The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
Sounds like some type of restriction. Is it used in salt water? It indicates some sort of blockage of the water not exiting and starts to boil inside head. You could have sucked in silt etc? You have to check water pump. Dont run it with this happening. You will ruin the motor. Good Luck!
