How much set back

This answer may be very vague but people have been running any where from 10"-17" of setback on their Pulsares. I run 13.5". What's optimal is hard to say. You have an ultimate package with the 300. There's not a lot of those around. Setback will probably vary from the standard 225's. I would think you'd want to push it back another 4"-5" for sure.

Your 300X is probably pritty heavy, so you wont need to go back too far. I would try between 10" & 13". Get somebody to shoot some video of you doing some "fly by's" and see how much trim you need to get top speed, Your goal is to have the prop shaft as parralel to the water as possible at full speed. If you go with too much set back it can make the boat porpise at lower speed and you cant get enough negative trim at low speed.

I did hours of reseach this winter on this same question. I have a 2100br with a 225pro XS. In the end I found the best running all round 2100's use between 9-13" of set back. A number of lifts offer this. The one issue is that as you go further back the motor drops because of the negative degree on the transom so you need to choose your setup carefully to allow full lift.
In the end I wend witht eh Stainless Marine Jackplate and 7" setback total 11.25". The great thing about Stainless Marine setback is that is has about 3-4 degrees of negative trip built in. This should allow the boat to plane quicker and trim tighter at low speeds to avoid porposing.
I think you can get a 4" extension form Hydrodynamics

Jetmate,
Yes, my biggest concern is the porpoising issue as I already have an issue with this problem when the boat has 4 people on board. Although we all want to go fast, I do not want to further sacrifice an already rough ride at low speeds with a load.
Sounds like you've done your research...any advice??

For best slow speed and cruise trim in and jack down. For best top speed trim out and jack up. Think of your trim and jack as a manual shift vehicle. To start you're in first or lowest as you gain speed you'll shift up or trim/jack up. You'll soon find your best positions with loads and speeds.

Here is what i found about lifts on the 2100
CMC 10" inexpensive all in one and tidy lookingbut my not provide enough lift for top speed $1000cdn
Dietwiler More expensive, strong, ugly (IMO) all in one unit but required additional spaces to achieve 10" $1700cdn
Stainless marine. jackplate is very very strong, goodlooking, most expensive and has a pump that is mounted in the boat. In order to achieve 10" you need to add the mini-setback which is just a piece of aluminum art! It provides a built in 3" lift which compensates for the negative degree transom and provide a couple degrees more tuck in trim. $2400cdn ouch!!!!
I went the stainless marine becuase I wanted the best and best looking solution. If is had to save a couple of $$$$ I think i would just go the CMC. good product and great price.
If you read what users are saying about their rigs you will notice CMC users have everything in the top holes and ofter don't have enough lift with 10" setback. With the stainless marine you motor will be double bolted top and bottom and mounted in the lower holes and you should have more lift than needed.
I am trying to get my setup installed in the next couple of weeks (if I can find someone who will help in exchange for beer) then I will take a couple of pics.
sorry about my spelling.
