If you are having water pressure issues on either a 600 or 700, contact Dustin directly... he has fixes for this.

What is the statis on your project?

Sorry about taking over your thread, but you have helped me with a lot of questions

Thank you!

No issues with overheating, because the pressure was within the design limits at let's say 20psi at 4,000rpm's, but as soon as the power increases over 4,200 the buzzer's went off because the engine went into guardian mode. I suppose there would have been overheating problems if the warning did not occur, but keep in mind that my engines are stock.

You are welcome,

The motor should be running on the dyno sometime late monday. Dustin had to custom fabricate some parts.

The water pressure errors Dustin mentioned in his previous post have nothing whatsoever to do with his calibration. They are hard coded into the PCM from Mercury.

Dustin has the ability to change this calibration in the PCM... but it is probably not a good idea as opposed to fixing the water flow/pressure issues.

What kind of water pressure do you want to see

Do you agree that keeping the same props will keep some of the load of the NXT

Minimum 28psi @ 4800rpm, ideally like to see 32-35 @ 5200+.

Yes, same props will lessen load on the NXT and in the end, will be the quickest and fastest.

Are you saying the boat will excelerate quicker and have more
MPH with stock 6 blade harrings?

On the 700sci Stages I & II:

PCM re-program
Water re-route

No pulley change on Stage I - 780 hp
Pulley change on Stage II - 830 hp

You will have to contact Dustin directly for pricing.

Agreed - I have my pressure issues worked out. It was a rigging issue.

What about other people with the same boat? There are a fair number of fountains (38's, 42's) with 700's......... Fountain didn't help at all or get their chit together?
