My 1989 SeaRay 250DA with a Mercruiser 7.4 / BravoI I/O has the original Bennett 12x12 trim tabs. Everything 'works' fine - I can get on plane, trim the boat level, and most of the time keep the bow at a decent angle and stop porpoising, but I've noticed that even when I'm pretty aggressive at moving heavy stuff to the bow (coolers, etc) my starboard tab is almost always fully extended, and the port one is pretty close. At times to keep the bow down, I have to use the power trim and leave the sweet spot - I can hear the engine bogging a touch. I'm getting ready to install the ATC system, and I'm thinking that I could also benefit from some larger surfaces.
LOA of the boat is 26' 9". From what I've read, 24x9 should be adequate, does that sound reasonable? Should I be looking at 24x12 or 30x9 instead? I'm assuming that going from 12x12 to 24x9 I can use the same pump and actuators, but that I'll have to move the actuators? Does a surface that large need dual actuators, or am I OK with a single?
Here's a shot of the transom of the boat (excuse the worn bottom paint). It's an 8.5' beam, so I'm not sure the 30" planes will fit.
Thanks in advance for any advice or thoughts!
