My boat has set for two years. I recently put new plugs in it and etc. It started up just fine, however it started to leak water between the lower unit and the engine (on the inside of the boat)and it was alot of water. I was afraid that the block was cracked, but there is a definate 1/2 inch gap where the water is coming from. I guess I will take it in to be fixed, but I am curious how this could happen. Any help appreciated.
