G'Day Boys,
I have a Yammy 60HP 4-Stoke ;D My prop has had a few dings in it for a little while, nothing too bad but enough to cause minor vibration while under way and also enough to bring my max revs down to say 5600RPM. I always intended on either getting the prop repaired of buying a new one but was in no real rush until i read something the other day about damaged props and the subsequent vibration causing further damage to the outboard. Whether its true or not i dont know but it was enough to make me pull my finger out and get the dings repaired (just under half the cost of new alum prop). When taking the prop off last night i noticed that the trim tab was gone. Now this must have come off on my last trip which was approx 3-4 weeks ago :'(. I am assuming that it was due to the minor vibration caused by the prop or water turbulance from the rough blades but cannot be certain. After noticing that it was gone i then had a very good explanation as to why i was struggling to keep her in a straight line when entering the Boyne River at low speed through less than 0.5M of water and a rushing outgoing tide. Has anybody else had this happen or know what else could have caused trim tab to have worked its way off?
Cheers
JD
