I have the twin 1503s NA.
Today, the wife and I were tearing it up on the lake (48-52 MPH). We went through some light debris and before much longer engine made a slightly funny noise that caused the RPMs to drop from 7k to 6800, but almost immediately returned. Went in to the marina, topped off some fuel, and as we were leaving the No Wake Zone, boat makes a horrendous noise out of idle, there was a heavy vibration and couldn't exceed out of idle.
Loaded up on trailer, no indication of obstruction when looking through the impeller cone. Both impellers look clear and no noticeable damage. What issue could I be having?
2nd issue - boat slightly fills with water while sitting. Bad carbon seal? Bilge it out fine, but just a pain to constantly remove.
