The big heavy 25 footer has a 1995 mariner 200 offshore on it, and its just not cutting it. I would like to re power it this coming summer. I have a few options and im not sure what one will be best. 1). Buy twin 150's- probably in the 00-04' range. 2). Buy 1 mercury opti max 250- not sure if it will be enough power. 3). Sack up and try to find a 07' Mercury racing opti max 300. I would like to find the best option that will give me the best overall boat. Fast enough, enough power to get me out of trouble offshore. Any other options for new motors would be great to hear... besides a brand new 350 fresh off the line, don't have the cash flow for that right now!
