" into tomorrow. I'll be running an Aquacraft 2030 with a new ESC, just trying to decide if I go 180amp or not, thought it might be nice to have a backup since that is what I will be using in my 32" mono. Wanted dual water cooling for this hull going forward, decided to try something similar to what ProBoat uses. I always get great waterflow out of the port, much more than rudder pickups i've seen on my dad's BlackJack29 and Uncle's SuperVee27. Also picked up some props to try my hand at sharpening and balancing.

I decided I wanted to go with a .187 felx cable assemble from OSE and run without the liner in 2016. So New motor collet is nearly touching the stuffing tube when loosened up. Needed to move the entire motor back so that I have room to clean the tip of the cable and tighten the collet. Took some aluminum and made an extension bracket that bolts to the existing motor mount. This gives me enough room, but I think I am going to make some type of support for the opposite end of the motor to provide some support. Turnigy 120amp ESC will also be going in to manage the AQ2030 motor.

Almost ready now, upgraded Turnigy 120amp ESC in place and plumbed, motor support piece epoxied in, rudder linkage cut and bent. Need to measure and cut my new .187 flex and put the rudder back on her, then leak test.

For the most part everything weny well Sunday on the first water test. Nothing blew up, nothing was leaking! I'll be starting to sharpen and balance props, collect data and GPS in the upcoming months.

First Data Log:

AQ2030 on 4S
40mm Graupner Prop

RPM = 29,761
Motor Temp = 100.3
Max Watts = 1,135
Max Amps = 75.63
GPS (Garmin Forerunner 205) = 26.0mph (Seems kind of low to me, runs were straight for over 7 seconds, need to validate with my cell phone GPS)

Garmin GPS definately not accurate, I ran it on my son's Traxxas Slash and was getting 20mph while my phone app recorded 27. Need to retest with my phone in the boat I guess.

Two new sets of turn fins to try. Fabbed out of aluminum, tapered leading edges. Modeled after Darin's OSE turn fin and also the Aquacraft Revolt 30 turn fins. Trying to eliminate some of the skipping in turns for this hull.

Nice progress on this build. Where do you run your boats locally? With Google Maps and some weekend scouting in the car, I've got two spots within 30min of my house downtown.

[Tamelesstgr]

Luckily in my back yard in my subdivision pond. Ultimately I will be swapping out the power train into a new hull in the fall. With the increased speed this narrow hull doesn't have very good handling anymore. Going bigger and wider over winter with a Jet Chopper hull.
