Author Topic:   MONTAUK: Auxiliary Motor Shaft Length

jeep guy posted 05-11-2009 10:30 PM ET (US)
With a transom-mounted [auxiliary motor with a 20-inch shaft length] on a Montauk, when using the main engine with the auxiliary engine [tilted] up, will [the gear case of the auxiliary engine] tend to drag in the water at times? I have read that some like to use a short shaft or 15-inch shaft with an adjustable bracket to get around this problem. I am new to boating and am researching an auxiliary for my 1970 16-footer. Thanks

I believe there was just a recent discussion on this exact topic.

Hmm--Couldn't find the discussion I was thinking of.
Here's the owner's manual recommedation:

Thanks for the article. I have been trying to search the threads. I found some discussion in reguards to the kickers. Contrary to the directions, it seems like most people mount them on the starboard side for steering purposes. Also i was looking for feed back from people who have the kicker with a 20" shaft, transome mounted as to whether the kicker drags at all. Also does a kicker interfere with pulling a tube or water skiing?
If anyone know of a thread for me to view please let me know.
Thanks

My 20" shafted Honda, hung directly on the transom sits high and dry when tilted up.
I've never pulled a tuber/skier with the kicker on the transom but it sits inboard of the eye I hook the bridle to and it could be a problem although I bet it could be worked around. I think a bracket being in the way also would be even more of a problem.
The conventional wisdom I've picked up on this forum is to put a long shaft directly on the transom.
My experience validates this wisdom. I originally had a 15" shafted Honda that worked OK in calm conditions but not so well in any kind of chop.

I have tried about four or five different 20" shaft kickers on my 16' and none of them drug through the water when tilted up and on plane. One was close but still not a problem.

I agree with these guys. I have owned several Montauks. A 20" kicker clamped directly to the transom will not drag at all and is the preferred method of mounting a kicker on a Montauk.
Port or Starboard, that is your choice.

I get a slight drag from my 20' kicker mounted on the port side of a Montauk. It doesn't appear to impact performance any but the only skier I pulled was the one that got too close to me while fishing.

I made the mistake of buying a 15" 6hp four stroke for my '79 Montauk. The four stroke is good for me because my main motor is oil & fuel injected so they both draw straight gas out of the same tank. The hp, weight, & noise is acceptable. I steer with my wheel because I have one of those gizmos that ties the two motors together with quick disconnects.
The 15" will work ok but if you move towards the bow it will suck air & that's bad. Also, on a windy day, it is easy to get blown off course. I assume because of the minimal prop bite. I am considering mounting an aux. bracket to get the prop deeper. Or, when my ship comes in I may get a 20" kicker. If I do, I will buy a 2 cylinder to keep the vibration down. I'm tired of picking up screws when I troll.

Thanks for all your replies. I did more searching on the site and found some good threads. It does seem like the standard is [20-inch shaft mounted] on the starboard side for torque reasons as as per [the Boston Whaler owner's manual recommendation].

Thanks again for all the answers and links! Was wondering if anyone else had experience/ or links to discussions with a kicker motor and water sking/tubing. Any issues? Want to fish and still tow the kids
Thanks
