Fat Sacs, Good or Bad

Fat sacks are ok to use, just for ease of mind you should match your prop with the amount of weight you'll be displacing.
Stock props on ski boats are for skiing, so you have some options for a weighted boat, but then you should also consider that if you're still using the boat for ski you dont want a prop that will compromise skiing performance. So first you should state how and what you will use the boat for.

As regarding fat sacks, you should ask how are people weighting your same boat, as 750 or 1100lbs is a lot of weight for a lone sack and you could possibly need many sacks distributed along the boat.

Sumo sacks or Pro X series are nice. Sumo come with a valve for not spilling water when you fill them, on the X-series you have to buy it apart.

Thanks, that makes sense about having two sacs instead of the one in the back of the boat. To answer a couple questions, the boat is definetely used for slaloming and footing more than boarding. I like to board, but it is not the main use for the boat. As far as props go, I have a new 1442 ready to put on as soon as it warms up a little. Cant weight to try that out. Maybe I'll give the two sac method a try. I want to see what others have to say about it before I purchase anything.

you wont hurt a properly aligned transmission also

1442 should be a good prop for you. It has worked well for us ('89 w/ 1.23 trans).     We run 2 400 lb sacks, usually not full.      If you want to try surfing, just put 1 sack behind the motor, the other alongside.   We put in a aux power outlet near stern for the tsunami pump, big improvement over tossing the cord up front!

Hey Mark here's a thought for you... I see that you are in Illinois and we know there is a gathering at Lake Clinton in May so you could plan on attending, talk to those who are going and see if any are bringing their Fat Sacs. If so then you could try out different sacs and placements and see what works best for you.

Thanks for the input, we'll be attending clinton in the spring, thats a good idea to try them out and see what is the best scenario. As far as an alignment goes, it is on the agenda, been reading up it, waiting for a little more warm weather to work on it in the garage. Thanks again

Snobs, can you recall the rpms at 22mph with the loaded boat?
thank you for the info.

Luciano - I think 22MPH was around 2400-2500 RPM.

Doug - We don't have any weight up front other than the anchors & misc gear. The fat sacks are along side the motor box, so there is opportunity to place them more forward or aft. My son (whom all of this wake stuff is about anyways) will direct who he wants to sit where - sometimes insulting a female!

Our fat sacks are square, but I wouldn't think that even round ones would 'roll' - they squish out sideways against the gunnel & motor box.

Round sacks roll, I can tell you from experience!!!
