hey bajaboss252, I also have a boss252, mine is a 97, do not worry about the clearance with the hatch. I have a 502 with the B&M 250, 1050 dominator, and a 3 in billet breather, top clearance is not a problem. The pain in the ass is in the front. i did not have to cut anything so I doubt you would for the procharger.

Hey BajaBoss,

I'm not worried about the top clearance, the ProCharger M1SC does not add any height to the 454 or 502. It's the front clearance I was worried about. I have heard of some people having to cut notches in the seat and so forth to get a ProCharger in. I am just curious to see an application similar to mine so I can see what other people have done to make it fit. If you look at the pictures, in my particular application the hatch LIFT is definitely in the way for a ProCharger to mount to the front of the motor...

Ted,
I know I owe you some pictures but we forgot the digital camera this weekend. I will get them to you. By looking at the pictures, it appears you will be fine. I saw you mention M1SC. If you are going with a M1, the intercooler will fit between the back seat and the motor. I put the M3 on and its' intercooler is somewhat larger is the reason it would not fit.

Mark,

Take your time, I am going on vacation Saturday for a week anyway. I do appreciate the fact that you are willing and able to post pictures of your application though. How much of a performance gain did you see with your boat and what prop did you switch to?

Thanks,

Ted

I went from around 67 mph to 81-82 mph with the Procharger install and ECM recalibration. As far a the prop goes, I went from a 23" Mirage to a 30" Bravo I.

Mark,

One other question, what are you running for exhaust on your boat? My boat has never gone over 60 MPH and it's 2 feet shorter than yours. I have the Q&Q II exhaust but I just pulled the mufflers off and ordered straight through tips with internal flappers. I am hoping this will gain me some HP. Also, when I bought the boat it had a Mirage 21P on it and I bought a used Mirage Plus 23P last year, though it did have some vibration to it. I sent it out last week to Bronson/Hill to be lab finished but I won't know what the boat will do until I get it in the water the week after next. I'll be sure to you let know how it runs with the reworked prop and new exhaust tips...

Ted

As far as exhaust goes, I run Stainless Marine. When I got the boat, it came with a 22" Bravo I and it would only run around 63 mph. I then put on the Stainless Marine exhaust, put on a Land & Sea Stern Jack and switched to the 23" Mirage and the boat came to life = 67 mph. Now, as I look back, that was an expensive 4 mph but hey, you know how it is, whatever it takes to get go a little faster seems to be justified at that time.

I have a 01 25 Outlaw w/502 and have been toying with putting a supercharger on. What was the final bill for your procharger if you don't mind. Did the install mechanic do the ECM recalculation or did you send it off somewhere. I would love to see 80 out of my boat and if it could be done for around 6-7k I may do it this winter. Thanks for the info!!!!!
