Location: Mt. Zion, IL | The merc pro kicker efi motors are the same block if 9.9, 15, or 20 so the 15 will probably have minimal gains other than the output current over the 9.9.
I would opt for the merc as it has the highest current output of the kickers to keep gear charged. This means it could be used to start the main motor faster to get back sooner if needed which I value as a safety feature if my jump box also didn’t have the gusto to start my 300.
My 15 moves my 621 at 7.9 mph at WOT and about 5.5 at half. Power trim and electric start are musts in my book.it does have the pull start built in and is super easy to start, provided you remember to turn the key first (found that out playing around on the lake after about 10 pulls). If sticking with a tiller, the centering straps are very nice on the mercs. |
