Cracked Trim Tab


I have/had a SE Sport 300 Trim Tab on my 60HP 2 Stroke...
(pic at

Yesterday, pulling boat out of water, I noticed it had a giant crack running through it - split right through.

There were no signs of hitting anything in the water, so am wondering if anyone can shed any light as to what mght cause it...

There were rubber washers on each screw, so I presume these were installed for dampening any vibrations... but I must admit previously I'd noticed these rubber washers weren't sitting very well, and probably not doing their job... if indeed their job is to dampen vibration... could the trim tab have sheared just from that?

They are quite expensive (ish) to replace, so I'm going to try and epoxy it back together and screw it back on -- the screw holes mean that two two parts will still sit together in the right place... and if it just falls apart, I'll then buy a new one...

Anyone had any experience with snapping trim tabs for no apparant reason?!

Probably manufacturer defect/material fatigue, if under warranty, contact the manufacturer. Better would be to instal plain metal same size washers and adjust tight.
