 |
|
Okay. I need a need a new prop on the boat, the one that is on it is horrible. Bad sluggish out of the hole. So what prop should I get...sorry I don't know what it has on it now. And I need about four hundred pounds up front. My wake is extremely short and wide and I always have tons of people with me so I need something to kinda even it out. So I was thinking lead weight would be the best so that I don't have to worry about running more lines and stuff or filling it up everytime I go out.
Also, on my left rear tank the hose keeps coming unscrewed from the bag. I can't figure out why its doing that. Ever happen to anybody else

How much weight are you running? The stock connectors that are used are not very good, mine used to leak all the time (04 SSV) I upgraded bags and replaced the connections....leaks are gone.
I'm assuming you've messed with te wakeplate adn moved peopel aroudn in the boat w/o any luck.
wakeside.com has good info on props and weight ran.

i have a 05 21v also. here's your fix: get the gg front locker bag & put it in the front locker. take your stock front bag & put it on one side of the engine. purchase another front locker bag & put it on the other side of the engine. the gg front bag is @ 1100 lbs so you should have no need for more weight. the 2 stock front bags ( that should be on either side of the engine) are @ 700 lbs a piece.
if you do this you will definitely need the wb prop. i think mine is 14.25 x 14 if i'm not mistaken.
this is the setup most of the 21v owners are running on this site. you're in for a surprise the first time you load the boat down. |

I am running 2,100 pounds right now, all of them are even at 700. I will try to get new conncectors.
I don't want to get into upgrading my bags, for the simple reason that I will be getting rid of the boat next year and if I get lead weights then I can use them anytime anywhere.
Yeah I have fooled around with the plate and everytime I ride I have to get the people to all go to the front of the boat so we can plane off.

Zack_Attack, this was posted along time ago by Matt from Skiers Choice, I think it pretty much sums things up. From the sounds of it, you've got too much weight in the back of your boat. Anyway, check this out...

OK, hopefully I can answer some of the questions that have been asked. . The price difference is because we order a lot more of the standard props than the optional props and at the quantity that we order, that does make a big difference (all Supra and Moomba boats). The standard prop for the 21v is a 13.7 x 17.5 CNC 4 blade prop. The optional wakeboard/altitude prop is a 13x15.5 CNC 4 blade prop. The optional prop has a smaller diameter and pitch which makes the engine turn more RPM's. That is the only thing that it does. The higher RPM's are an advantage at altitude because with the thinner air, typically the engine will not produce the RPM's necessary to optain higher speeds or power. For wakeboarding, the higher RPM's quicker allow the engine to provide a higher horsepower when planing off when the boat is under a heavy load. That is why heavy boats take so long to plane off. Notice your tach next time you take off and you will notice that once the RPM's get closer to 3000 or more RPM's you seem to have more power. That is due to the horsepower curve. More RPM - More Power. That is why we call it a Wakeboard/Altitude prop. However, and this is very, very important. We only recommend this prop for those that will be running loaded boats all the time. If you run this prop on a boat that is unweighted at full throttle, the higher RPMs are more than recommended and could lead to problems. That is why Marty's boat was hitting the rev limiter. The rev limiter is there to protect the engine from RPM levels that are too high. Carb's do not have a rev limiter so doing this with a carb engine could lead to very bad things. Also, the less pitch will lower the top speed of the boat. If top speed or running the boat often unweighted is important, we do not recommend the wakeboard prop and is why Marty is running the standard prop instead. Many times he has to run across the lake to pick up people and that works better for him. Also, the higher rpms will burn slightly more gas. Again, the idea is to get more power for getting on plane. Also, putting less strain on the engine might help durability for down the road. I have also found that the wakeboard prop and the power that it helps produce help the perfect pass on heavily weighted boats. It really seems to hold speeds better.
Another note on the larger bags on the 21V. Obviously, from a liability reason we have to recommend that you do not overload your boat, but if you want to use larger bags in the back of the 21V you might want to look at longer bags that carry more weight rather than shorter bags that place the weight directly in the back of that model. The "gravity bags" (19x19x42) that fit in the 22 SSV do not work very well in the 21V because it puts too much weight in the back and causes the wake to curl over. Rather than dumping half the weight out, I recommend you use a longer bag that puts more weight toward the middle of the boat, such as the standard front bag (16x16x70). About the same weight but you don't have to dump it out to create a big wake. Trust me on this one as I have run it both ways and definitely prefer the longer bags to the short fat ones. Actually the same holds true for the 24V, XLV, and even the Moomba LSV. Remember, you want to displace the whole boat for a good wake, not just the back of the boat!!

upgrade your bags and keep the stock ones for when you sell, you'll always have a use for 600-700lb saks regardless of what you own next.

UPGRADE! They already are upgraded. I spoke with a Supra rep last night and he told me that the stock bags in the rear are 200 a piece and then a 650 up front. I already have 650's (I think in the back) The last thing that I need at this point is more weight. I was talking to my buddy last night and we have decided that 400lbs up front should fix my problem. However, I want the easiest and most mobile form of weight. I am going to hit some of the pawn shops around here and see what I can scrape up. If I can get ahold of 8 50lb weights I will be in business. Of course this is not going to help my acceleration issue that much but it will at least give me the right length of wake that I need.

| you'll spend as much on lead as you will on new bags. dude, it's a boat....just a hole in the water you throw money into. bite the bullet & get the bags. then move on to the next project you want to do. |
