that is an awesome boat ,how big of a servo do you need to move the outboard assm under power

HiTec 25Kg steerage servo running flex push-pull cable.

I'm using a Hitec HS-5765MH. Handles steerage ok.
Playing with props, motor heights and drive angles atm.
Props tested so far range from X438, X440, X445, X448 & X450 2 blade, onto X840 & X845 3 blade threw to X945 2 blade.
I don't have a shortage of torque, making an easy 6000 Watts @ 32,000+ RPM so pushing 1.9 pitch is not a problem,
however the torque throw has a habit of lifting the LHS sponson clean out of the water at anywhere near full throttle.
Might play around with motor off-setting to counteract the torque throw.
COG is at 25%.
Everything runs below 40 C after a hard run at full stick.

Known as RB123.
Pretty much whenever its flat enough and the wind isn't blowing too hard.
Be careful - it's very shallow in places.
Hope to catch you up there sometime soon.

Hey Kris, I spent a lazy hour and 1/2 today remanufacturing my motor mount.
Dropped the leg 12mm and offset to port 4mm.
Gone back to 2 degrees positive too as opposed to 5 negative.
As you might see in the vid, she buries her nose when I back off throttle because of the negative trim.
Hopefully, dropping the prop deeper will cure the power wasting "slurpies" of cavitation and the offset will help to prevent the port sponson from lifting at full noise.
All done in shiny polished billet aluminium.
Trying out a 3 blade CNC X640 tomorrow if the weather is good.
