What battery do you guys recomend for a 88 js 550. The head has been milled down 40 thou. Putting out 150psi compression. The one that came with it is weak and old barely turns over motor. Thanks. I just bought this jet ski and am trying to get thing figured out.

Might be the starter and not the battery.Check the battery voltage when cranking it.It shouldnt drop to low
