Adding Sacs to an I/O

Has anyone ever added sacs to an IO such as a bayliner. I dont usually ride behind it but taking a trip down to shasta and some family has one that I will be ridding behind. I really want to see if I add weight if it increases the wake size with keeping good shape and stays solid. Anyone else ever do this. If so where did you add the weight?

I can't speak for your specific boat, but in my experience the best way to run an I/O is to put extra weight in the bow and then trim up the outdrive between 1/4 and 1/2. Trimming the outdrive will clean up the wake and the extra bow weight will conteract the added bow rise from trimming.

you may not notice much unless you add a lot of weight....and by the sounds you will have a few people in the boat. the ultimate problem is that the boat most likely has a high pitch prop for maximum speed and if you start loading her up you may have problems planing(thats why weight has to be up front)or holding speed. Otherwise what eubanks will be the best short term experiment that will work.

my i/o:

1,000 lbs triangle bow sac
150 lbs on each side of engine = 300 lbs rear.
2-4 people in the middle = 300-600 lbs center.
trim up 1/2 - 3/4 and its respectable for an i/o.

its what i got for now and it works well for me.

I also have a 14x18 4 blade prop.

Well I will have 2 500 pound sacs and a 750 pound sac. So I will have 1750 to add where I want or need. Probably wont fill them all the way up. and I am pretty sure that its pitch on the prop is good for getting out of the hole and getting on plane. Its a bigger bayliner and already throws a decent wake. With some good shape. I usually ride behind an X-star and a malibu. I know it wont really compare But I am curious on how close I can get it to be like those. Thanks for the info guys. If you have any other input let me know. thanks.

so it sounds like messing with the trim is the key to fine tunning the wake...

My Cobalt likes weight up front as well. Currently running 1100 up front and 560 in the rear. With a little trim, the wake cleans up nicely. Plenty on wake for me and my crew.

oh ok. so more weight up front then in back and have the trim up some... sounds like thats going to work best. we will see. every boat is different...

Like everyone else posted weight is good and some trim use! In a buds old boat which was a Bayliner we just used a 750lb sac and layed it on the floor all the way up to the bow and trimmed around the 3/4 mark.

How was the wake. Big and solid? Could it compare to V drives?

Yes, if you trim it correctly you can get a solid wake in a lot of I/Os. Big would be relative, but if it is set up it can be decent. One of the biggest wakes I have ever seen posted was from a cabin cruiser I/O but that is not your typical I/O.

i have an ebbtide 210 i put 550 in ski locker with a 250lb in each side with a lil trim work......and it cleans up real nicely...and mine compares to some vdrives and the wake is as big or bigger

650lbs in the bow, 3 people in the boat, one in the water. trim about 1/4 way up. throws a killer wake. supper firm, clean, and gives pretty good pop

wow. thanks for all the input. Ya that wake looks great.

BTW thats a 22.5 MPH and at 65 feet. the wake looks about the same at 70 feet if you kick it up to 23.5.
for the time being though, im working on a backroll and dont want to worry about clearning both wakes so im riding a little short

Oh ya. I do that too when I am working on new stuff.

i just wanted to let you know.

I'd put the 500 or the 750 right up front as far as you can get it, the first 500 in behind it and the second 500 across or just in front of the back seat.

Most of the time on our boat we run about 500 up front and nothing in the back, not counting crew. Once the boat gets it's motor back I'm gonna play around with adding some weight to the back.

Thanks.
