How to deternine jackplate setback size?

[Sivart]

I have a 92 model Evinrude XP200 on a 91 Astro Quickfire 19FS. The boat measures a little over 20 foot long. I plan on getting a jackplate but I really have no idea on how to pick the right set back size. I see 5,6,8 inch set backs and they go on and on. Can some one steer me in the right direction?<br />Thanks in advance.

I think I would be looking at a Bob's machine jackplate. The 5" model can be used at 5 or about 3, but I'm not sure that's enough on that long boat. I don't think you would go wrong at the 6-8" range.. I'm running a "Bob's" 5 with 2" spacers with the same engine on an 18ft alum, so it may need a bit more on yours, but each hull style is different.<br />Actually, Dhadley would be the best to answer this...

I'm not sure I'm the best one to answer but I'll try...<br /><br />A lot depends on your balance now. If you need more bow lift, get more setback. But like Kenny said, you can use the 2" spacers also. I have a 10" on my Dusky but its a tank. <br /><br />One good thing about it, if you get one and ever decide to sell it, it wont last a week.
