I have a 31 I'm rebuilding currently just found it odd how few there were compared to 33-34 boats. It's nice to have people with similar boats to bounce ideas off of

I'm getting the hardware layed out on the transom looks like I'm going to be running the drives with the prop shafts at 3.5 inches below the bottom that is with the Imco -2 drives I have. I feel this should be good for my style of boating. I'm getting the steering cylinder mounts layed out next I'm thinking about running them in between the drives Due to the tabs interfering with the mounting standoffs I'll need due to running Imco extension boxes.

Nice boat! Keep up the work and pictures! Looks like you also got a real nice shop to work on it! I need a shop like that one day!

Honestly there are not a lot of Sutphen's regardless of size!

this is similar to how I want to set up my steering. with a bracket set up like this for the rams at the transom but I would need a stand off of some sort has any one done something similar with there twin engine boats. also I wouldn't mind checking out what you guys have done as far as stand offs for your steering rams on your boats.

WHY bother if you have boxes you surface..............you don't go 3.5 below the bottom what a waste of boxes and time and hardware

So with a prop shaft height of 3.5 below with running a 14.5 inch prop Im going to have 3.75 inches of blade Surfacing Correct?

My Math 14.5 divide by 2 = 7.25 inches minus 3.5 inches below boat hull=3.75" of prop blade Surfacing. with the 36'' drive center this seems to be a safe number to avoid pulling a drive out of the water to far when cornering

I appreciate the pictures and positive input Everybody im going off of a lot of tried and true knowledge but am always down for more schooling on the Sutphen boat
And Ill waste my money and boat parts however I want Ms Gangway!

fine you could do something really weird and call the factory and maybe get the right way it's done
if you have money to waste then by all means be my guest.....but don't blame the boat when you
have a slug on your hands.
