Question...
 

Anyone have a general idea of how much a 95' Yamaha 150 Ocean Runner long shaft is worth? Good running condition, good shape. I've been offered one for $2500, but I have no idea if that's a good or bad figure. :head:

I thought that only Johnson and Evinrude offered the Oceanrunner models.

condition is everything, but that seems kinda pricey to me. we are talking about a 16 year old motor that has been ran in salt water. i know yamaha's hold their value a little more, but a comp merc/omc can be had for $1200/$1500. if it is low hours and cherry, it might be the deal.

If it is a Johnson and I dont sell mine, I got one for you for $500.....I'll let you know.....it has low hours(600) and is a 25"

A nice 150hp 20" longshaft motors by Yamaha should be worth $2500 IMO especially if it is a 1995, probably originally came on a bass boat or fish and ski. Most Yamha 150's were 25" as the 2.6 liter is a heavy beast when compared to a Mercury 2.0 or 2.5 liter and the Eagle series v-6 OMC's. Most boats under 19' have a hard time carrying that weight. Like someone else said condition is everything. Yamaha V-6 XL or 25"motors typically sell for less as they are much more common.

Do ya see any crust around the motor and bracket?...checked the compression?...the shift shaft corroded?...foot oil clean?...clear w/no metal shavings...do controls come w/it?...SS prop?...if all the above checks out, I'd offer him 1800 for it and settle on 2250...

I am with reelapeelin $2000 would be a fair price if it meets the conditions he said. Ocean Runners are Johnsons, I personally would rather have a Yamaha (not meant to offend anyone).

Yes, it's a Johnson, in pretty nice condition. Compression is even and at 80psig +/- across all cylinders. But it's an opti and I've heard nothing but bad about them, so I passed. Since I bought the boat he offered it to me at $2000. I'm going to convert my 91' Merc 200 to a 25" shaft and hang that on the end. :head:

A Johnson opti ...no such animal opti would be a mercury. Guess it was a FICHT and if she is still running it would have had all the updates. The eagle series OMC ocean runners are great motors, ficht series have a lot of controversy.

I called it an Opti, not the dealer. He just told me it was an optical system, so I shortened it to opti. Didn't mean to imply that it was a Merc Opti. My mistake. In all cases it's a 150 and I want as 200 on the boat, so it's kind academic. It was a temptation since the boat is already all set up for it. Hopefully I don't wind up regretting my decision. :head: He did say it was not a FICHT, and it's not a looper.

I was gonna say, hold out for a 200 if ya can...comin' off a 225 and all...:clap:

Ok, lots of confusion here
Fist of all, it sounds like its a Johnrude Oceanrunner series with opical igniton. Pretty good motor, lighter than most. Its whats referred to as an Eagle Series. Its not as big or heavy as the 200/225 loopers. Bad part is parts are starting to dry up for them as Bombardier is starting to reduce inventory of older motor parts. Yamaha made s Saltwater Series and used carbs or the OX type fuel injection. I don't think this motor matches the details you've given. If the motor mentioned is a nice clean fresh water motor, then its worth that much at a premium.
As far as you going back merc, I've got a 5" extension and several 25" lower units laying around. Once I get this one boat:zip: in my yard finished, I may be able to free up some parts if you need.

I'm here for ya, Buddy!!...call me any time...I got a wrench I can bring...and a uh, screwdriver, too...:clap:

Actually, since I have time, I was sorta thinking about bringing it down to you and letting you do it. (ROAD TRIP!!!) Do I really need a 25" lower unit? Can't I just use the same lower end with the extension and a different drive shaft? What about the shift rod and the pick up tube?

Yes, The engine is a Johnson. Sorry for any confusion. It looks very much like my Merc though.. not the wide spread cowl of the 90* engines .. more like the narrow cowl of the 60* Mercs. ( I know the degrees are probably off, but you get the idea.. it's a narrow engine. Very nice looking. It's not a freshwater engine though.)

The engine you describe sounds like a 60 degree looper OMC which is like Spare said an optical ignition system engine. VERY good engines, and easily argueably the best engine OMC EVER turned out. They are also one TOUGH SOB. As for the extension on your MERC driveshaft, this is pretty unadviseable even from BAY who makes the adapter kits. It is ALWAYS best to go with a 25" lower unit with the spacer kit.

Do you know what the normal compression is on one of those engines? The dealer told me that this engine has 80-85 psi on all cylinders. I know that my 91 has 93-95 on all cylinders, but 80 sounds a bit low?

As to the Merc, I have no doubt as to the accuracy of your statement that it's advisable to go with a 25" lower unit with a spacer kit, but the engineer in me has to know why. Aren't the gears and such identical in the 20 and 25's, the only difference in them being the length of the drive shaft? What is it I'm missing? :head:

The compression on the 60 degree loopers should be up around 110-125 I believe, but it can vary from year to year depending on what style porting and pistons were put in it. The problem with using the 20" lower is the driveshaft extension you have to put onto the driveshaft of the 20" lower. They can get looose and cause vibrations over time is what I was told.

like ferm says, you want to avoid a 2 piece driveshaft if possible.

Personally I hate the look of a merc V-6 with the spacer plate , so much in fact that I often swap out the midsection. 25" clean mids are easier to come by than 20" and the look especially with twins just looks "right" to me.

Ok, that's what I was missing.. I thought that it would use a new 1 piece driveshaft, not an extension piece on the existing 20". Makes perfect sense to me now. No way would I want a 2 part driveshaft.. sounds like it's just asking for trouble that way.

Now, the question is, which way to go... Jackplate or extension?:head:

Merc uses two piece drive shafts on the service replacement lower units now, it may not sound great , but it works. There are a ton of used 25" lower around, 20's are hard to find. I've got a spacer on an older 2.0l, I'll see if I can get it off with out destroying it. I think I have a good 25" lower I'll trade you for a 20. Give me a little time on it, I still have this "other" boat in my back yard I've got to do something with

Sounds like a plan. :beer: I suspect that I'm going to find out where Goose Creek is sometime in my near future. :clap:

here you go welcome to goose creek
