28 Skater Repower--- 2.5 race to 300x's
After converting from 2.5 Race to 300X engines we put "Dust'n The Wind" in the water this weekend. The engines are still in break-in mode(computer limited RPM)...but I can offer these observations.
The boat feels bigger in mixed chop...because with the larger, lower RPM engines you have a lot more torque and power at 70-90 mph...so we use less trim and run steadily over wakes and holes that we used to rebound off of......Nice change.
I will be putting a few pounds in the nose to offset the added stern weight and leverage from the longer motors.
Top speed numbers to follow after engine break in is complete. Old max speed was 113-116 (depending on conditions).
I think I love these motors..........

Glad to here of the improvments.
Maybe I can come out to LI and catch a ride in that bad boy. We were tied up all weekend and only got out on the boat about a half day Saturday so I never contacted Joey.
Talk to you soon.

T2x,
I struggled with the decision 2.5's or 300x's at first. I'm very happy with my X's they shift nicely, run strong throughout the rpm band. These things really scream!!
The only negative that we have had to contend with is Mercury's new algorithms with regards to water pressure. We cant raise the motors to "optimal" speed height due to lack of pressure (anything below 9-10lbs). Also be very careful when they sense low pressure (or any thing else) they go into Guardian Mode NO WARNING just shut down to 3000rpm. So if you are testing at high speeds you may have your hands full (Not fun). Mercury has advised that they are supposed to give you a 4 second warning tone but this has yet to be the case.
Good luck with your new engines

Re: 28 Skater Repower--- 2.5 race to 300x's
how about being able to shift!!!! My friend with new 2.5's has popped two gear cases shifting his 2004 - 2.5 SS's
These 300x's really have a nice howl to them as well.
