how to trim engine for initial pull out of water

[drtachy]

I have a celebrity, 5.7L for skiing

How far down should the outdrive (engine) be in the water (trim) for the initial pull out of the water? When the prop is all the way down, the bow comes up quick then around 14 mph it drops and slingshots real fast.

Some one told me to put it all the way down. Is this right? feedback appreciated...

All the way in so the power is trying to push the boat forward versus lifting the boat out of the water.

Some trim all the way in for the holeshot, then trim up and adjust power once you reach optimum speed for whomever you are pulling.

It's something you'll get a feel for with experience. With my boat I trim down, but not quite all the way, to start and then bring the trim up as the boat gets on plane. Other boats may work best with the trim all the way in to start, you just gotta' experiment a little bit and see what feels best.

All the way down works best for me. I have a V8 also which makes it a bit stern heavy, so the bow would point to the sky until it planed out. The boat has always had trim tabs, but they didn't work. I just got the tabs working again, and now it planes out in half the time and the bow doesn't rise nearly as much. If the bow rise becomes a bother to you, you may want to invest in trim tabs. They just help keep boat more horizontal so the thrust from the propeller is pointed in the direction you need it to, backwards instead of down. I love em.
