Have you guys used these?

I have one on my 90 hp Merc and never really noticed any change in getting on plain sooner..

BUT, I bought a new 15hp for my 14ft river rat boat and I'm having trouble getting it up on plane with just me in the stern. If I have someone in the front, or and extra 100 pounds of junk, I plane out just fine.

I'm thinking about putting one on this small motor....will it help?

I had one on my old boat that had a 25 horse. I don't recall anything significant that stands out weather it was worth it or not!!!!!

When by yourself have you tried setting the motor trim all the way in on the last trim hole?

I saw tests on those in Walleye/Boats mag tech tests...said they created significant drag on smaller engines. A lot depends on hull and weight disbursement. (As you already know)
Thats what determines how soon yer boat planes out under power....

I have one on my 40, using that and the trim really helps plane out the boat...  and I have a hand tiller set up...

I have had them on a few boats.  Usually to remedy too small of a motor.  I do think they help.  Still have to gun it to get some water flowing to make it work.  Then you can back off once you are up on plane.

We had 1 on an old glass boat that only had a 35HP on it, couldn't really tell that it helped or not IMO.

I just went back to read some tech columns and reviews on this.....seems they feel it DOES provide a boost and helps. I stand corrected!  Also info on finding ones that attach without drilling thru yer plate, there's a few that have tight holding lockdown clips that stated work well.....

The one you posted is to big for my motor Rebbs....but, they do have smaller ones available.
I REALLY don't want to drill holes in my new motor, but already bought one that requires holes (it has not been delivered yet)

I think I'll buy one of these first (they're not that expensive) and if it don't work...then I'll drill holes.

Thanks for finding it Reb!

Ah, I didn't do anything! Hope it works for ya!

Some boats benefit from a wedge on the transom to give a little more negative trim for starting out.   Of course that is for boats with power trim mostly.
