Any Running a Jack Plate Here?

[Blu_Lunch]

Hello I have a 74 V-20 CC we bought last year with out a motor , the boat is in nice shape with a new tramson redone by a local marina 2 years ago. The local marina called the other day and one of the customers wanted to trade in a 83 Merc Black Max 150 for a new motor well to make the story short I grew up with the salesman and he had the motor checked out it was fine tons of new parts including a new lower unit 2 years ago rebuilt carbs last year and water pump, new starter I ended up matching what the dealer offered 700.00 and I bought it. The compression warm was 117-120 psi across all 6 cylinders and it fired up cold on 2 cranks. Here's the problem the motor is a 25 inch I need a 20 inch shaft the dealer said to just use a jackplate it would save a lot of money . Has anybody here ever use one. I like to hear about it ......Ted

Hey Blu...welcome to the board...we just had a Mako here the other day that was fitted w/a long-shaft motor on a jack-plate...looked like a great idea to me...the comment was made that you'd have to have a good, solid transom to make that work and sounds like you have that...I'd say go for it... ;) ;D...take pictures of the project and post them here...would be interesting...

[Blu_Lunch]

Thanks, I can't wait for it gets a little warmer{it's 18f today} so we can start working on it. It's a nice step up from the old Starcraft 18 ft tri-hull to this. We were stuck fisking the bays here for fluke and porgies . Now we can get out in to Long Island Sound and the race. This fall I be out salmon fishing at Lake Ontario .....I'll get a picture of the boat posted soon.....

blu, welcome, which side of the sound are you on,Conn. or L.I.? The older CC are beautiful

[Blu_Lunch]

I'm in Ct. I fish out of Waterford/Niantic I want to fish the rips off Plum Island for stripers and blues{no relation} The CC we have is still in decent shape a little elbow grease will have her looking good......

Blue - I've never run one, but I know that is a common fix for people in your situation. I'm headed out wednesday to pickup an older blackmax on craigslist . . . it's got a 20" shaft and I need a 25" :) I'll let you know what kind of shape it's in . . .

BTW - I love blackmax motors!!

Hey Blu...thanks for the pic!!...nice lookin' CC...looks like a LOTTA good feeshin' ahead!!... 8)...

Jack Plate shoukld be fine for what you want!!

Do I smell a trade on motors coming??

[bigshrimpin]

The lower units are interchangable on all blackmax motors. There were a few different gear ratios offered depending on the model.
1.87:1, 2:1. 1.78:1, etc. There are a few other parts that you need to swap aswell.

I think shipping is about $60, but you could always have them put in a 20" shaft too . . . that shouldn't cost too much.

Hey Blu, I fish the same waters, great area! I live on the North Fork of L.I..

[Blu_Lunch]

Ok, recommend a jack manufactor that will suit what I need....Ted

had one of those on a Checkmate 21' speedboat.With the jack plate down,WOT, trimmed out the boat only did about 50 MPH......w/ jack plate trimmed way up and motor trimmed way out it ran right around 70MPM.

Thanks guys. I picked up the motor yesterday. Next question, the motor came of a 19 foot Boston Whaler CC I was given 2 props with it, 17 pitch alunimium and a 19 pitch stainless steel prop, I have a feeling it's too much pitch for the boat , what are the 150 guys running. I took a few pictures of the motor before I took it from the other boat, I'll post a few tommorrow night. I guy I got it from bought a large 4 stroke Yammy I have close to 2500. in reciepts for work and parts on the Merc, it's clean......

[phester]

most guys w/ a 150 [myself included] run a 17" pitch.See what you tach out at, mercs run a little higher RPMs than average,I think you should be about 5800 WOT

My Merc 150 twists a 17p SS Vengence to 5550.

$700.00 for that motor???? Man, if that runs as good as it looks, you scored nicley. Good luck w/ it! It's gonna be just right on your boat.

[macojoe]

Yea but look he is using a hook to pick it up!!

What a wuss I and 4 Buddy's used man power like real men and put it on the boat!! ;D

Then after I had me hernia repaired I was good to go!!

[Blue_Runner]

After 4 rotator cuff surgerys on my rt. shoulder I'm not taking any chances...

[reelapeelin]

Good motor...thanks for the pics!!... 8) 8)...and great BUY on it... ;)...

Prop on mine is 3 blade 15 1/4'' dia. x 17 pitch...gets all there is to get from the motor... ;)...

[Blu_Lunch]

Next question {I'm like a little kid that NEVER stops asking questions} What are you getting for speed out of your 150's......

[bigshrimpin]

BLu - I just picked up the 1979 Mercury V200 today. It's been sitting in garage for the last 15 years . . . the thing looks brand new!!! Lower Unit is 20" has the typical paint skuffs. Let me know if you're interested in a swap? FYI - other parts that need to be swapped when you change from the 20 to 25" shaft are

shift shaft
mounting studs
water tube

I'll post some detailed photos.

Honestly I think the jack plate is your best option . . . I'm going to replace the shaft anyway with a 25" and I can send you the 20" shaft, shiftshaft,mounting studs, and water tube.

Blu, WOT @ 6 grand I'm toppin' out at about 42 mph on gps...that's trimmed all the way and light load...criusin' @ 4400 rpms gets me around 32 mph...I'm a happy cappy... 8)...

[Airslot]

I think I mirror Rap's #'s. I cruise 26-27 knots @7gph and WOT is about 39 knots.
When you convert to mph are numbers are similar.

I am looking at that right now :( How long did it take you to start doing stuff again after the op??
I hate to have it done now and screw me up for the summer!! I lost last year fishing it isn't going to happen this year!!
I was thinking of just having him shoot me up with shots for the summer and go for it in the fall???
But man does it hurt!! I have to eat Vicoden just to sleep.


O I have 175 Yamaha I tool around at 30 or so depending on the3 water and top out at near 40, I run a big prop to haul all my fish ;D so it slows me down a bit. 15 1/4 X 15

[Blu_Lunch]

The last op I was done in May2003 I didn't returned to work til January 04 it was at least 3 months doing nothing. Are having done open or thru the little slits? If you are having done thru the little slit it's not to bad ...open I had a 10 inch incision the first time and I was out of work for 1 1/2 years *I was so bad from a accident at work they had to cut everything and rotate my arm around 25 degrees *and put it back together...Good luck

[reelapeelin]

Yeah the things Drs can do these days...like my cousin, went in to have his heems removed, they got carried away and switched his mouth for his poop-chute...now he sits on his dinner-plate to eat and head in the crapper to poop...he's learned to live w/it after the settlement and all, but his breath will knock a bugger off a gut-bucket... ::)...

^..drinkin a beer must be a real pain in the azz too, huh :o

Gotta stand on his head... ;)...
