It's a little older than you think - that's a 1979 model.

There is a latch just above and right of the front cover with the decal on it. Undo that and then kinda open the hood like a clamshell.

Nice motor (XR2/Magnum I model), stayed mechanically the same between 78 thru 85.

Based on Merc's 2.0 litre block that continued on the (primarily) the 135 horse and some 150 models (my favourite Merc V6 block).

Well built, great ignition on them, good carbs.

I would hang this motor off the back of my boat without a second thought.

It was on a 1985 Skeeter Starfire I recently purchased. Got it with intentions of putting the motor on my 1984 Suntracker 24' pontoon. Rated at 150. Currently has a nissan 70 on it. I think I could definitely pull a tube with the 150 on it. LOL

Any idea what the Merc weighs?

Graham,
On the Skeeter, this motor currently uses a dual cable steering system.
Would it be possible to adapt my singe cable system (currently on the pontoon) to steer this 150, or is that too much for a single cable to handle ?
Any advice on where to buy a longer control cable assembly ?

I read online about 8 pin and 14 pin control connections.
All I can find a a 4 or 5 pin connector at the transom, connecting to the motor.
What does all of this mean ??

That was a very early XR2 model and my "combined book" takes in all the motors upto 1985. It does show the oil injection system for that model, but I am not positive that it would have been standard on your particular model year or alternately, someone may have removed it.

If there is a tank under the hood, it may be still connected and funtioning, or disconnected and just sitting there. Because of that I would run 50:1 mixed gas until you are sure one way or the other.

You could get away with running a single cable system. I do on my 140 (Uflex helm with planetary gears), but at 150 horse you are pretty much at the max you would want to turn with a single cable.

Sooner or later you are going to need to replace the steering due to wear etc, so go with the single until it dies and then swap it out with a dual or hydraulic. (that's my plan - will go with a Baystar hydraulic when it needs to change).

And yes, should probably have an 8 pin connection for the controls - the smaller connection is most probably the trim/tilt harness. The socket for the main harness may be burried just inside the cowl - have a look when you get it off.

Graham,
Thanks for all the info..
I was unable to locate the 8 pin connector you talk about. However, in the cord harness that comes from the control box, there is a large rubber plug that on the other side, connects one cord to the motor, and one cord to the trim pump.
Is this the big connector you spoke of?
another question:
Is there a difference between tilt and trim, on my controls?
There's the obvious trim buttons on the shifter handle. But there is also a "trailer" button on the controls, which will raise the motor up all the way.
The "up" button on the shifter handle, won't operate anything...
how many solenoids control the complete "up down" functions?
Is the problem with the trim button likely just a bad connection of some sort inside the control box?
What are there wires for from the trim pump running to the motor? It's right near the steering cable connection to the motor..

Harold "Pro Series Tracker" was a fancy name to try and make a normal 40 sound cool. It was simply decal'd up for Tracker marine and sold on one of their package boats.

Personally, I like twin 40's, nice little motors.

The 40 was one of the many 2 stroke motors that were discontinued by Merc in 2005, but for now parts are still readily available from a Merc dealer and it's new enough that dealers will still service it.

As to a fair price - it's still fairly "new" by outboard standards, and a 40 is a desirable horsepower (still a strong market for them).

It would have originally sold for a little over 4K at a dealer (you can still buy a brand new 50 2 stroke for 5k).

The hours sound fair for 6 (almost 7 model years old). I like to see at least 50 hours a year minimum (tells me it was at least run and probably serviced) - so 300 or so hours would be fine at minimum (this is close).

If I was selling this I would be asking for about $2000. If I was buying I'm sure I could find one for $1500, so I would put the actual value in that range.

Many dealers won't take a carb/2s in trade now because they know their days are numbered by the EPA.

NADA pegs the value for this at $1280-1440, my numbers reflect my "local market", your area may be a little different.
