Engine wont turn over. New battery, electronics work, blowers work, then I try to turn over and CLICK, everything goes off and nothing will work until i disconnect the battery, wait a few minutes and hook everything back up. Someone told me that it might be the starter engaging with a seized engine. Can someone give me a "how to" for turning over the engine manually? do i need a special tool? looks like a hexagonal shape in the middle of the pulley. do i need to remove spark plugs or anything else? i am just scared that its seized and would like to rule that out first before i go troubleshooting electrical issues... Any help would be greatly appreciated! haven't used the boat for 2 full seasons now so this is the first time trying in almost 3 years. Thank you!
