On page 75 of the Oct TBM, they talk about 2005 Merc carb's having an "enrichment system" that eliminates the choke plate.<br /><br />"Merc's 'Turn Key Starting' will be standard on all new carb'ed sterndrive and inboard engines."<br /><br />Goes on to say that it can be retrofitted on engines from '97 and newer.<br /><br />If that is the case, sign me up for the 5.7L carb engine vs. the 5.0L TBI having the same price.
