Well Ive got a DP-S that is leaking water into the boat. It is so hard to see down in there. I thought the leak was the seal where the Y pipe attaches. I pulled the motor and replaced the Y pipe seal. It is still leaking. My bellows are dry. I filled the boat up with water to just under the starter. It was not leaking out. So my leak is higher than that. Now looking at the IPB's I see the transom seal. I can not see any other seals in the IPB. Is there a seal at the water tube?Is there any other seal that you guys might think I should also order? Thanks for any advice
