I have my 21' Maxum with a Mercruiser V8 stored on a trailer in a storage yard. I had it winterized in November and now want to fire it up. I want to bring it home and charge the batteries and then start it while hooked up to the hose to make sure everything functions prior to launching it. Has anyone started their boat out of the water after the winterization and if so how much smoke and for how long does it smoke once it's started? Or am I better off launching it after charging the batteries to muffle the smoke a little. Trying to be convenient while maintaining neighborly relations! LOL!
