Ok Whats the big deal on what year a motor is read on....

[Steve135]

First don't bite off my head yet! My motor says its a 1981 Johnson but the swage plug on the block says its a 1988 Evinrude but if you look at the electrics on it its clearly a 1981 model? Now I have just replaced the 1988?? with a 1982 Johnson (thats whats on the block) but if you look at the electrics its clearly a newer model if you check out part numbers on components its a 1986. So My question is where can I find a list of part numbers for items like the rectifier/regulator that I can use with this motor? This 1982 model has a water cooled rec/reg(that it didn't come with)and I belive it to be bad, (eratic tach and no charge) Can I use the seperate rectifier regulaor combo from the 1981 motor?? And while I'm at it how can I check part numbers I have bunches of parts that I don't know what they came off of but have the part numbers?<br />steve

Check out iShopMarine.com They have complete part breakdowns by model & year incl part numbers

Lots of swapping around of parts going on. It's ealily explained. A power head goes bad, so someone buys an engine and swaps powerheads. <br /><br />It gets even worse with older outboards. Sometimes there's little left of the original, with parts from several different years on the thing.<br /><br />It can be a dilemma, so you have to check part numbers, when possible, before ordering new parts.

Once again you guys don't read whats written. Of coarse I know why it happens, I am the guy doing it. But what about a parts cross referance from differnt years.I just keep reading post asking for the year and nothing else is ever asked if there has been a swap out of parts, info is being giving based on a engine being whole from birth. This is rarely the case.<br />steve

Stinky,<br /><br />Maybe it's me, but I still don't understand what you are asking(and I'm from Jersey too). If it is you doing the swapping you should know the years you are getting parts from. I am finding that just because parts don't have the same part number doesn't mean they are not interchangeable.<br /><br />By the way I work right near you...Lakehurst. How is the crabbing?

Re: Ok Whats the big deal on what year a motor is read on....

while yes thats just it I too have found that the same part with different numbers are just that the same the only differance in one case was the lenght of the wires! My point being was it seems really inportant to smoe to get the year of these motors. I think its more inportent to ask if the motor is original first.. I reall need to find a better site to look up part numbers. I have taken so many motors apart in thelast 2 years I can't remember where they go anymore.<br /> Crabbing has been the best in years There a lots and there are giants don't even have to measure them. Some giants aswell like 8 inches!<br />steve

Re: Ok Whats the big deal on what year a motor is read on....

Usually someone like you who has torn numerous motors apart and swaps parts from different years has year-specific questions anyway, like: "what model year 18-20-25 shortshaft driveshafts will fit a 1961 FD15?".<br />Other folks post questions like "my motor won't go in reverse what should I do?" They must list the year and HP and whether it's a manual or electric shift or no one will be able to help them.<br />I like the year and HP in the subject line. I focus on 18-20-25's and Big Twins. They're what I know best and what I'm most interested in learning more about.

Well I just read Yamaha is dropping years starting in 2006. 2005 is the last year they will use years to ID motors. Is Johnson Evinrude next? I hope not. Dealers have complained that the are stuck with Old New Stock motors they didn't sell the year before only to have the new ones no different then last years. Yamaha agrees! They will only used model numbers and change them when they change somthing on the motor. Not good when buying used motors!

Stinky,<br /><br />You're adding to the confusion by double posting.<br /><br />Many powerheads directly fit many years, particularly OMC's.<br /><br />However, electronics packages typically did not. Swapping out electronics packages, or parts of them, is highly unlikely.<br /><br /><br />If the electronics look like an '81', it's an '81' electronic package. Unless you're going into the powerhead, it doesn't matter.

Mercury has went by serial numbers rather than model years for forever. OMC never used model years with any motor under the "Drive Systems" banner. <br /><br />But, to answer what I think is your question about the cross reference guide -- there isnt one. Experience is about the only thing that works.<br /><br />Youre right about the smallest changes dictate a number change. The difference between a 1985 V4 looper stator and a 1986 V4 looper stator is the position of the wires in the connector plug. <br /><br />We've interchanged lots of things that even the OMC factory said wouldn't interchange. Sometimes you just have to tinker with things to make it work. Thats why when folks ask if something will interchange we answer yes if its a direct swap. If modifications are involved it may not be wise to say it will work without explaining the modifications. Some folks just dont have the equipment and / or tools to do the job.<br /><br />On a lot of John/Evin race motors we use Yamaha ignition and Merc lower units. Talk about an interchange!

Re: Ok Whats the big deal on what year a motor is read on....

Dhadley <br />I have found this to be true also. Many parts fit with minor changes. My point being most of the motors I see to be worked on have a hodge podge of parts form every which year. Point beeing is we ask what year and are exspecting to have the correct answer and the parts just aren't there they have been replaced with ????

Re: Ok Whats the big deal on what year a motor is read on....

For the most part we can figure it out as we go along. Like powerheads for instance. Sometimes when we start talking about this or that we ask very specific questions about seemingly obscure things. Its not to dodge the question but to "see" what we're dealing with. Once we establish what we have we can proceed.<br /><br />Many other times it doesnt matter. Like the reg/rec on your crossflow V4. The only stator for a V4 cf is a 10 amp. There are two reg/rec for a crossflow. Either the 10 amp or a 35 amp reg/rec from a V6 crossflow will fit, bolt up and work perfectly.<br /><br />If you had a V6 and were having reg/rec trouble we would start refering to the size of the red wire. That will tell us what reg/rec you have.

Stinky2: Most of the time, we can understand what is written quite well. With out experience, and the proper tool's, you may have, as Dhadly pointed out, a little difficulty understanding us. Throw some common sense in with the tool's, and experience.

Re: Ok Whats the big deal on what year a motor is read on....

Dhadley <br />I do have a V6 Its a 150 I am talking about in my post about voltage problems.

Re: Ok Whats the big deal on what year a motor is read on....

Stinky2,<br /><br />Its getting late so I did not read your post in detail. The Bombarier/OMC web site (BRP) will list all the motors that a particular part was used on.<br /><br /> http://www.johnson.com/docs/100000/0_US.htm <br /><br />Go into US/parts/diagrams then do the advance search. Hope that helps.

Re: Ok Whats the big deal on what year a motor is read on....

Generally,when I come across a 'mis-matched' engineI do 3 or 4 things.Thankfully these are VERY rare where I work.Identify each system.<br />The engine may be an '81,and look up engine parts as that year.<br />The ignition maybe an '87,and look up parts for that year.<br />If the gearcase is different,it's a challenge.I've seen some mechanics cut and weld a shift shaft to make a different year 'work'.<br />If the carbs are different you are on your own,because you deal with carb bodies that may have a different bore size,and someone has swapped jets trying to make it right.<br />OMC years ago DID have a Parts Reference Guide<br />.Newest one I have is probably 1982.But it listed a part number,and told you what models used it.<br /><br />DHP

Re: Ok Whats the big deal on what year a motor is read on....

OK, its a V6 150. Dont know why I assumed it was a V4. Anyway if you have a 35 amp stator you need the 35 amp reg/rec for a crossflow. The ones from a looper have a different shape and are easy to spot. If you have the 10 amp system you can use either a 10 amp reg/rec or the 35. <br /><br />The 35 amp system uses a vented flywheel. The 10 amp system uses a solid flywheel, no holes. The reg/rec's look the same except the ones for the size of the red wire. The reg/rec for a 35 amp system is much larger gauge wire.
