I'm lucky enough to have both my Sj and Blaster stored inside and I start them both everyday when I walk by them to and from work ,That is the best thing for them is to start them everyday it keeps the fuel in the lines and you don't need a primer then .
if you have them setup properly and start them all the time then you don't need a primer but I have them none the less just incase a little water ingestion happens out in the surf or you need to start on shore after a little water intake or if you don't start your boat everyday like I do .
If you don't have them the best choke you can do is cover the entire air intake with your hand and your boat will start in a couple of seconds versus the pull the choke method ,Another reason to have stock air intake and not some fancy looking ones that give no performance improvement but just look cool .
Sorry rant over :banghead:
