I spoke to hydroturf about cutting a piece for the center rear seat step area. I remove the seat so that we can enter and exit without stepping on the cusion and If a passenger needs a seat I put it back in. Hydroturf is cutting me a piece at a charge...but I really think it should be a part of the kit. If you would like the same then give them a call. This will make boarding the boat slip free and keep your cusions clean!

I'm still waiting for my kit..damn mail, but I can't wait to get it installed. I ordered Dark Blue for my blue C-180

Just an update as to how my boat mods are going. I'm not sure if this will stay in the C-180 index or be moved to the Tech forum once I get some pictures and how to's completed but until then.

I just finished installing my Rotax Racing thru-hull exhaust. This includes drilling a hole in the back transom so that it exits the rear instead of in the pump cavity. The exhaust is now 2.5" aluminum pipe instead of the black hose and I have removed the stock resonator. This should make for one mean sounding boat and it will be quieter then having it exit into the pump tunnel. There seems to be a resonating frequency (2500-3500) at the stock exit and it's way too loud for me. In stock form it's bearable but once you get rid of the stock resonator it's just too much.

I also installed a cold air intake that draws cool outside air from the side engine compartment vents. I used a 4" flex hose with a 4" flowrite waterproof filter on the end which goes directly to the supercharger inlet.

I am currently mounting a XSPOWER external intercooler and have removed the stock intercooler. This will yeild much better air flow and reduce the inlet temperature considerably.

I took my pump apart and re-pitched my impeller to 12/19..stock was 10/21. In checking the progressive pitch I had one blade that was to spec with the rest being out of wack. One of them was waaay out and had burn marks caused by cavitation. The wear ring had normal wear but I flipped it around so that I will be starting with essentially a fresh ring. I plan on either installing a Stainless Steel wear ring or getting the Rotax Racing motor mount which reduces driveshaft deflection. It's the deflection that seems to eat up wear rings and a worn ring causes mucho' performance loss.

I installed a new stereo as well:
Aquatic AV CD player mounted in glove box
2 wired remotes: Cockpit and Transom mounted
Waterproof auxillary input for mp3 or satellite radio mounted in cockpit area
Sony XPLOD 5 channel amplifier mounted in glove box
Polk Audio 6.5"s in stock locations
8" Bazooka Tower speakers
2 10" Aquatic AV subwoofers mounted under the back seat and firing towards front of boat
HDR-610 Humingbird depth finder mounted in stock intstrument cluster

I might install another set of Polk 6.5"s in the front bow area but want to hear how current set-up sounds on the water first. The bass is unreal and should be even more kick-a$$ once I get it on the lake.

Future Mods:
* I may change out the Supercharger impeller to a Riva or Rotax Racing
* Researching some possible trim systems to get rid of the porpoising and slow on-plane times
*When the funds allow I will consider the Rotax Racing ECU but only if I'm not satisified with performance of the existing mods. I want fast without sacrificing reliability.
* I would luv to install some Hydroturf but I'm still waiting for them to produce a pattern and a kit for us C-180 owners
*I am trying to find an affordable boat tabel similar to what comes on the Utopia

Well thats it for now...I will post some pics real soon of my mods and share my experiences once I get on the water.
