As I said, I need to give it more time. It'd be unfair to Perfect Pass for me to knock it based on one experience. There is nothing wrong with the Install or settings. I liked PP in my friends boat, so it maybe a personal adjustment time.
We were running in a small lake (about 1000ft straight-aways.) The turn-arounds are small hair-pin turns. We were fighting with Perfect Pass almost falling off of plane at the end of the turns - so we'd have to throttle it out of the corners, then PP would spend another 200 feet getting the speed corrected again. I could out drive PP in this situation because I can set the RPM exactly where I want by making radical throttle adjustments that PP can not. Plus, we were running heavy, ~2500lbs plus 9 people.
The Perfect Pass Manual suggests that it'll take 3 hours. The PP manual is kind of cheesy and isn't as thorough as it should be - especially with regards to late model boats. I suppose someone could do a half-a**ed install in less than 3 hours. If everything went perfect, I could install it in 1.5 hours. The reality is that, in the real world, you run into snags. My snags were finding the Speed wire and the RPM wire. You'd think the RPM wire would be fed right to the tach on an 04 Malibu. However, this is not the case, the Tach on an 04 Malibu is simply a read-out gage that is controlled by the ECU. The underside of the dash has about 100 different wires. The PP manual said to refer to the attached instructions for installing the paddle wheel - that's it -- no attached instructions. They neglected to provide information about what color of wire you should be looking for in a late model boat with an existing speed wheel. Malibu did leave the speed wire and tach wire stubbed out for future PP install. It took me 2 hours to find these wires as they were bundled so tightly in the wire harness and there were other wires that were stubbed out and lose. Late model Malibu's have some kind of HEI ignition with electronic advance - so with out a schematic, you can't find the tach wire on the engine. I don't have a fake lake, so I couldn't just fire-up the boat and test for RPM. I did this install solo, so I didn't have someone available to spin the paddle wheel to help find the speed wire. In the end, it's an easy 3 hour job, if you have two people, then you have to add in their time to. By spending 4 or 5 hours, my PP is perfectly installed with all the cables neatly routed as good as factory.
It'd be easy to estimate under 3 hours if you've never done it.
