Ranger / GT-150 setup advise

[Duck Loads]

Good morning,<br /><br />I recently bought a 1989 Ranger 375V with Johnson GT150 and would like some advise on the proper outboard-to-hull setup. <br /><br />This is what I know:<br />Prop, 14-1/2 x 24 raker.<br />4800 rpm @ 54 mph (speedo) with two people and 1/4 tank of fuel. <br />The GT-150 is mounted straight to the transom as low as it will go.<br />Distance from bottom of hull to centerline of gear hub is about 7".<br />Distance from bottom of hull to cavitation plate is about 1-1/2"<br /><br />I am looking for a set up to do two things. <br />Fishing by myself and taking the family out to ski. I know. The two extremes.<br /><br />I guess I need some recommendations on jack plates, engine mounting heights, and prop selection.<br /><br />Thanks a bunch,<br />Chris Hollis

Hello duckloads,<br />I have a similar set up to yours. 89 371V 150 XP Evinrude. My mechanic told me that a jackplate on a ranger boat with anything less than a 200 or 225 is a waste of money. Something about the boat being to heavy, they are built to handle rough water, not speed along! Who knows,I figure he knows more than I, I go fast enough already. I can only turn out 52@5300 rpm. This is just me in the boat with 1/4 tank of gas.... Might be waterlogged.... Good luck and this is just my opinion... People will share more! <br />Oshi

You didnt mention you top rpm (lets hope its not 4800!!) but that will tell a lot about the set up. The Raker could definately run higher. The 24 is a fairly decent prop so if you are short of your target rpm (5800 - 6000) some increased X dimension should help. <br /><br />Unless the hull has a lot of hook a jackplate should help. I would call Bob at Bob's Machine in Ruskin, FL since most Rangers nowdays come with his plates anyway. Call him at 800-966-3493. Tell him I said hello.<br /><br />Good luck!

That's all she'll do. 4700-4800 rpm WOT, WFO, etc.

Thats putting quite a strain on it at all throttle settings. Are you sure its hitting on all 6?<br /><br />Good luck!

Duck Loads<br /><br />Here is a great Ranger owners site where you can get info from owners with the same or similar set-ups.You can also review set-ups in the owners lists.I believe a 6 inch setback is fairly common on that size Ranger with the motor lifted about 2 inches off the transom..<br /> http://pub186.ezboard.com/fbbcboardfrm24
