I'ts e deck boat so that shuold be plenty beacause 60mph is not going to cut it. As it is only one insurance co will insure this cat anyway because they are supposed to be fast might as well maket a bit faster.

What about your x-dimension? Maybe the lower unit is too far in the water?

I flew out there about 3 weeks ago to pick up my repaired stuff from the Ford dealer and Absolute Speed and Marine (from the poker run).....116 degrees that day and it took me almost 11 hours to get home after a trailer tire blow out on the 40, dead battery from sitting with the AC's and lights on in 116 heat for 2 hours......it was friggin HOT. :D :D :D :drink: :drink:

High Heat and humidity = +Desity altutude = Power loss.
Airplanes are the same way. On a hot muggy day you will see parts of a runway you didnt even know where paved.

The easiest way to get the 10 MPH back is to do what the rest of us do when its hot. Tkae your shirt off, place it over the speedometer while your running, then lie about how fast you went.

I changed out a center axle flat tire on the side of I-95 in 12 minutes flat AND I was wearing a business suit! (Took of the jacket of course.) I was on my way to a business appointment, and was taking the boat in for some work afterwards.

Havasu about 450' elevation. It doesn't help when its in the 120's either...

10 mph loss is high in my opinion. Heat will hurt some HP but not that much. I run a 502 mag mpi with a few upgrades and ran it a couple weeks ago in 115 heat there in havasu. Not much difference when it was 90 early in the day then 115 in the afternoon. I was actually surprised as I expected more loss. I do not like to run it too hard too long in that heat though. I think it is harder on me than the motor. :D
Bigger HP motors will see more loss. Just my expierence.
