Is it currently a twin or single setup? If its a notched transom you will have to use 20" shaft motors or jackplates to compensate for 25's - just things to think about.

If I mount them at the highest, the distance hull - propeller will be approximately the same as on my Whiteshark 215 with 25” engines, but around 2” more than recommended from B.W. I’m not sure if this matter enough to use jackplates/lift? With this installation I will almost double the engine weight – that worries in terms of the drains. Also I’m worried about exceeding the power that much, will this damage the construction?

The boat should do 46-47 MPH, propped right. I have 300 HP on mine and I think would be a better boat with less HP. Twin 25 inch shaft motors will not work on a notched transom Outrage 25; you would need 20 inch shaft length motors. Even mounted as high as they can go they will be 3-4 inches too low. Adding jackplates may not even get them high enough and it will compound the stress placed on the transom.

Why not use one of the engines and save or sell the other? Kevin 1988 11' Super Sport, 1987 Johnson 15hp.

I have seen people in the past raise the notch on the transom up 5 inches or so. I have to say though that Etec is the DEAL
