I have a 2007 DF140 Suzuki, first boat i have owned, 21' sea fox 216CC. Can the horse power be increased in any way? or just settle for this set up?

The 140 is the highest hp engine in its family eg those based on the same block/cc capacity.
Therefore there is no higher hp engine in that family that you could potentially swap out parts like ecu, injectors, intake manifold etc with to attempt gain hp.
Unless you trust one of those aftermarket ecu tuners to remap the ecu, then the answer is likely to be, no. -

These are the post that I know about where people are trying to wring a few extra horse power out of their engines. The link below IMHO is probably the easiest and cheapest way to go.
