I need some advice on where the drives should be trimmed at 2007 42 lighting with 700sci and #6 drives when driving? Using the drvie indicator I only go from 6 to start out to 5.5 when on plane. Is this right? I know they don't need much trim any help would be great.

4 3/4 - 5 too much more and the props will blow out.

shouldnt you be at 1 when you take off? drives all the way in

A #6 boat is reversed.

This should give you a starting point. Drives in and tabs all the way down to plane off. I get the most efficiency with the drives tucked all the way in until 3000 with the tabs at 2.5. Come out 1/2 click from 3000-4000 with the tabs at 3, 1 full click from 4000-4500 with the tabs at 2.5 and 1.5 clicks to wot with the tabs at 2.5. Pull the drives in a half point at wot if there is a cross wind.

On the drives indicator all they way down is below the 6 so when you say 1 click do you mean one number?

You have to remember that the drive trim indicators are reversed on a #6 boat. Sounds like that may be your problem. BTW......I have been to Ogden, UT. Very nice up there in the mountains. Where in the heck to run a 42 like that? Sorry, I just had to ask.

correct, 1 click = 1 number from all the way in on the drives and all the way up on the tabs. If yours is like mine, 7 is in on the drives and 1 is up on the tabs.

You can also look at smart craft. They have a digital trim setting if you toggle through the pages. On our 38\700 and 6's shows on the mechanical gauge I dont trim too much over 6, but the smart craft will show 7.4 just a little bit more accurate than the mechanical gauge. They are not calibrated the same, so that can be confusing. Also..the trim on the throttle, up is up and down is down. The individual trim switches on the dash to make the drives go up you have to push what would be normally the down side of the switch.

Thanks for all your comments, it was a big help. aTX427 my boat is set up the same as yours so thanks for the help. FtnDlr we have lakepowell about 5hrs away, flaming gorge 3 hrs away and lake havasu 10 hrs away. We also have a couple small dams close by to play at.Thanks again for the comments.
