Jcap,,, Thank You, For Your Wisdom With Y2k And Answer About Set Back, Ext Box, 7", 12" I'm Just About Done With The Box's. Guy's I Think I'm Calling Jc To Put My Boat Together 600 Hp & One Xr Drive. Done. Time To Enjoy The Boat And Stop Thinking AbOUT A Extra Mph Or Two.....................

Baja;
THats what I was telling you in the PM. Quite alot to do about nothing it seems when ya get down to it

Baja, JUST-DO-IT!
Maybe your right. Most boats run and handle alot better with the box. And if you got 3-6 mph it would be a good investment of $1700. But here I see too much variation in set up so lets move on and turn up the boost or something to get more speed.

TOM. 3 - 6 MPH FOR 1700. I DON'T THINK THAT COULD HAPPEN. EVERY ONE WOULD DO IT. JCAP SAID IT JOHN HAS BEEN SAYING THAT ALSO. NO ONE CAN BE SURE WHAT WOULD BE GAINED. JOHN WILL CHECK OUT ONE LAST OPTION FOR ME. OTHERWISE "OVER FOR ME".

Hope its not one of them new Volvos that pull instead of push...

Baja, I've see it time and time again out here. Close friends that installed Imco box and got enough leverage to use just a little trim so the prop is pushing forward instead of trying to lift the bow also. Easy 3-5mph increase.
The reason why most people don't do it is because it's an afterthought and too much trouble with the insallation and trial to get it right.
However I think I'm in the same shoe as you. We're getting too much negative info.

Gary,
Mainly, it's a pain in the ass to install the 4 point mounts. In my opinion, it's worth it. I agree with Tom.

So BajaGary, your still thinking of an Imco box?

This Is It. No Stellings........not To Keen On Merc, Its........no Big " A " Drive..........what's Left ??? 2 Choices... Yes The Imco. But That Does Involve Re Do On The Transom...........last And Very Possible The Most Logical, Just Install What We Have.

Why the redo on the transom with the Imco? Going with the 3" rise?
