What is the appropriate engine shaft length for dual 150 engines on an Outrage 25?

For the mid-eighties classic hulls (notched transom), it would be 20" shaft power plants mounted directly to the hull.

bwguardian is correct but the 20" shaft with counter rotating engines are becoming hard to find...

Many people are using twins with counter rotating 25 inch shafts that are on brackets with the engines raised up 5 inches.. This keeps the powerheads high and dry. Some people even use setback brackets to get the engines further back in cleaner water.

This is true, just be careful with the bracket you use as before I sold my 25' Outrage I was considering re-powering and looked at too many transoms that were cracked because of the extra stress. Do not skimp on the attachments. One thing I did look into (which was actually cheaper) was to take a counter rotating lower gear case and install a 20" shaft. My boat had big trim tabs and was reliable so I ran her as she was built (making adjustments with the tabs), it worked well; then I decided to get a bigger whaler.

JimU- I have a 1985 Outrage 25' Cuddy with CR 150 Mercury EFI with 25" shafts. I have them mounted on a 5" setback jack plate and as Joe says they are mounted up about 5-7" above the transom. I had them 2 holes higher but I was getting too much cavitaion when offshore so I lowered them yesterday. I can email you photos of the set up if you wish.
