Cruising at 4000 rpm at Silverwood. Then with no warning, a loud KERPLUNK! Engine wouldn't turn over. Put a long screwdriver on the drive line to turn it but it would barely budge. I can hear parts rattling inside when i did that. Oil pressure was about 60 psi. I had just glanced at gauge before the KABOOM. Ranger towed me in. Much thanks to him! After I got the boat on the trailer he came back and to help me go to thr beach where all our beach crap was at. Fun day... I'll keep you posted on what I find.
