Message: <blockquote data-quote="Bauer" data-source="post: 348212" data-attributes="member: 775">The Lund 186GL/200 merc combos should have come factory with a 19p Enertia or Tempest, with mine, I found a 18P Enertia to be about the best, I would have loved a 18P Tempest but they only go in odd sizes. I finally came to grips with the cadillac ride and the fact that it is a very heavy boat for only a 200hp max motor. You do have a few options though:1: Mercury props have a Performance Vent Plug (PVS) system, You can mix and match different size openings (or no plug at all) to increase your RPMs at take off. They have 4 sizes, solid (plugged), small, medium and large openings. The effect that these have is that they increase exhaust blow by on the prop blades creating the effect of light cavitation causing your RPMs to spool up faster. These have little to no effect on top end speed. You can use a small flat blade screwdriver to pop a plug out and see if that helps at all. Your dealer should have these on hand or certainly can order them for you if you find that it helps by removing one or two and you want to start playing with sizing. There is no harm in leaving a plug or two out. I do feel it creates better effect if the exhaust blow is the same across all blades (4 PVS plugs)2: Trim tabs will most definitely help with time-to-plane, they are also wonders on most other aspects of boat control as well. It is my belief that every boat should come with some sort of trim tab from factory. However, keep in mind, with tabs deployed, you are creating drag, so they do not help with top end speed, some people do think this! It is simply for ride control and wave entry/exit strategy.3: Demo props. Most dealers do allow you to demo props for a fee. For instance, North Country Marine in Garrison will let you demo a prop for I believe about $40. They will get a credit card number from you for the total price of the prop incase it is damaged etc, but only bill you for the rental fee if it is returned safely. The bad part about the supply chain right now is props can be hard to come by so its not known if the prop you are looking for is available or even part of a demo program. If you are doing prop testing, all props should be tested the same day in the same weather and load conditions to get a true comparison. A temperature change of 20 degrees between runs can create a huge difference in how your results check out, and believe it or not, flat calm is not the way to do it! You want the surface tension of the lake broken by a light chop. This creates less drag.Good luck!</blockquote>
