Hooker Setup

Randy I own a 1988 Hooker with a 1989 150xr4 Merc. I would like to know what my top r.p.m. should be. It has a high five prop and a jack plate. I am new to all of this and would like to learn slowly and correctly. Please forgive me if I don't know the tech lingo. Also what should be the top speed? Is this a proper set up for this boat?  Thanks for your input.

Jed, 

Ah, the Hooker. This boat brings back memories. It being a 1988, I am guessing it is a stage 0, or stage 1. As we did not get to stage 2, 3 or 4 until late 1989. Unfortunately, the XR4 had a very small gearcase. Of all the motors, this one had the most difficulty with the Hooker because the boat was fairly heavy and had a 24 1/2 inch transom height. I got several to run 70 mph or so, but it took one of two things to do it. One being to run an ultra long setback of 14 + inches and position the prop shaft 3 -3 1/2 inches below the pad. The second fix was to convert the motor to a 25 inch shaft. With the increased leverage and propeller depth, we could run a very short setback of 6 or less inches. Without one of these 2 things, most of the XR4's would be limited to sub-60 mph speeds. When Howard built this boat, he did not take into account the weight of trolling motors, livewells and all the heavy tackle that most fisherman carry. The high transom height and short setback that was built into the boat was not adequate to carry all this weight. For now with what you have, run the motor as deep as you can get it to try to get that propeller to bite and pick the nose up when you trim out. I think you will find most Hookers that I have seen always seem to have the motor way too high and most of the gear in the boat too far forward. Hope this answers most of your questions. Let me know if any of this helped make the boat a little better.
