I just got a boat (08 Tahoe Q5i) with 4.3 merc and it was sitting outside, had some sitting water in it (6 inches or so). Got it all cleaned and now it wont start. No crank but it has power

Mechanic's Assistant: Sometimes boat issues seem like they'll be really complicated, but end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Is there anything else important you think the Marine Mechanic should know?

Did the starter go under water?

It's possible. I'm not sure
Marine Mechanic: Tan, MerCruiser Certified Technician replied 6 months ago

Ok, locate the large terminal on the starter where the battery cable connects to the starter. Now with a jumper wire jump from the inside terminal with the yellow/red wire to the battery connection on the starter. Does engine crank?
