I've got a "new" engine for my Montauk that I want to put on this winter(changing from a Mariner to an Evinrude). I've got all the bits and pieces (or will have soon) and am curious if anyone has hired this task out? With my time constraints and limited garage space I might try to find a dealer to make the swap. Anyone have ideas on the labor cost of such a swap? What kind of time to swap the engine and controls would be involved?

Thanks!

Should be a 3-4 hour job at the shop rate. Make sure you have the proper controls and cables, and your motor removed if you can that will save you $$$.

Last time I had it done was 1988. Back then it was $175 but I was shopping around for outboards last week and I was surprised when he quoted me the price to put the outboard on my boat. Don't remember the exact price but it
was several hundred $ - I'm thinking around $600. I just remember thinking that dealership won't be getting my business.

Read your warranty!!! It might specify that installation by a non-certified mechanic could void it. You could probably take legal action against this but how much would [b]that[/] cost you? Probably more than the $600 it cost me to have a mechanic install mine...

Being your changing from a Mariner [ merc controls ] to an Evinrude [ OMC Bomb controles ] it's gonna run you close to a grand easy for a binnacal [ $400 ] new cables, then the tech is going to remove your old engine & hang the new one, then he has to time the DFI & install a new oil tank & connect it & bleed it, install a new tach.
Your looking at 6 to $800 just for the labor alone at $95.00 per hour here in Calif.

Assuming "new" means "new to me" there is little to lose and much to gain by DIY. You didn't provide enough details for anyone to give advice beyond shop or dealer costs.

Sorry about that. Let me add some details...

The engine is a used 1990 Evinrude 90 I bought from a CW member. The existing Mariner runs great but doesn't have tilt/trim...hence, the change. I have sent the check for the OMC binnacle and gauges being sold by JohnO so I have that side covered.

My biggest concern is the time and the space to make the change and the equipment to do it. My 2 car garage is consumed by Porsche, miscellaneous furniture, and woodworking machinery/tools. I can't get the boat in there so it would have to be done outside.

Assuming the holes match properly, the process of changing the engine should go quickly except for the logisitics of making it happen. Maybe my concerns are worse than the reality of changing it over myself? With a rented cherry picker can I do this job by myself?

Thanks!

Hell yes! Your garage contents indicate patience, measure twice, and maybe tech skills. That pig (Porsche) alive or dead (runing or in restoration). P not a fool proof indicator. My neighbor has one. Not sure he could change his underwear w/o help.

Not big deal. Check spacing arrangement of bolt location in transom vs engine bracket but should find it ok. Don't over tighten the mount bolts (about 20/25 fp and no compression of the glecoat/fg). Use nylock nuts and seal transom with 3M 4200. Swap engine easy. Take your time on the controls.

Remember to install steer cable before mounting engine.

Frankly, t&t much overrated. Ran '66 OMC 100 w/o T&T on '66 Sakonnet for 35 years with bad back the whole time. Now have Montauk w '87 OMC 90 w t&t. Preferred manual. Faster and lasts forever. T&T motors are expensive.

Where are you located. What's the deal on the Mariner?

Bill I was able to mount my "new" Merc onto my Newport by renting engine puller from local rental center. It cost me about 30 buck for the day and lifted the Johnson off easily as it had a circle hook on the power head for this job. I had to borrow a lifting eye or hook from my Merc dealer which screwed into the power head to lift the Merc onto the boat. I then had my marina hook up the "new" motor (2001 Merc 75hp ).

They installed all new gauges including an hour meter which I am real happy to have. I also had them put on a fuel/water seperator. I supplied the Morse Binnacle MT2 controls.

It took a solid 8 hours. I had recieved quotes on an installed Merc from two other shops and all the labor estimates were 8 hours.


ps I am sending out your items Monday AM. I am sure the check will be here soon and I do not want to hold you up.

Good luck.

Thanks for all the replies!

This board really is phenomenal! Although John doesn't "know me from Adam" his offer is very gracious!

No hurry, however, since I won't have a free weekend for the next few weeks. John is an example of what makes this board great!

Gene, I live in Georgia. There is nothing wrong with the Mariner. It's the one that came on the 1984 Montauk I bought from Arch in August off of the Sales forum. It's a recently rebuilt 1980 model that runs fantastic. It doesn't have t/t...which I need for the kind of boating I do. Rather than retrofit a tilt/trim unit, I bought a 1990 Evinrude off the sales forum. (I've always been an OMC guy). So, the plan is change the engines, ebay the Mariner, and be ready for the spring!

BTW..Here's my Porsche (my mid-life crisis car!). It's a 1996 Carrera 4S.

How often do mounting holes not match up when re-powering? I read somewhere in here that they often do match. Seems like you'd end up with a weakened transom if you have to plug old holes and drill new ones.

I'll store the Porsche in my garage in Florida for the weekend, tell me when to come pick it up... *grin*

BTW: My garage is loaded with stuff to the point I can't fit my VW Corrado into it. However, if I had a Porsche like that coming for a visit, it would be a real incentive to toss a LOT of junk out! Ironically, if I had a P like that, I'd probably be parking it in the living room. After you fold the mirrors in, it will fit through a 6' sliding glass door... (German car mirrors fold in for shipping).

63 Model,
Not a bad job. Takes way longer to change rigging and wiring than to swap the engine. I have an eye hook in my ceiling, screwed into rafter, I use a come along and have swapped a couple using this method. Strip all the cables ect. off the old engine before you swing engine, have the new engine ready to install. Hang the new one and rig at your leisure. Mount the engine above the transom as recommended by CW board members.
You will also need a hand truck or some kind of cart to move the engines, I use an old coaster wagon the neighbor kids were throwing away.
Good experience and you know the job is done right.
By the way, where ya at in GA? I live south of Macon and could take the Porsche for a while,,,give you time to change the engine, get it broken in, wax boat, repack trailer bearings,chat with board members,install full canvas ect.

Believe it or not, lay the engine on an old chaise lounge cushion and slide it wherever you want to.....easily.
