I am Thinking of switching from a 200 PM to a 300xs on my 20ft Hydrostream Vantage? I was wondering what I should expect from the weight gain and If I should shorten the length of the jack plate from 12 to 6 inches? I think the weight will be in the 125lb range between the the two engines...the boat is solid and the transom has been beefed up. Thanks, how would you guess the handling would change? ....
