My friends 2007 292 only goes 68 on gps stock. How can you hit 74? Salt water?

What boost are you running

Gotta love those prochargers though. I love mine!

My 2006 6.2's run to 5200 rpm before the rev limiter kicks in. This only happens when airborn since my stock 6.2's can only turn my 28" Bravos 5000 rpm!

No other changes except going to 1.5 gear and you should see 87 mph at 5000 rpm, assuming you can turn that rpm after the gear change, and it sounds very possible.

Great to read your 292 is running strong. Do you have hydraulic steering? How is the handling? Someday I hope to be running the speeds you are working towards!

I have been told that tachometers can be off compared to what the computer is reading, so maybe bouncing off 5200 rpm in reality.

I think the power is there for the gear change if I go that route. I still have to watch the throttle getting out of the hole as it has more then enough power to blow out the 32s just like it did stock with 28s.

I do have hyd steering and it still tracks great at speed. The bow lift was definitely noticeable after the prop change.

I have only run in salt water since I have owned it and it is pushing 5 psi of boost. I was using a friend's iPad for the 74 number, and I am guessing it wasn't too accurate. My guess would be that I am around 70-72 mph stock.

I picked up the ProChargers from a good buddy back in Virginia. He had them on his 2001 292 and he ran 86 mph on GPS by way of his rev limiters changed to 5500.

Great to hear she is handling the added HP. I believe these 292 hulls can run fast before running into handling issues. They are flat boring in anything other than really rough water with stock power.

This is the best I have seen in perrrrfect conditions. Typical is 68-70 mph.

My 292 will chine walk on flat water at 80mph. If its choppy chine goes away! Glad to hear prochargers are working for you! I had 25 outlaw with 496 and procharger and it worked great. Put 180 hard hours on it with 0 problems. Make sure u run good fuel. If you predetinate with boost you will kill cast pistons. Also I would add oil coolers. 6.2s do not have any and run oil hot stock!

Are oil coolers relatively easy to install? CP Performance has a good selection online, but I would be interested if I could do it myself. Boat has spent too much time in the shop this season.

I wish I had that Smartcraft display!

I know that feeling! (spending to much) Yes oil coolers are pretty easy to install. I bought mine from cp with power steering coolers all in one and mounted in place of factory power steering cooler on back of engine. Just make sure you use braided an fitting oil line. I just ran line from oil filter to oil cooler and then back to engine.
