    How fast should this go?

    Just bought a complete stage three rotax rxp 04 new from Toronto dealer- love its "schnapp!!!" What should the numbers look like? e.g. 0-20 mph, 0-40mph, 0-60mph? 0-80-82mph? Just woundering from others. I feel no need to gps it. On Lake Ont. it's in it's own universe.

    What do you mean make it faster? Are you having problems with it?
    How fast is it now?

    Did you buy this as a brand new turn key ski? If so how much did they hit you up for it?

    Lucky guy I think?

    I have not gps'd it so take this with a grain of salt- I'm not the type of guy that will inflate numbers because I'm always looking for more, thus if you lie there is no more. I think it will find its way to 80-82mph when beside a stock 06' RXP. Where it really performs is how it gets there- you need strength to control boat in turns and in stand up position. As far as I know it runs great and sounds great- my only question is that I think my rev limiter stops me at 8450 rpm, it should have more. As for the price let's have a guess at turn key perchase.

    Your rev limiter is not stopping you at 8450. Your impeller pitch is. Rev limit with that ECU is 8600.

    $21,500 USD ... turn-key and installed

    it's an 04 RXP.... when were the parts installed?

    when did you buy this? recently or awhile ago? from who? ... obviously the parts came from Underwood, did he do the install, or that dealership up there he used to work with did all the work?

    rev limter could be stopping u there if it's the old 1st generation racing ECU.... so i dunno where u got the ECU or when they got it or when u bought it.

    Mark's boat

    This boat was run by Mark (I believe at Lake Havasu.???) It was Marks Demo that I bought off former Dealer with 1.5 Hours on it. As for the price the first guess of $21,500 usd was close but still a little lower and it included the usual stuff like trailer, cover ect...Also the price was tax in= 15% in Canada.

    A new ski, with those mods, labor and tuned out should run about $24,000 USD
