Re: Extension Boxes and Set Backs
Gary,
I did a little reading today about the Stelling 12" extension box.
The box raises the dive 1" in it's neutral position and allows for adjustments of 1" up or 1" down from there. The engine does not have to be moved. Vary cool set up...
Definitely the way to go if the best prop-shaft depth is not known...
Tom,
I would have to agree with JC on this one. Too many unknowns; go with the standard X and have some adjustment...

Re: Extension Boxes and Set Backs
I did talk to Stellings on thursday. Great guy, nice product. He did say that you would have to remove the Merc driveshaft damper on the flywheel to bolt his ujointed shaft on. Your call Gary.
I think I'll go with the Imco 3" and then do a 1 or 2" drive spacer to get the prop back near stock but still have the ability to go higher by removing the spacer if needed.

Re: Extension Boxes and Set Backs
Tom, I Do Hear What You Are Saying. But My Choice At This Point Has Been Narrower Down A Bit. John Has Opened Transom Already. Belive Me I Would Use Merc. Its Steering & Setback If I Could. I Am Not Going To Do Transome Over Again. Thats Why We Are At This Tough Decision Time. I Feel The Stellings Set Back With The Damper Removed Will Really Not Have Any Adverse Effects???? You Know This Was Real Easy On My First Invoice With John, A Simple 496 Ho. Oh Well, Lets See What Happens .....................gary

Re: Extension Boxes and Set Backs
Hey Tom,
I understand your reasoning for the Imco over the Stellings...
But let me just throw another thought at you:
How about a Neutral Imco box with a short Sportmaster lower on your XR drive mounted at the standard X dim.
This is basically the way MRD rigged the Zuperboat.
With a 750HP blower motor, she ran high 90s and with Mike's 575HP/540 she ran 85-87mph...
My concern with the Imco +3" box would be raising the engine 3" from the standard...

Re: Extension Boxes and Set Backs
From all the chat about balace I've been hearing here, I may just go with a neutral box and stock XR and see how it runs. I just read a email from Zuperboat and I'm thinking he could still use more prop in the water.
