Jack Plate Mod for Pulse 170

[Rob B]

I've added a Jackplate to the pulse 170 similiar to JW's setup on his old pulse171. Here's a looky at the 200 HP mercury hanging off the back.

Sure brings back memories! Checkmate gave us JUST enough steering cable for 6" setback, and boy were those two cables tight!

Now close off those top gearcase intake holes, or add the scoops and jack that motor up!

P.S., my splashwell was never that dirty...

I was getting worried when i swung the motor back, those cables become taunt. The cl of the prop was at or just above the pad. I actually let it down a bit. I think i'll try scoops, not sure about plugging holes.Oh the splashwell that's the residue from buffing that black out, I haven't clean it yet.

I didnt have that lower unit, but I know my 4-hole XR6 lower unit would start to lose water pressure around that height. Yours will lose it sooner. It's most noticeable when you trim it out to get the bow high, so just keep your eye on the WP gauge and you'll be OK. I raised the motor until the pressure got erratic at WOT and best trim, then lowered it down until the pressure stayed strong.
I forgot, where did you get the temp and wp gauges?

I got my gauges from overton's $72.97 shipped. Here's the link:

I got the teleflex vector(28238 & 28239), they closely match what's on the dash now.

When i get the water pump issue straighten out, i'll take the boat out to adjust the JP. I'll start about 3.5" below the pad and work my way up.

That should be 1 Rocken fun boat, with a 200 and JP.I've been running with my steering cables that tight for almost 10 years now without any trouble. Its a little tuff but if the wife can drive all day then theres really no proplem.

Have fun with her.You might of seen this already. Thier about the same.

She will fly, i hoping w/ a setup similar to JW's i'll see 75 mph w/GPS. Merc you've got one nice boat. I like those colors. Yes i've seen that before.
I've also got the steering pretty tight as well. I had a bunch of slop before. it.

Btw where are you guys getting those tubes/covers to hide the cables that go to the motor? I like the clean look.

 

[merc245]

The clean look comes from black plastic wire covers from your local auto store and black plastic zip ties, pretty simple but gives a great look.

Today I purchase the scoops from a Mercury Dealer. They actually had them in stock. For those that are interested in the scoops, they're called "High Speed Water Pickup" part #17280A2. I'm hoping to install them tomorrow. Now that i've added water temp and pressure gauges, water pump, thermostats and a jack plate hopefully i can get a few runs this weekend and play w/ the setup. Here's what they look like not installed.

 

[JW]

Cool, thanks for the reminder and the pix! I'll probably be needing those for my 2.0 135 or future motors. I'm kinda looking for a 6" CMC used........................

 

[Rob B]

Anytime JW. I've learn alot from fellow members so i try to contribute when i can. When ordering those scoops give the Mercury Dealer the part #. Otherwise they don't have a clue what you're talking about. Here's what the scoops look like installed on the LU.

Looking good. I looked for a set of those for my lower unit. They don't make them for the older ones. I have a removable plastic insert, not the cast in holes.

Thanks! 175 could you make a set for your motor from aluminum plate?

I am planning on testing with the stock lower unit. I know what it ran before before the pad install. After I get the baseline I will plug the top 2 holes and go up a bit more. The final test will be the installation of the bob's nose cone and low water pick up. Then test again.
