off shore jack plates??? can they handle the pressure??? multi o/b usage? workable?
 

ive seen many inland applications, but..... hardly any off shore... can they handle the pressure/ racing/ pounding off shore.... ive seen one or 2 with multi engine brackets...

1.does it even make sense to use them... when you are off shore and inland in shallow water in ur boat??

2. I seen in an multi engine application where all the engines are raise at the same time.... makes sense.. or each engine has its own jack plate??

3. different types of jackplates for multi engine application....

thanks,....

I don't know much about this topic, but I do know this much. If I wanted to buy a jackplate, or talk with someone who would have answers I would call Bob's Machine Shop, the phone number: 855-JACKPLATE/813-247 -7040(per the ad). Bob's is in Tampa, FL. I have always heard good things about Bob's.

Here is the link to the website, I am eager to hear your findings and what others have to say. Here are the links to Bob's, I have them below, goodluck in your search

Hi!

I have a stainless marine gorilla jacplate on my 25 feet offshore Phantom hull. I have a verado 350 sci mounted on it.

I use the jackplate all way down for heavy seas. One inch up for cruise in calm water, and two and a half inch up for top speed. With the jackplate you can optimize the balance of the boat and the prop shaft height for any speed. You even save fuel using it!

A must to have for me. The gorilla jacplate is one of the strongest out there. No hesitation whatever wheater.

Cheeers, Toffen

Honestly it does not make sense to NOT use them. I dont recall ever seeing any outboard boat without them, they give a ctitical ability to infinitely tune a setup. I dont recall ever seeing one faill either.


are you referring to jack plates and brackets?

well... switching from I/o to outboards....
1. bracket needed....
2.. jus go with a bracket?
2.5 or with the porta bracket
3. if I just get the bracket, do I mount the engines on the jackplate on the bracket?
4. will it handle the big 350s < ( jackplate and bracket,
5. jus go with the porta bracket and make sense out of everything?

please help.... what are some of oso application and can u show me pics... and help me make things work...

What's it going on? I've got two 3 liters bolted directly to an Armstrong bracket. ( 1040 lbs ) I haven't run the boat much since I got it but did take it for a good piss pounding in 4 and 5 ' ers before I put it to bed for the winter. I'm curious about the jack plate durability too. Just getting back into outboards from I/o.

Last o.b. boat I had did have a jack plate but it was a 17' and never saw rough water.

Not even sure it would make a difference for me with my current boat.....

The person to call is Scott Porta, with Porta Products he uses his brackets on the back of his 32 Doug Wright Race boat

What size boat? Are you talking hydraulic or manual? How many engines?

I'm yet to own one yet (that's adjustable, whether manually or electric/hydraulic) that I haven't smashed!
Depends what your doing with them. If you run offshore but just cruise, they can last. Race or run extremely hard and it will probably fail.
Initially I needed adjustable to find correct running height for different props. Soon found a very small window in height adjustment that worked for everything. After breaking plates enough I made my own static setback (it runs quicker and actually corners harder with 10" setback) that just had 4 different hole positions. I then bolted it to transom with 3/4" bolts cause I was sick of breaking/bending 1/2" ones and used 15mm bolts for engine to setback, 2x at top and 1 at bottom on each side (merc bolt holes will take a 15mm ss bolt. You just need to be sure your jack plate or setback holes are perfect or they won't all line up).
Haven't tried the gorilla plate Toffen speaks of or seen it used, so it may be ok?

HI!

I have used three kind of jackplates during the years.

1999-2000: CMC jackplate in aluminium. PL-65. Did not hold up for more than one season. Engine Promax 300 SVS
2000-2006: CMC jackplate in stainless steel. offshore version. PL-65SS. Very strong. However, the hydraulic unit needed to be replaced after a couple of years. Engine Promax 300 SVS
2006-2011: I did not use jackplates since my 2 x Merc 2,5 EFI SS engines was mounted directly to the transom
2011- : Stainless Marine Gorilla Jackplate. Been top notch. Very strong. Verado 350 sci.

Cheeers, Toffen

I have R&R slidemaster 3" jackplates. Love the design and no problems yet. They were actually made for the verado. I dont trust high setback jackplates on offshore use. Maybe on lighter boats but for heavy offshore use....I don't trust them.

Some of the big offshore fishing cc's have used them for years. Most on euro transoms and I think I recall seeing them on brackets. Check at the hull truth bunch of big cc owners over there. I am pretty sure a guy with trip v8 Monties on a 34 scarab is using them.

PORTA PRODUCTS Steve Porta .The best one out there for twins or multi engine IMO. Had one on a 26-28 Thoroughbred-Velocity, with a pair of Evolution Marine 400hp V-8s. BAD ASS. Never had a problem, rigged the boat in 1993 ran it HARD didn't beat the boat, but ran it hard till sold in 2004. Still like new.

But Jim, in another thread you said it was a 42 Cig, then a 41 apache... please make up your mind.

""But Jim, in another thread you said it was a 42 Cig, then a 41 apache... please make up your mind.""

thanks for pointing it out....oso info enforcement ......

is it wrong to ask questions when u want knowledge ???
i guess i better make up my mind about what i want to kno rite......
dfomf

Not at all but in the other thread you said you already owned the 42. Seems it shrunk once you added water ;)...post some pics of said boat and im sure more than enough people will chime in and help.
secondly lots of people responded with your requests for hulls, papache has 3 available for you yet you just want to go on and on about it.

so... u tryna ask me if I even own a boat, then....with out askin

for trailer sizing ... I was told to say ... 42 cigarette..... but by no means., is it.....

ne ways..... the point of this whole thing is to find info about stuff that I may or maynot kno about.... what do you have to offer??? if its nothing.... do it to the best of ur abilities .... ( ' everyone cant be the middle finger, some of us have to be a pinky" )

nope im flat out asking, same as i did in the other thread you ignored. You asked for apache hulls, they were offered. You said you had a 42 cig with 400 gal gas tanks... now you have a 39... which is it?

i got a inflatable bed from walmart .... with tiger stripe sheets for sails...

happy

Yup ok jim... proved my point...

thanks for the info.. everyone.....

Hi Toffen
I would like to know , if you have tried other prop after the rev 4 (BRAVO 1 FS or Blades)
(I have a revenger 29 with 350 ver and Bob machine Jack plate 4")
Thanks for your answer

WTF did I just (attempt to) read? :hitfan:

Unfortunately the all to typical OSO BS...............

I use the Porta Bracket with my V8's on my race boat. I have had a single ,twin and triple V8's set up on Scott's brackets.

what you read was another incantation of a midwest person that likes to waste others time, with hypothetical what ifs to bait people into talking with him. he asked about numerous boats and claimed to already "own" one and when he got the answers for his questions, he would keep people going with more what ifs. when i questioned him for pics he obviously has none. Sorry if my "BS" saves you guys from wasting your time on giving answers or taking your time to type out good solid advice to someone that has no intent other than to waste your time.

I should have guessed it was the DARRwin Award Winner Rob.

All good, i rarely post much anymore but I do love to read. My boats wouldn't be anywhere near as cool as i like if guys on here didn't share stories on what works and failures.
