    85+ Run Today

    Went out today, air temp. 72, water temp. 62, borrowed a 81 ring from SpeedSkiXP to try to get the boat off rev limiter, did some runs, best run today with lots of wind in 3-4 inch chop was 85.2 @ 8550 rpm and boat still on rev limiter, couldn't really get in a good run. Think the boat is capable of 86 the way it sits on a good day with low humidity, etc. Thanks to Mark @ RaceTech for all the help and time on the telephone for these past three years. These E-Tech Chargers have taken these boats to a new level. Can't wait to get the 8800 ECU, Rideplate mods and Pump Extension.

    How are you going to get an 8800rpm rotax ecu to work on your ski?

    I understand that the 8800rpm ecu's are only available for the 2007 and up engines?

    There are a few people who have done it but I think John is refering to a reflash or programable ecu.
    JK's boat is very fast. Once we get it off the limiter it should run 86+. I have an 80mm ring on the way hopefuly that will get it off the limiter so he can do some real speed runs without feathering the limiter. The weather changes so much from week to week here that every time we get it close to being off the limiter the weather gets better and it picks up rpm's and puts it back on the limiter. Thats a good problem to have though. Should be interesting! This is with a stock ride plate also.

    Thanks guys. I cant take to much credit for this as he has been working on this boat for a long time and it is making alot of power. I am just helping get it dialed in wich is proving to be a little more tricky than my stock ecu boat.
