I have a 2013 Z-7 Nitro with a mercury 150hp 2 stroke 23p tempest on a 6" jackplate with 2 10' talons attached. Question is does anyone have a similar setup, if so what speeds are you reaching. I'm currently reaching 51-53mph with tournament load a full tank and my son.ive seen some posts that guys are reaching 60+ mph. Was wondering if changing to a 6" hydraulic jackplate would make any difference for me?
No one is getting that speed out of an underpowered Z7. What you are getting is about right with your load and motor that small on it.
150hp is max rating on nameplate so how is it underpowered? The guys I've heard saying they are reaching 60+ don't have the talons, so I would expect to see them reach higher speeds. My main question is would a hydraulic jackplate help with my situation?
The 150hp setups are very sensitive to weight. I used to be a 60 mph boat untill I installed 1 talon and lost 3 mph. Sounds about right for your tourney loaded setup. Loose some weight and your speeds will go up. Also your jackplate, weather fully loaded or not will require different settings for optimal performance.
Don't pay any attention to PatriotAW4. He's one of those types that thinks he knows everything but don't know shit.Quote:

Now my boat had no talons and Phoenix runs a 10inch jackplate or setback plate on its 18ft class boats which like yours is closer to 19ft.
Couple of things I'd try to get a benchmark. Go alone, no water in livewells and 1/2 tank of gas and see how much speed you pick up. This will indicate how sensitive your boat/prop is to load. I'd also look at your prop to pad measurements. I'd post your reading in the nitro forum for feedback. Potentially you are not set up well.
I have the electric jackplate on current and last boat. I use it for skinny florida water. I've not found it is a performance making god if the boat manual plate was reasonably set. It is a mile or 2 of top speed not 10mph.
