Agreed...150 OB is as balanced a powerplant for a V-20 as it comes...

My Johnzuki 140 4 stroke will move my V FULLY loaded just fine, and it gets 5 mpg!
 But to answer your question, WILLY's old V had a 115 on a bracket and he said it did just fine.

Since 150 seems to be about the best HP/MPG size to put on the V20, then what should I expect with a 175? I've seen these boats with 120 on the back and they still pull tubes like a ragdoll. Will fuel economy be worse or better in rough waters with the bigger motor since it has the extra HP over the 150? I want to go offshore with mine too out of Pass Christian, so I know I will be seeing 2-4 footers sometimes coming back from out there.

I use to get 2.5 to 3 mpg with my 175 yamaha, Like with anything if you hop on it you are going to use more gas. Some motors are better then others, but if proped right and tuned well you will get 2 to 4 on most 2 strokes

Dunno if an I/O is an option but, I like the 165 inline 6 Cly. Speed wise it hits 40 with a light load but, I usually cruise at 25-30. In rough seas it's very stable if you take it easy,..usually about 20-22 knots. Maintenance is easy, and parts are plentiful.
Weight wise the I/O helps keeps the boat trimmed evenly at rest and high transom has never had a drop of water come over it. When I needed to repower I'd considered a bracket with 150 Suki but, at 12K for the changeover opted to jus replace the 165. 1800.oo is what I paid for the new crate motor. 1000.oo to install.
