    Spager,

    Everybody is going to recommend to get a tach first.

    Hey i didn't know you had a 2005!! That is way low even for a stock boat. When I got Amy's 2005 - it has been 66.9 right off the showroom floor and so have many others that have them. That speed your getting was the stock speeds for the 2003's and 2004's off the showroom floor.

    Ouch!

    Are you at a high elevation? and when you got that number are you using the neutral position on trim or 1 click "bow up"????

    Hey Spager...good to see ya over from Riva

    You definately need a tach...try 5-6-2-6

    The last adjuster will take over the high speed...it should come in around 5500 rpms

    You dont really have to worry about altitude cause your baro sensor will self-adjust

    I haven't seen an 05 but in pictures
    but I remember someone posting on the Riva board that there 05 ski ran better on 87 octane fuel rather than 93 maybe someone that has experience on this can chime in weather it is so or not I didn't seen anybody mentioning it, just a thought

    that has been the case in may situations. Those boats with the stock heads are designed for 87 only.....Some have said that anything else has slowed them down by putting anything higher in it (changes the fuel detonation). Almost all aftermarket heads are requiring 93+ due to higher compressions.

    Did you check if the transom plate is up in the hull where it belongs if that is down it would be scrubing off a lot of speed?
    on my 01 one side was up were it belonged and the other one was down a 1/4 of an inch
