Need for speed..

Got my 92 Pulse 186 w/ 93 200 Merc Running 25P laser II prop out for the first time today.

Was a bit dissapointed with a top speed of 66 in chop 64 on flats...
Measured the prop shaft at 5.5" below the pad.

I have been reading a bunch of threads on set ups, and get the general
Idea of what I need to do.

I am curious what the difference is between a jack plate and a mount which
gives you set back, or are they combined together?

And where is good place to look for these parts?

Let the madness begin!!!!
 
A jackplate will give you vertical adjustability and setback. I have an 8" setback bracket mounted on the transom and then I have a 5.5" jackplate mounted to the setback bracket. You'll see and hear of all kinds of configurations. I've seen two jackplates mounted together. Some people have one single unit(ex. 5"-12" jackplate) while others like myself use the bracket and plate combo. They have manual and hydraulic versions of jackplates. You should probably be able to pick something here or at Scream and Fly. Find out what you'd like for setback and start shopping. I definitely think you'll want to go higher than your current 5.5" below pad. Search around here for setups on the Pulse. You'll get a wide variety.

Good Luck !
 
I am trailering the boat, does moving the weight from the back off the transom cause any damage while bouncing down the road?

Thanks for the help.
 
I would definitely get one of those transom savers(support bar that wedges between your lower unit and roller on the back of your trailer). Especially if you travel any distance. The further you setback the more leverage there is torquing on your transom.
 
New at this, not sure if it would be too far back for mine or not?

Was thinking along the lines of 6"?

Any input here would be appreciated...
 
heres my 2 cents, pay for a hyd. lift. You already have a good amount of horse power and if your not looking for that last "engine blowing" .5 mph I think 6" is a good amount.I would advise water pressure gauge if u don't have 1 and work on plugging top 2 inlets or get low water pickups of some kind. In my case I went way back and I boat in rougher water 90% of the time and all that did was to cause tramsom troubles. I vote for keeping it simple and resaleable.:surf:

Sounds like my train of thought..

I run in lake St. Clair and that gets plenty rough for a 186
Boat came equipped with a water pressure gauge which is coming in handy.

Do you know if there is a way to get the motor to trim up further while under power? It trims up about 1/2 way on the indicator then stops. Maybe that is right and I'm just a weeee bit crazy????
 
You shouldn't have to trim that much. If you get your motor up and back a bit you can start working on fine tuning it. When you get it right you should be running very little positive trim if any. And a 25 laser wi9ll not get you your top numbers but is a good all around prop. What kinda RPM'S are you turning?
 
Fiddy P, I now see your from Warren and boat up on St.Clair. Just last week for the first time I ran thru Harssens Island and up the St Clair River for few miles.Its really nice up that away, I will surely be back a couple more times before end of summer.

My home waters is down on the other end of the Detriot River,north side of Lake Erie.Its nice and its home.But I love the north side, So keep in eye out for a black red yellow starflight up your way.

Your trim gauge could need adjusting. Your trim buttom has a built automatic stop. It acts as a safety switch for you don't over trim.Its been a few yrs but just aline the gage sensor and trim button at the highest point and work down from there I belive, like I said its been yrs. A matter of fact I don't even have a trim gage its was replaced by the jack plate gage.I do all my trimming by the seat of my pants. And one day u will 2.

:cheers

I didn't find 6" setback jack plates to help the Checkmates I've set up. I did like my 10" HD RapidJack on the Pulsare/Promax, but judging by the trim angle at best top speed, that package needed more setback.

The ideal engine setback is when your setback/hull/prop combo allows the engine to be at or very near level trim, when you're at your best top speed. My Pulsare with the 2.5 Promax 225 still needed quite a bit of positive trim when I was at best top speed, hence the setup could have used more setback. I didn't bother going back any further though.
 
Good to know...
It turns 58/5900 in some chop.. Red starts at 6 on my gauge, is that true danger for a 200 Merc or a generic gauge setting?
 
Yeah, it is awesome up there....
Went out tonight after work, launched her just as the storm was rolling out.
Sun came out, perfect run.

Yeah my trim gauge is funky, at times it bounces around and gets stuck all out or down????
 
I'm all for the big set back and faster speeds, just fear what the damages may be????? having the motor back off that far?
Do you need to reinforce the transom or is it good? I do like jumping swells..
 
Theres a nice newer land & sea jack plate + 8" offset bracket over on screamandfly just lowerd to $400 bucks today.

Heres another reason u should install a jack plate. I was out a couple weeks ago and the toggle switch to raise & lower broke off. The motor was just about 2" lower than usual for optimum efficency.Due to the extra drag of that 2" it felt like I was dragging my A$$ thru the water and I also burned up axp. a 1/4 more gas than normal.So in the the long run it will pay for its self after a few seasons.
 
checkmates are built like tanks
I love 'em
I cut the transom to install thru hull exhaust on my I/O, and I bottomed out the holesaw because the transom was so thick
 
If u go with a big off set, don't wait to add extra suppport (I'm talking with experience here).I know your waters. u can have it powder coated to look nice.
