That large roost means you either have the strut set above the ski or you are getting too much lift from that prop. You need to keep the prop buried so all the thrust is forward with a small thrust cone...JMHO.

the strut is buried right on the ski "cant go any lower" i know and for i have heard this thing should be barking at 60mph with this setup then again you could put 5 of this on a race and no one will run the same prop or setup

Is the strut set neutral when boat is sat on a flat surface.

the strut is flat on the ski

you should try to post some pics. i also agree that it doesnt sound like the rpms are low. have you tried moving the strut up? what does that do? have you tried to angle the strut differently?

[Serpents811]

I was on the phone today with joe from Zippkits as he was watching the video and his opinion was "the boat looks great and it's handling the way it should however the rpm doesn't sound like the should" , I'm coming to find out that the etti speedo like to be wack full throttle after plug in ones or twice to adjust throttle range so on that note I might not been at full throttle on that run

What timing is set on the ESC? If you use an ETTI timing can be set to 2dgrs - 7dgrs - 15dgrs - 20dgrs (or something in that order of size). Besides, what is the weight of the rigger ready-to-run?

The timing on the speedo is set at 2deg , I dont like running a lot timing and as far as weight goes thus boat pretty lite maybe 2-3 lbs

Try 15 degrees

[Serpents811]

Try 15 degrees

Wouldn't that be a bit much for in runner

[eric_laermans]

No, I run my 1535/5 2-pole inrunner even on 19dgrs without any problem (only more ampdraw :-))

My bad, I thought you had the 4074 can size. Yours is a d wind so I would start around 7 degrees with that one. 15 isn't too much for an I runner tho

[eric_laermans]

1535 has a 28mm can-size, 4074 is two sizes bigger (36mm - 40mm).

A 4074 has a lot of torque and is too big for the Hydro II (NAVIGA). But it can be fine for fun-purposes where runtimes aren't an issue.

i'll give that a try next

[Serpents811]

Ok I recalibrate the speedo today and set the timing @ 7deg and adjust the throttle range again it def sounds more aggressive out of the water will see next club race

I used same motor on my jae best prop was octura x648 depending on water conditions 65-70mph super reliable.
