I need a little help.. I just bought a 04 Alumacraft 1425 Fisherman V- bottom boat that has a 06 mercury 25hp 4 stroke on it also with steering console. The problem I am having is is it just will not plain out. The boat will run about 20 mph with the front end up in the air. I put two trolling motor batteries up front and put a whale tale on the motor, this does keep the front down but still will not get up on plain like I am use to. My question is it just under powered? or is there something else I need to look at? I know I had an older 16' v bottom with very same layout as this boat with an older 25 hp Johnson and it would pop right up on plain and go also that boat would do about 20 mph. Any help would be great and thanks.
