OK, now that I'm just about convinced that I should repower with a new engine on my '77 Montauk, I will probably go whole hog and get a setback bracket to increase space in the boat and aid performance. My battery is in the stern, and I have a 28 gallon Tempo tank under my RPS. I have looked at the Stainless Marine brackets - they have 6", 9" and 12" mini setback brackets. Is 12" too far back? 9"? 6"?

I've read the reference section and looked at the Cetacea pictures, but I still don't have a good idea of how much setback is optimal for a 16'7" hull. Any suggestions?

Thanks in advance.
John

Hi, John.

You have Email. I sent you a pic of the 4" setback fixed plate that mounts my DF70 on Sunshine III ('80 Montauk).

John:

Here are some pictures of my Montauk setup. It is a CMC manual jackplate with 4" setback.

I can't get those links to come up.

How do you like that CMC bracket? Do you have any before and after performance figures?

The links seem to be working for me.

I love the manual bracket. It is by far the best thing I have changed/improved on my boat.

(Light load, 1989 90HP Evinrude)

Before: WOT - 38.5* @ 5100
After: WOT - 43.8* @ 5600
cruise - 31.1 mph @ 4000 rpm
*GPS mph

Another additional benefit is the attitude of the bow after installation. The bow seems to ride slightly higher under power. This results in a much softer ride in choppy conditions.

Do a search on E-Bay under Jack plate or jackplate. Usually some good deals on new ones. I got mine which is a 6" setback and a 5" lift for $135. Main thing with setback is how much do you want to change? With a 4-6" setback steering cable and throttle/shift cables should still fit(mine did). With a 9 or a 12" you will probably need to change the steering cable at least. The only drawback to the bracket is reversing. If you give it too much gas it spits the water up the bracket and inside the boat instead of under the boat.

Bigshot: My Teleflex is shot (well, it works as well as ever, but the casing is cracked and rust drips from it), so I'm changing it with the repower - so no concern there. Same thing with the wiring harness. Thanks for the heads up about E-Bay (BTW, "jackplate" picks up guitar parts, but "Jack plate" gets you to boat parts - and plates with pictures of Jack Russell Terriers on them) - there are some good deals there.

Wild Turkey: What size prop are you running?

Thanks for all the responses!

Wiring harness should be fine(length wise) being they come in like 4' increments. There is probably a wad of it somewhere under the dash that you can get some extra length from. Battery cables may be a bitch if bat is under console. They are not cheap to replace. If you link 2 cables together, it will screw up inside the tunnel over time no matter what you do....I know.

I am running a stainless steel Michigan Rapture 19 pitch prop.

The second link above doesn't seem to work, I'll try again:

If you need to replace battery cables look at a good pair of jumper cables. Many times the price is more than half cheaper for a higher quality cable and the two are bonded instead of seperate cables.
