1990 6 hp evinrude questions

[flaxterra]

First off, a friend gave me this 1990 6 hp evinrude motor. The motor is in great shape other than it was locked up from sitting. i decieded to pull it apart and see if anything could be done. to my surprise, it wasnt that bad, just a little rust from sitting, i did a search on here and found some useful hints on soaking it. luckly it came lose without much force. well the other catch was that it was missing the carb. i figured that i could find one on ebay so i didnt think twice about messing with this thing. well now i am have trouble finding a carb for it. the model number is E6RESR. It looks like 6, 9.9 and 15 hp all shared this same carb from the 90's. My question is, the only ones i have found for it are pretty pricey and i dont want to dive to deep in this thing as far as price, so does anyone know of a cross year or hp size that would fit this thing? i just dont know a lot about these small motors, so any info on it would be great. also any places to try online might help. thanks.

Re: 1990 6 hp evinrude questions

Actually, the carbs are quite different from the 9.9 and 15 hp. You need the 6hp carb. Yes, they're a little spendy, but that's what you need. Keep watching ebay for one. It's your best hope. A new one from BRP is going to cost more than you're going to want to pay, I'm afraid.

Those are very reliable outboards, so it's unlikely that you'll find a used carb at an outboard junkyard, but you can try places like tcoutboard.com, or keep an eye on local internet ads for a broken one from the same year. Carbs from other years may fit, but it's hard to say, really. Lots of times, things like linkages change from year to year, and there was a major design change right around your year.

You could also drop in on some local marine stores that service Johnsons and Evinrudes and ask whether they might have a carb off a busted 90 6hp. You just never know, and if you catch them in a good mood, you might find a deal.

Good luck!

Might work, small design differences from the pics of the 2

Re: 1990 6 hp evinrude questions

OK, I did some searching, and the carb for the 90 uses a choke linkage, etc. that's different from the earlier models and much different from the 91 and later models.

That's going to complicate things. While you could probably bolt up the carb from several years of 6hps, it's the throttle and choke setups that get to be different between the models.

For example, they completely changed the way the throttle works in 1991, moving to a new tiller handle and cable operated throttle. So, that's going to leave your 1990 out of using a later carb.

The choke is likely to be the bugaboo on using earlier carbs. There was a change in 1988, from early to late production in the design of the carburetor. The 1989 model actually didn't even have a choke, but used a primer pump instead, as did the 1988. Your 1990 carb is sort of unique from the other models, and appears to be a transition, and was the last to use the old tiller handle design. But, it did use a throttle cable, but not the same one as in 1991. What a mess! You're caught in the middle of a redesign. No more primer, and back to a choke, but the next year they redesigned the carb once more, and changed the choke linkage and air box.

I think you're stuck with the 1990 version.

Those are the issues. The carbs will bolt up to the manifold from earlier models, and probably later models, but the controls are differently-placed.

Complicated issues. I think you need a 1990 carb, along with the air box, and all the external bits.

You say this engine was given to you? Then, I'd go ahead and spend a few bucks getting it going and making it right. Maybe.

Re: 1990 6 hp evinrude questions

well I'm wondering if bolting up a older carb would at least get it to run, and just have to make the choke work by hand. assuming the linkage would hook up. it does have a cable on the tiller but it still has the timing plate that turns the butterfly on the carb...i think. see the funny thing is the hood says its a 7.5 johnson but the numbers says its a 6 horse evinrude. it seems hard to think this thing was someones parts motor cause its in such good shape. thanks for the great info!!!! im going to keep digging to try to figure something out, if i have to buy a carb off ebay, i will. keep up with ideas though, it helped so far.

Re: 1990 6 hp evinrude questions

Hi.
I had 2 johnson's 4hp, one from 85, the second 89 and evinrude 4hp from 91 and johnson 6hpof 73 and evinrude6 hp from 78 and my conclusion is that all this engines have the same carb(i didnt measure venturi outlet but i think it's the same size). different beetwen carb of 4hp and 5hp is pull chocke, but i think it's easy to reinstal one part.i looked at carn of 6hp from 1990 and mine and i think always you can atache AIR SILENCER to the alder type of this carb , in worst solusion your engine will run without this AIR SILENCER, becouse mine didnt have one and runs

Re: 1990 6 hp evinrude questions

The problem is that the earlier carbs, within a few years of yours, don't actually have a choke. Instead, there's a separate primer pump that is used to provide a rich mixture for cold starts.

That's where you'll get in trouble. There's always a way to compensate, of course, but it will require some messing around to make it work. The other problem is that all the carbs for 6hp models are going to be relatively expensive. I think you'll be better off looking for the right carb for your year, and pay what it costs to get the right unit.

Start calling the outboard junkyards, like www.tcoutboard.com. One of them will have the right carb for your model and you'll be in business without messing around with adding a primer pump or fiddling with linkages. If you have to pay an extra $20 or even $50, you'll still be miles ahead, since you got the rest of the outboard for nothing.

BUT -- before you drop $150 on a carb, make very certain that you have good compression and spark on both cylinders. Your outboard was taken out of service for some reason, and the carb has disappeared, having been sold or whatever. So, you need to make sure that your investment will be rewarded by making sure that you have the other elements required for your engine to run. It'd be a shame to buy a carb, only to find out that something else is expensively wrong with your free outboard. I just sayin...

Re: 1990 6 hp evinrude questions

this is really great info, thank you again. I guess if i had easy access to a differant carb, and could make it work, i would try it. but, i dont, and as mentioned the price probaly will be the same for either. I havent check compression or spart so i will probay do that first then begin the search for the correct carb. i will try to keep you posted on the progress. thanks again
