Have an 2002 Yamaha 150 O/B. Just started using 3 weeks ago after sitting over Winter. Experiencing the following problem:<br /><br />Starts fine at launch, runs strong... let boat sit for a while after running for a while, starts up fine again.<br /><br />After running long period, shutting off and trying to re-start right away, hard to turn over, idles really rough and shuts off frequently. <br /><br />Yesterday, couldn't crank at end of day.<br /><br />I'm hearing potential Vapor Lock as mechanics just had in and cleaned carbs, etc... If experts out there agree with this potenial diagnosis, a) how do you confirm it b) how is it fixed?<br /><br />At mechanics now, love to provide them "free" advice, haha..<br /><br />thx
