Newer Evinrude on Older Montauk

I just purchased a 1999 Evinrude (Suzuki) 4-stroke 70-HP motor. I am planning to install it on my 1986 Montauk. What prop would you suggest? It came with a 13 1/4x17 and a 14x17. What throttle and gear control do you suggest? What lenght cable? Should I mount the motor all of the way down onto the transom? Thank you.

I have always liked a "loop" at the engine for the control cables on OMC engines. I have used 20' cables on several Montauks to achieve this loop which does not allow the cable to bind in either direction and the loop is out of the way (not in the cockpit) more then any other installation that I have ever seen.
I have also like OMC Binnacle mount controls with Trim & Tilt in the handle...
Here is a link to photos of the loop above that I talk about.
The photo also show the circa 1986 Binnacle control with Trim & Tilt in the handle...

[Changed TOPIC--was "-Evinrude(Suzuki) 4 stroke 70 H.P what prop and throttle control"--jimh.]
I'd make some test runs with the propellers you have on hand. Report the speed of the boat and the crankshaft at wide open throttle. Use an accurate GPS to get the boat speed and an accurate tachometer to get the crankcase speed.
Find an accurate source for information on the lower unit gear ratio.
Post your results in a follow up message appended to this thread, and I think you'll get plenty of advice.
There are also many articles which provide information on your set up as experienced by others. You can search for these topics using the http://continuouswave.com/ht-dig/ search engine.
If you need new controls, you might consider the classic "Morse" style. I have seen some photographs of these on a Montauk style console and they look great. Installing them is probably a bit more complicated that just using the factory OEM top-mount controls.
I don't recall any recommendations to mount the motor at the lowest height on the transom. The general wisdom seems to focus on mounting the motor up one hole position.

Royce, I think Bigshot has the exact set-up you describe. Try to e-mail him: he's never been shy.

I already replyed to his e-mail but to read this thread I may ad.....I had the factory 14x17 alum and I will say it is .....ok. The 13 3/8 x 17 Stainless if double cupped is better but making it an 18" will be great. The 13 1/4 x17 alum will spin that 6000 easy, you need 56-5800 wot. Do NOT mount that low. 4 stroke Suzukis like to run high, go at least 1.5-2" above transom no matter what the mechanic says or how dumb it looks.
PS get a $150 jackplate and play with it along with 18' cables. I have stock OMC controls with the alarms etc. If you run an aftermarket, make sure alarms are installed and get the idiot light tach combo.

Thank you all- I have copied this posting as well as Nicks email. I'll post when I get it in the water.

hope mine looks that good someday. Can you buy paint and new stickers for a 70HP Evenrude.

What 18' cable are you talking about???
I have shown photos on the post above of 20' control cables and a 17' Steering cable... Do you have any photos to show us??? I have never seen control cables of any shorter length then 20' that were not in the way of some kind, or binding in some way, in a Montauk and an OMC engine mounted directly on the transom..
Please enlighten us with some photos so we can see the difference....
I know your engine is set back and that may make a difference but photos would certainly help... "A picture is worth a thousand words".....
I have seen cables stretched out in all directions, binding in every turn, people tripping over them, people getting their fishing rods, clothes, or whatever caught up in them.... What does your control cable installation look like as compared to the photos I show??? I did not invent the method I am showing. I am only passing on what many Evinrude/Johnson (OMC) dealers have suggested, and have performed in their own installations in the past....
Please let us know.....

Yikes! I posted the wrong URI to the search. I must be getting senile:

I believe my steering and control cables are 18' I believe. I will double check if I can. reason being I have all my cables running through the tunnel then into a big black tube to the engine. The tube is the same tube they use on Bracket installations and is VERY neat. I think the tubing is $3/ft and I used like 5' or so. The only wiring you see in my boat is the bilge pump and stern light. I can send a pic to someone if they know how to put it on their site or whatever and leave a link here.

I have seen a photo of Nick's boat at boatoberfest but the photo really does not show how the cables are routed and how much of the footwell that they take up. I think there is too much Beer in the way..
I haven't been able to find any other photos of Nick's installallation. Nick, if you can, please send me some photos of your installation.

Royce, don't take this personally, but I hate you. I missed that engine by 4 hours! Steve was kind enough to put me second in line, but it looks like you came through. Darn! Seriously, enjoy my engine ;-).

If you want to spring for a new Suzuki DF70, there is a dealer in NC who has many leftover 2002. Contact: John Mckenna, Walsh Marine, (252)447-2277. I am not endorsing him but he claims to be the biggest dealer in the US. Price-- you may be able to get one for about $5k.

Launcha: Thanks for the tip, I'll check it out!

Perhaps you can post your results elsewhere since there seems to be quite an interest in these, me included.

Eds had the 2003 Johnson 4-stroke EFI, (which I believe is the Suzuki/Evinrude 70hp 4-stroke with a Johnson hood and wiring harness) for $5,399.00. When I asked for a shipping price, it was $5,599.00, $6049.00 shipped to California. They have since changed the website to reflect the additional $200.00 they quoted earlier.
