I now have about 45 hours on my '04 Johnson (Suzuki) 140 4 stroke outboard. I've noticed that after running to a destination and then shutting the engine off for an hour or two or three, it will then produce a generous puff of blue smoke upon start up. (kind of a burnt oil smell).<br />The first service was done at 15 hours and then synthetic oil was used as instructed by the owner's manual. I am now wondering if this was too soon to go to synthetic oil. The dealer's mechanic has suggested that I go back to regular oil until the next oil change. Is Suzuki being unwise with their instruction to use synthetic at the 10-20 hr service?<br /><br />I would appreciate any & all input.
