What boat, motor, and current prop do you have?

im unsure of the current prop, but its for higher speeds rather than towing.

most people get the Mercury Hi Five in your situation - when I had an I/O I had my eye on the 19 pitch, but I wouldn't go any higher than that.

To improve your hole shot you HAVE TO know what prop you have now.

Props have a "pitch" and "diameter". The diameter will almost always change when you change the pitch of the prop but focus on the pitch. The lower the pitch number the better the whole shot. If you have a 19 pitch now, change it to a 17 pitch.

Some people advocate really low prop pitches like 15 or less to hold speed, but with that engine a 17 should give you a pretty good punch out of the hole.

I would also recommend that you move to at least a four blade prop. Stainless steel is also better then aluminum but they are a lot more expensive.

i was looking for the same thing and contacted acme and they hooked me up with a great new prop. best purchase i have ever made for my boat. i lost a little in the top end, but i can hold wakeboarding speed (low 20's) much better now.

We had a Cobalt 200 with that engine and switched to the high 5 and it worked very well.

Mercury High 5 all the way. 5 blade monster. I used to have one on my old I/O. That thing was a monster coming out of the hole, plus it held speed fairly well, and had great top speed for what I expected.

ok...i found a high 5 stainless, but its a 20 pitch. is this going to work out good if i have 2k# of sacs in the boat or should i find one with a lower pitch?

I'd go to a 19 at least. Usually a store that will sell you a prop will let you try it and exchange it for another if the pitch is not quite right. You might well need a 17. I'm guessing that you know that 2k# of sacs would overload your boat's rated capacity.
