Well ran out to the lake today to check on the Mark 4 I installed at 2 AM this morning to make sure she worked. The boat came with the X-4 pro and I used the same transducer and wanted to verify proper operation. The Mark 4 has built in GPS which I use for the speedo, bank beater not needing much in the depth dept. This will allow me to remove the speedometer and install something like the PRV-15 head unit for some tunes. Took some shots while I wasDSCN0221.jpgDSCN0222.jpgDSCN0224.jpgDSCN0225.jpgDSCN0226.jpg out.

With me alone, 265#, and half a tank with the 19" BRP aluminum at 51-5200 rpm hit a new high 47.2 gps.

Your engine is still very new with low hours. It will loosen up and run better. Should wind a little tighter after the first 20-30 hours.

You need to look into getting a different prop and/or raising your motor up on the transom. Should be running 5500-6000 rpm's.

I had a 17" Power Tech prop which I didn't like so I sold it, it turned 5700 but was slow only could muster 43.5. In the market for a 18" Raker, hopefully will have full funding by end of month. It was unseasonably cool that morning at 51, plus a good chop and little tail wind but it was moving so I marked it...

Wonder if your tach is off a little. With the 2.0:1 gearcase and a 19p prop your theoretical speed at 5200 rpm is 46.7 mph. And thats with 0% prop slip. To get 47 with that prop you would have to be turning at least 5500 rpm.

Possible I assume, factory tach, also want to get the I command tach which gets the info straight from the EMM as well as other readings like engine hours etc, like your Merc monitor. At $364 just for the unit the prop is first on the list, I command next, who knows maybe, just maybe by then I will be ready for your personal favorite.......JP but as of now I'm still on the fence, and I have the wife to contend with, she thinks she knows something.

That will be really nice. Nothing like getting that vital info straight from the computer. Factory tachs being a little off is very common. Mine is off 150 rpm compared to smartcraft. I would personally recommend getting the command link first. The more accurate info you have the better you will be able to dial everything in for selecting the right prop.

N2k engine engine harness will display the following: MPG, Engine Temp, Tach, Fuel with lot more options. All great data. Actually, you would need I-Command if you had a Lowrance HDS Unit. Also, N2k Engine harness and N2k Starer kit cost combined $130 but if you have a HDS unit you would not need I-Command gauge.
