We do a lot of skiing and the bow high on take off drives me nuts. I tried one of those one size fits all plastic hydrofoils, never did get it to fit my 2005 Merc 90 4 stroke correct, had to send it back. I use something else but I really hate to drill into the motor like most of them have you do. 2007 Dauntless 180-2007 Mercury Verado 150

I have not heard of any people adding trim tabs to a 170, in fact few add them to even the 18's You could try a different prop, what do you have on the boat now?

On that boat, I can't believe that by adjusting mounting height and prop you can't make it a fantastic ski boat. 2005 Merc 90hp 4 stroke, not sure of the prop or how high. It seems that most owners have the same issue. I use the boat for skiing and fishing. Hole shot power is not a problem, I'm just looking for something to knock down my planing speed. I read were a bunch of owners have installed a Dole Fin which works well. The only draw back to that is you must drill 4 holes in the lower unit which I'm trying to avoid. I did try the Stingray Hydrofoil, which is a non drill fit, however it does not fit my engine correct and I can not use it. 2007 Dauntless 180-2007 Mercury Verado 150

While I have never seen them installed on a 170 Montauk I have seen them on a 17 Montauk. The owner said he installed them to help with low speed cruising and planing as well as to help set the boat up for head seas navigation. I had a set of Lenco's on my 22 and loved them. Best thing I ever installed on the boat. Edited by Jeff on 07/14/08 - 7:35 AM 1993 23' Walkaround Whaler Drive

Member Posts: 202 Comments: 0 Joined: 06/02/07	I just realized how am I going to get to the wires behind the port side of the boat. The starboard side should not be a big deal, their is an access panel there. Any ideas? 2007 Dauntless 180-2007 Mercury Verado 150
