Twin outboard center console build

[ScarabChris]

My initial plan was a triple rig. I even bought 3 of the outboards. But these things are heavy, I would have needed a 46-50" hull to hold them.

I'm using these ESCs http://www.offshoreelectrics.com/pro...rod=dh-prb2314

OK I did a test run, the boat is stupid fast for what it is. Even with the motors to high the boat fly's. I think some 3 blade larger dia props would help with the cavitation. I can bring the motors down a little too.

Pics coming.

Looking good! i was thinking about doing a triple outboard setup on my a super hawaii hull i had laying around but was not sure if i could fit all the ep1's and how it would run. what esc where you planning on running? can't wait to see the finish product!

Just keep 'em greased up with a tight fairly tight mesh and they should last longer.

I dont think you'll need counter rotation on the props at the speeds you are going to hit. Plus, the clockwise motor wont like it and will obviously spin slower. I ran a twin EP1 brushless setup on a larger hull without counter rotation and it worked great until the brass bevel gears got eaten up.............and they are nearly impossible to find. Although your stock motors should be fairly easy on your gears.

lol, so I guess they won't last very long with my BJ26 motor attached to them huh?

Yes these are EP1 motors. Yeah I was looking at the mounting instructions for the cav plate hight. In full scale boats you have to put the cav plates an inch or so higher than the hull bottom for every foot away from the transom they are.

So on my real boat the engines are 3 feet off the transom and the cav plates are 3.5" higher than the hull bottom.

Shouldn't be much different here, though I know I am well over that. Keep in mind the motors are just dry fit right now. I have room to move them up or down.

I have already ordered 3 blade Venom counter rotating props with a slightly larger dia. If the motors run hot I will just pull the water from a hull mounted scoop and run a hose into the motor.

Another thing to keep in mind. This is not going to be built for all out speed and long high speed runs. This is more of a scale build and will only see short bursts of speed.

These look like EP1's --- AQ's mounting instructions indicate that the cav plate should be even with the bottom of the hull. Your location maybe fine. Just check on the temps of everything after a 2 minute run!

A couple of us have done twin O/B builds and if you decide to, you can go to a larger prop if need be! Just need remove some of the water feed for prop clearance!

On my Cat build I went with counter rotating props and it went pretty well until the smoke appeared! Got to hot and I didn't check the temps & poof the Genie appeared!

Ficken AWESOME!!!! I love those Sports. When I was younger, 1985, my Dad was purchasing a new Wellcraft. I begged him to get a Super Sport. He got a 250 Sportsman instead... Which is still a cool boat.

When I was a kid, my dad bought a 1979 thunderbird formula 302. Everyone called it a cigarette boat because that name corresponded with any large fast offshore boat back then. I thought I was the coolest kid on the block!!

I have seen forward only too, just too lazy to go digging and link to it. I think it was on the package when I got mine.

Oh ya and KILLER build!!! Kudos to the non-trad builds

Chris, unless Im missing it, I think the Novak smart stop works both ways. Ive never used that type, so I could be wrong. But I was on Novaks site and dont see anywhere that it says Forward only. And I didnt know the OSE one did not operate in reverse... hmm. Learn something new everyday!

[Make-a-Wake]

I dont see where it says that...............here's 3 cell that i cant find "forward only" on.....shouldnt make a difference i wouldnt think

[ScarabChris]

I see those LVCs are for forward ESCs only? The ESCs I have have reverse. I want to be able to use the reverse.

The LiPos are 3 cell 11.1 volt.

Are you going with the stock 27t 550's? Its gonna be a fun build...........i like the fact you are staying brushed to keep it scale in speed.

Yeah I'm leaving the stock brushed 550 motors. I don't need to go that fast though I'm sure it will hit 25+ MPH.

If I want to go 50+ I'll bring out my big gasser....







And if I want to go 60+ I'll jump in the full scale version above.

[ScarabChris]

Thanks, yeah I have always loved the Scarab Sport. I have had this one for about 8 years. I re-did everything on the boat. Pretty much the only thing original is the hull and engine bracket.

Wellcraft made them in three models. The 26 foot Sportster (aka Sprint) 30 foot Sport 302 which is what mine is and the 34 foot SS (Super Sport) Thats the one I really want but they are hard to find.

Here is a shot of mine taken by a buddy last weekend running from Ft Lauderdale to Elliot Key which is the upper FL Keys.



I'll be giving the RC boat the same paint scheme as well as painting the motors to match.
