will these be any good for my boat seem cheap
 

i don't think you can ever go wrong putting trim tabs on a boat. the price doesn't seem that great, but i don't know what they sell for locally in australia. this is the west marine link:

thanks for the reply might even go for new ones I have asked a few boaters about trim tabs most all said there rubbish but none have had any on a boat some guy said that if you have them set wrong in rough sea the boat will roll---seems like I cant find anyone here who has had them on a boat and if there that good why aren't people here using them---do they only work good on big boats ???? going to search around on utube see what I can find thanks:jet:

All I can tell you is, I have had boats with and without tabs. I definitely can tell you hands down, Trim tabs are great. I have them right now on my V20 and they have made a world of difference.
