2001 200 efi serial# ot390682 rebuilt powerhead last year.when I go to crank the engine over after the initial start there is like there is no juice the first couple of tries then on the 3rd try it usually starts but barely, I had a similar issue last year so I replaced the battery and that seem to help. I took the boat out today and had it happen on 2 different occasions and once the boat was underway seemed to struggle getting on plane. Do we think it's a battery issue, a starter issue or something else thanks.
