I am new to the forum - have made Few posts and really appriciate the help so far. I just bought a 1978 ff to convert to a center console. It has a 12 degree deadrise- so it is modified v. I really want it run shallow and be as light as possible. There is no rot or soft spots at all in the floor. I am replacing part of it to install a new fuel tank further forward than the old one. The fuel tank in the ff was actually under a removable hatch. Can I put a short shaft motor -20"-out on a porta bracket and expect it to preform well? I was thinking of putting 140 on it to save weight and fuel. The original transom height was 25". What about cutting a tunnel into the back few feet? Has any tried this? I really only want it to cruise about 28- 32 mph. Also, if I use a porta bracket, will I need to install a low water pick up on the motor?ThanksOliver
