I've read posts that say that the 250XS is the choice for the Pulsare 2100. The rationale seems to be that the boat chine walks after about 75 mph and becomes difficult to handle up into the 80s. I think the 250 and 300 weigh the same, but the 300 does require the higher octane fuel. If fuel availability is not an issue, wouldn't it make sense to have the 300 over the 250 so that you have the extra grunt if carrying more people and the challenge to go deeper on the speedo if you want? Regardless of the engine, you're gonna have handling issues over 75. Am I missing something else?
