Recomended RPM range explained

[Crash]

How are your motor/esc temps? What's the total run time?

Thisis the best this set up has run.
Lower over all average amp draw.
Cool temps 120f
Extreme power
70 plus mph
Run times can be improved with 8s parallel of coarse..

Can you go up in prop at all?

[Crash]

Sure.
I have a 55x1.6 that pulls a little more amps but, not 300 continuous by far. It hangs bangs the 334 amp mark like the 52mm does at times.

Ok cool

All the huge amp draw happens off the line getting on plane. On plane I draw 100 to 200 amps on average

4 seconds sounds better! So running 8s with the same prop used less amps at full throttle than 6s?

No Mate.
If you read post 67 closely he can't use full throttle. so less amps with the same prop.
That's why I suggested a smaller prop for 8s to achieve a faster speed than 6s with less current draw.
Not good to run at partial throttle all the time.

Back to the start of this threads intention was to explain the reason behind the OSE
recommend rpm range.
Not sure we got to the bottom of that .

Those rpm recommendations were most likely suggested to keep warranty claims down. There's a ton of boats out there running close to 50,000 rpm regularly. The people who keep rpm down are the racers. I don't race, so my preference is to go balls to the wall!!

Strange, all these years I thought it was the other way around. Racers who know what they are doing can keep the RPM higher or lower depending what situation they are in. The suggestion is for sport boater who seek longer run time and constant change on throttle to keep a more realistic RPM in order to obtain a more reliable and fun fulfilling experience.
It is also a guideline for new comers so their initial entry into this hobby are not accompanied by failures.
Congratulations for your approach, not trying to be sarcastic.
Been in the pit with some of the best in the world in two Namba SAW events here in So Cal.....

Why should I start another round of argument, it's for people who at least can read.....

Post No. 2 in this thread had answered and explained very clearly.

Ok cool

I went out to the pond this morning I fit it with a X545 stainless steel prop that I got from Doctor props to see how a 8s would like that ran real nice real fast going to check the data but I have to assume its drawing less amps than the 648 I was running yesterday

So amps went up.
What the heck?
Smaller prop, I did pull 100%more often and longer pulls.
