IMHO and my life experiences.......dreams hopes and ideas can and do change along the way to produce what we call ...life..
I say that because in spite of "our"

initial plans for this boat , now about 6 years ago.. a couple major plans changed over time.
When I bought this boat. I bought with little reserve to cost... so to speak... after all I had read here and elsewhere it was going to be a trailer sailor...
I thought I would trailer it everywhere. I did trailer it a few times.. I did trailer it to SW Florida for a 4 month Vacation.. that idea

worked. For us it was to be NEW...... BTDT with used boats and didn't want to do it again with a boat a Sail Boat that I didn't have experience with..
I Almost invested in what would have been a
too small a motor .. I am SURE glad I didn't go with that idea! That idea ( I now call it a brain fart) was for a time, bouncing around on this board..... That would have been disastrous... I have needed that 50 HP big foot / big prop several times... and its just easier and better all the time...in EVERY situation
At the time in this area ( the Midwest) there was quiet a bit of hullabaloo about a 135HP being added to a Mac and a Transom issue..
I had already decided on a Mercury and I now felt I really wanted the Mercury 60 HP BF EFI..what the heck..a couple bucks more and 20% more HP same weight blablabla. The Marina/boat shop..not.... the dealer for my boat, refused to install it . refused to install anything over the "recommended " 50 HP..He was in over his head in litigations..$$$.
I had for my own personal reasons decided on a Mercury. In Part because I knew I wanted the Big Prop. I have been boating and water skiing behind a bunch of boats since about 1960. I know its not all HP it has much to do about the transferring of torque. These really are Huge Boats, Heavy Boats lots of displacement issues.. When was the last time you saw any 26' boat "sporting" a 50 H.P. O.B. on the back?
Why such a long post? Because the Motor is.... The Most Expensive addition , you may ever make to this boat and it will be the most costly to change later........
IMHO ......14" Prop.. then HP ......Nothing less than a 50......
