    I don't know of any prop shops up in Canada. It sounds like your prop is out and has to much slip . The Rpms are a little high if your your tach is right . Your motor height is real close plus or minus a half inch . The closest prop shop that is number one for top end is DAH propeller. Talk to John Jankey . You will be happy . He is pricey . But it's a lot cheaper than new . At 3" below pad and only getting 15 lbs get your water pump changed . It should be a little higher than that . If the prop is new and the water pump fresh then I would lower the motor to get my Rpms down to 5850 .

    I just tried a tempest prop on my 98 hydrasport 196 with 200 Johnson and only running 60 MPH. The prop needs to be reworked. Probably add some cup. My boat has run 68-70 MPH in the past with a Trophy plus prop. Contact Kawartha Prop in Buckhorn Ontario. They are a great help. I would assume your prop needs some work to create better lift.

    Mine is a 2000 model but same boat and motor. I have my 25P tempest set at 2.25 below with 20 psi but can't turn nowhere near that RPM. I see the mid 60's with less RPM's. I have had my prop worked though, and if I push it through the chine it will climb to the high 60's.

    I have a 2000/200efi as well with a 24 tempest plus, it ill do 70+(before i dinged up the prop) but close to 6100 rpm, i think 3.25" below pad. On the negative side the hole shot sucks, especially with water in the livewell and hard to maintain prop bite i the rough stuff but no chine walking
