Slidemaster jackplate

[Bass Cat Boats]

This was posted on your High Speed driving post yesterday. You could tighten one side and bring the other up on some plates, though some will not bring it to flush. The offset is so minimal it will not be noticed. On later plates this is fractional and you would not notice it on the operation. In the early 2000s we have found some plates well out of square, and we were quite concerned At first this was a great concern to us, though after squaring the the plats and cross checking them, the mounting was well within square for the engine centering. In the 70s and 1980s BCB, and others, ran engines offset a couple of inches for high performance and race applications. You could be well off and no one would be able to tell and operating difference other than engine heights.

BCB – I am thinking about raising my plate on my Pro XS 175. I assume that you loosen the bolts on the two outside slides and adjust with the large bolt in the center??? I am going to mark or scribe the current setting so I can measure where I started as I move it upwards. I was told that 3/4 ” upward would make a big difference. Any ideas from your perspective?? Thanks

We only suggest 1/4″ increments in most cases. More than that is too much to raise one in one sitting without running it between loaded.

I suggest you scribe a refference mark and stamp an X next to it. Then scribe each setting that you try afterwards. 1/4″ increments is what I have always been told to try for adjustment, but you should check if somebody on Bass Boat Central has documented an optimum starting point for your boat & motor setup. Usually the starting point is a specific distance from the bottom of the pad to the center of the prop shaft with both level with the ground.

Thanks for the information guys. I will work in 1/4″ increments marking each as I progress. All input is much appreciated.

The key here is that the “sweet spot” is quite narrow. Typically 1/2″ or 3/4″ total. If you mark that 1/2-3/4″ “band” on the jack plate, going above or below that band will produce worse performance. If you move in 3/4″ increments, you can jump all the way over the sweet spot and never find it as the next jump will be too high or too low. Thats why the 1/4″ recommendation. The prop is about 14″ in diameter. The usable range is from somewhere about 0″ (propshaft even with the pad) to 4″ (propshaft 4″ below the pad”.) Non-racing hulls probably dont have that large a range. So the adjustment bounds are pretty narrow, giving just 17 unique “stopping points”. Going slow in moving up or down is a good thing.2008 Pantera Classic2014 Mercury Pro XS 200

Team C&O Marine sells themIts actually a backwash plate that fits up inside and mounts on using the two threaded holes on either side of the center adjustment bolt.http://www.teamcandomarine.com/catalog_ … word=HSP-8They sell all sizes to fit the SlideMaster. 8″ part number is HSP-86″ part number is HSP6Last edited by RazorCat on May 28th, 2014, 2:35 am, edited 1 time in total.

do they work?

Im ordering one in a few days. Had intended to last year and other things took priority. From what Ive read on BBC, they mainly prevent water from shooting up thru the jackplate and into the splash well when you come off plane. I know the front my Mercury on my Sabre FTD always has water spots on out after a trip. I usually come off plane and them bump the throttle just as it sits down to keep water off the back deck. I still get a little water coming up thru the jackplate. No biggie, but Im installing one anyway. From looking at the design I believe it will require periodic removal and cleaning if you fish lakes with grass, debris, etc., as it will get caught in there from time to time. Ive never really seen the need for a bottom mounted holeshot plate on the Slidemasters. The way theyre designed with the bottom curved up and out from the transom they dont seem to catch that much, if any, water when you come out of the hole.

I could be wrong but I thought someone on this board went to add one after they ordered it from C&O and it didnt fit correctly (I dont remember the reason). They had to return it and order it directly from R&R. Again, I may be confusing this with some other post so my apologies if I am.I however installed one on my previous bug boat for the side scan transducer (ended up installing the xducer in a diffferent place to get better pictures) and noticed a slight improvement in hole shot. Im not sure how it would affect the BCB. I would THINK if you are heavy in the rear with powerpoles and 4 batteries it sure wont hurt and may possibly help.Good luck and let us know how it works!

It simply adds a flat surface for the water to push UP against . — Aaaah , physics at work . — What a concept .

Make sure adjusting bolts are loose then give the motor a good shake. Motor should even it out. Trying to force it on a block only binds its. Let motor hang freely while adjusting it.2013 PANTERA 2MERCURY 200 PRO XSMINNKOTA 80LB FORTREX25 fury

Will try that tomm afternoon thanks Sent from my iPhone using Tapatalk

Never had that happen. Just make sure you loosen all 4 side bolts enough that the slides drop down. If it sticks, Id be thinking some sort of lube myself, but I have not seen this. Mine is almost 10 years old and it goes up and down easily, no hard pulling needed going back up at all.Your description would concern me a bit. The motor is bolted to each side plate with two heavy-duty bolts. I dont see how one side can go lower than the other if every bolt between motor and jack plate is tight. The motor would need to tilt left or right to let that happen I would think… I would certainly check those four motor to plate bolts. Something like 90-100 ft-lbs for those. And by all means, as redngoo suggests, do NOT try to support the motor while raising or lowering it. That big screw in the jack plate is something like a 10 pitch if I measured correctly (2.5 turns per 1/4″ of travel). Thats plenty of “oomph” to lift or lower that motor by itself…As far as “where was I?” I was apparently visiting hades this afternoon. Went down to the river, 95 degrees, 150% humidity, blue skies with nary a cloud to be found. If you saw the movie “space cowboys” where the centrifuge scene was playing out, to quote the flight director “I am getting too old for this crap.” Looking forward to October.Last edited by oldtimer57 on July 20th, 2017, 4:30 am, edited 1 time in total.2008 Pantera Classic2014 Mercury Pro XS 200
