    521 Ranger with 10" Bob's Sits low, add floatation?

 I have a 2005 ranger 521 with 250HPDI. I installed 10" Bobs hydraulic and 36 volt t. motor and 4 bank charger. The boat sits very low in the rear now. I have read a few articles on people stuffing basket balls, beach balls, swim noodles, boat bumpers and other misc. crap in there to help. The problem I see is these are people with manual jack plates, as mine is hyd. I am worried such items would interfere with the movement of the plate. Any suggestions or ideas or previous experiences would be helpful.

a couple of inflateable blow up gals from the local adult store. Then if the fish aren't biting.......... This isn't a serious post is it? If it is, you should have called Ranger and asked them.

I guess if you added a lot of weight back there, it might sit lower.

You could probably figure out some flotation within your jackplate that would not be harmed or fall out when you adjusted.

So what exactly bothers you? Are you having a holeshot problem? Usually people who stuff their jackplate are trying to solve a takeoff problem.

Your other choice is to install some trim tabs. The commercial kind are usually hydraulic or electric tabs, mounted left and right.

Alternatively, some people (like me) have a center trim (mine is actuated by the outboard position.

Here's pictures of the one I made...

e people run a piece of metal straight back to guide the water smoothly past the bottom of the jackplate area. Here's an example:

kon we posted a bunch of pictures about this maybe 2 years ago.

The cheapest thing you could try first is the flotation. Cram something/anything up there and see if it helps. If it doesn't help, then if won't matter if cycling the jackplate hurts it.

   I would think you are referring to the boat when not in motion. from Mike I.  2/19/2012 7:24:34 AM
First you must remember you most likely "opted" for the 36 v TM meaning an extra 65 lbs. at least at the very back of the boat. The big offender here is the big yammi hanging off a 10"
plate. It's kind of like the big guy on a seesaw...the further you go out the more weigh in theory because of the fulcrum effect.I don't think that Ranger recommends a 10" plate. As far a stuffing the cavity with flotation I think that is only to help the hole shot.

Instead of stuffing with flotation, add a "hole shot plate". T-h marine makes one for their altas jackplate. I have been looking but no one makes it for a Bobs. It would be easy to fabricate your own. Just a flat plate of aluminum made the width and length of your jackplate. Drill holes into the bottom edge of the jackplate along the sides and screw it on the bottom. Add about 1" to the length and bend the end down at a 45 degree angle and it will function as a simple trim tab.

   Wait. What's the problem, exactly? from StevieP  2/20/2012 12:57:13 PM
So what if the back of the boat sits low?

Is it causing any actual problem? i.e. is the front end now so high that your TM prop is out of the water or something?

I could see adding the holeshot plate or floatation if the jackplate was scooping up water & thereby had a negative impact on your holeshot.

But if the only complaint is that the boat sits low in the back while at rest, I don't see the problem with that in & of itself...

   Jack Plate from Glen  2/20/2012 6:07:22 PM
I had a 04 Ranger VX521 with the same motor that you have.The difference is that I had a 6 inch Bob's with a hole shot plate instead of a 10 plate. Like the gentleman stated Ranger may not recommend at 10 inch plate for that rig. As far as a hole shot plate, I have one on my Bob's now & it came with my jack plate. I don't know if a hole shot plate will help your problem as far as sitting low in the rear or not. I would guess not. I'm like this if its not causing any problem with the operation of the rig, why bother. Good Luck - Glenn

Put tin the local truck scales and weigh the rig.
