Hi all, first time here.
I have a 86 268DA with a 260/alpha,I recently took my boat out on the Detroit River and all was good for awhile. Towards the end of our outing, I was cruising along at 3200 rpms when I felt a "clunk" like I hit something. I was in 20ft of water and immediately backed off the throttle and every thing seemed ok. I checked the prop and not a scratch on it ( 4 hrs on new prop and hub kit). So I throttled up and got on plane and stared to go and I got the clunking sound. Took it back to the slip for the night. Next day I checked everything out and seemed ok. I checked the coupler, no rubber chunks or dust, I put a painted line on the coupler and input shaft for testing. I checked my gear engagement in forward and reverse, again seemed ok. I took it out and ran it WOT from dead stop several times for an hour and I couldn't get it to do it again. Paint marks are still aligned. I can't figure out for the life of me what happened. Like I said, it's got a 260/alpha1 with a 16x16 alum.prop. Anything guys?
