I need some help. We are going to purchase a Bayliner 185 for our first boat. We are really on a budget and would like to get away with the standard 3.0 135 hp engine. I could upgrade to the 4.3 190 hp, but don't realy want to unless I have to. The dealer is telling me that the smaller engine will be fine, but I wanted to get other's opinions. We are going to use it for tubing, water skiing, etc. One of my kids is a big guy (6' 1", 250 lbs). Is the smaller engine going to be powerful enough for water skiing, etc.? Thanks for the help.
