Default Props out of the water

I rarely get a chance to push my boat due to family being on it, and then on the days I can, it's been flat. I've been reading that when you launch off a wave/wake and you get air big enough for the props to come out of the water, you need to pull back on the throttle to save possible damage to the drive. So when do you throttle back? Landing, just prior? And is the throttle going back at the same position or should there be more/less??

Thanx

Once the prop leaves the surface it speeds up quickly. The goal is to keep the prop speed the same out of the water as it was when it's in the water. As the props leave the water you want to pull back to maybe 3/4 of where you were and then push them back to the original position as the props re-enter the water........alot easier to type it than actually do it!!!!

yep



you have to develop a feel for it. I like to refer to it as keeping pressure on the blades, in other words you want the prop loaded as it re enters the water. It needs to be a fluid movement and takes some time to perfect. You will need to anticipate what the boat and waves are doing well ahead of the prop.



or you can just use the rev limiter like the guy that throttles the Wahoo Fountain

I thought that was the proper way, just wanted to double check. That is definitely going to be an acquired skill, and I don't get enough practice to do it well. Gives professional boat throttle-men a whole new respect.

Watch from about 4:00 on and you will see the best in the business, Johnny Tomlinson throttling the bacardi silver boat on the Today show. The throttle pretty much never stops moving.

This is an extreme case and he is pretty freaking talented, but it gives you an idea.
