The 21 is not a VP part, but I got it from Volvo dealer. When I got the boat, it had the stock 3 blade 23p aluminum prop on it with a slight bend in one blade, so I sent it in for straighten and balance, and bought the 21p 3 blade aluminum from VP. I actually like the 21p prop better. It gets 49 mph at 4800 rpms and a nicer holeshot, compared to 43 mph at 4400 rpms on the 23p prop. Looking at going to a 21 or 20p 4 blade stainless, but having a difficult time finding one with all the specs to fit my boat.
The hydroturf is indestructible. I also have it on an old jet ski for about 6 years, and still looks brand new. I have spilled oil on it, grimy muddy feet, dogs toenails, bubble gum, shoes, and standing up on the wakeboard on it with a fin, and never seen a bit of wear or damage. If it gets REALLY dirty, use a scrub brush and soapy water, scrub it a little, hose it off, brand new again. The bubblegum my nephew picked up from a warm parking area, and I waited until the afternoon when it cooled down, and scraped it gently with a knifeblade, and after 45 seconds, you couldn't tell it was there.
I like the stuff so much that I bought 4 sheets (ended up coulda done it with only 3, have LOTS left over) and did my entire boat. I pulled the nasty old carpet out and used it as a template, then cut some other parts out using butcher paper layed down on the floor, and outlining with a construction pencil around the textured "non-slip" areas on the floor. I even cut a couple of custom pieces for step areas on the boat, a couple of "bald" areas under the seats, under the anchor stow for noise reduction, and a couple on step areas on the trailer.
If it ever cools down around here, I may line my ski locker with strips to reduce noise.
Here is a pic of my "almost finished" boat. I ended up filling in those bare spaces under the seats with a c-shaped piece on both sides. There are two strips where the back seat passengers put their arms, which is the same place you step on as you enter the boat.
It appears to be expensive, but when you start pricing carpet, it ends up being close to the same price. Be sure to pay extra for the 3M adhesive backing...it makes installation VERY simple and clean.
