trim tabs !!!
 

Thanks to everyone who answered on advise on props for my 25 tantrum. Hopefully I can find a used four blade
to start with. I was wondering if anyone knew what the difference is if the trim tabs are mounted above the bottom of the boat or even with the boat (seen both kinds). Just curious

i would go with flush mounted so you can run them level with the bottom and lengthen the hull so to speak.
without slowing down. you can still pull them all the way up to for max speed.

above...follow the instructions...mount them flush and drop speed...unless we are talking about arneson's??

parallel with the running surface or parallel with the bottom of the boat should be the question, or maybe it is???
