2006 24 VE wont start

[ereed969]

I got the boat out last night for the first time in 2 years. Deep cleaned it last night. This morning put batteries in and hooked up fake a lake. It will turn over but will not start. Batteries seemed weak so hooked my truck up to the boat. Still wont fire. Anyone have any suggestions or could point me in the right direction. I believe its the 350 hp GM. I guess i can top off fuel maybe add some sea foam. Any help would be greatly appreciated. Thanks.

Start with the fire triangle: fuel, ignition or compression. Check fuel pressure while cranking (should be somewhere around 45psi), check spark using an inline spark checker and check compression. 1 of those will be your culprit and then you can walk that path. Also, check the kill switch is engaged.
