The question is are you going to use the extra power. They are basically the same engines. But the higher powered one is turbocharged and maybe even intercooled??? I don't know the higher powered ones well. With a turbocharger and intercooler you are introducing things that could increase maintenance costs and potential problems. IOW, the engine is more complicated. So if you had a choice in a vacuum and you don't need the extra power, then the 135 would be the better choice. If you do want the extra power in a 32 foot boat, which I'd assume you are wanting to plane, then the 225 may be more desirable. You will find most people on here prefer the NA version of that engine. It has an excellent track record as a slow turning low load engine.
