| That seems like a long ways. Am I going to run into any issues with my cables being to high? And what will be the issue with it being to high?

Cables and things should be just fine. you are going up about 3-1/2 inches to possibly 4 inches, but as you showed in your previous pictures, your anti-ventilation plate is about an inch below the bottom of the boat...

| Well found out there was a sticky spot on my throttle and I was not getting g WOT. Got the boat up to 41.5 MPH last week but I am still having issues getting the boat to plane. My spray is coming off the front 1/4 or 1/3 of the boat. I'm trimming up as far as I can before my prop starts to blow out. Any recommendations? |

Sounds like you need to get a prop that has more lifting capabilities, but 41.5 on that boat with the 115 4 stroke is getting close to the best you will see....
If you have not moved the motor up off the transom more, the lower unit is still holding you back a touch as well. With more lower unit out of the water, the less drag you have, thus more speed. I believe this will be a big part of the equation here...
I do tend to think you need a prop that has more tip cupping to it to help lift the bow and trailing edge cupping which would lift the stern more as well...
Something like this prop on the link below is worth a try, but you would be much better suited to find a dealer that has a demo prop program so you can go out and test different props to find one that will do what you are looking for it to do.
Although you have a mercury engine, if you can find an exchangeable hub system that fits an older Michigan Rapture, Ballistic or BRP Raker propeller, you'd have some options to try...
The raker is a great prop, and it has 15 splines, but most likely would not match up unless you can find an exchangeable hub system for it. The older pressed hub models will most likely not fit.

| Thanks Steve, I'm totally happy with this speed, it would be nice to get a little more lift out of the bow though, how would raising my motor affect how much i am able to trim?
Also I don't see the link you mentioned above

Hiya,
Having more lower unit out of the water may allow the prop to lift the entire boat more, and potentially let it do a more efficient job trimming the boat. In some cases, getting to higher rpms than where you are now allows the prop to stay hooked up better, thus allowing the trim to work more efficiently as well. It's kind of like when you you have too much trim at lower throttle settings that the boat will begin to porpoise. At speed, the prop can hold the boat up, but at lower throttle settings, the prop is unable to.
You may also find if you have a bunch of gear in the bow, that may be playing a factor as well in how well you can trim. If you have a full livewell up there, two batteries, and gear, it will be harder for the motor to trim the bow up.
IF you wanted to really tweak things, you could get a manual set-back plate to mount the motor back off the transom just a touch further. This would change the center of gravity of the boat more to the stern, thus giving the motor more ability to lift the bow with less trim.
And yes...I forgot to post the link..

| Thanks Steve, I'd like to see if I can get some lift without having to buy a new prop. I also would like to have the motor lifted but I don't want to have to move it more than once. I guess I'll see if I can get it moved and see if that gives me any more lift |
