Re: evinrude fastwin 18

jaspurr, your 18hp fastwin is a 1969. 18902 and 18903 are both products of 1969. my personal advice is to stay away from the 18's. i've not heard anything good about them although someone else may have a different perspective on this. if i were you, i'd get a 15hp fastwin, which is what i'm getting on thanksgiving for $400. mine i think is a 1974-78 looper. very reliable! :D <br />also, i'm only pushing a 12ft aluminum starcraft, so it should pop out of the water pretty easy. what are you putting the engine on.<br />i also always say that the first tank of the year should be 32:1 mix, then 50:1 for the rest of the year. anyone one have something that worked better for them? i know altitude and humidity play a role in your choice.

Re: evinrude fastwin 18

I personally just bought an 18 hp fastwin of the same year and model. It had been sitting for about a year, and all I had to do was a little carb cleaning to get it going. I paid $160 for it. I am pretty happy with it so far, but it is a little hard to start sometimes. It pushes my 14' jon nicely. I don't know why you should "Stay away from the 18's" but I am pretty happy with mine. I would definately do it again if the price was right. Oh, I use 50:1, and water should spray out of a round hole in the rear of the motor along with exhaust.<br /><br />Just my opinion<br />-Jacob

Re: evinrude fastwin 18

I'm not sure where Alumistar is getting his info that you ought to 'stay away from the 18s', but it's dead wrong. (And there was never a 15hp Fastwin 'Looper' of any sort. The only 15hp Fastwins came out from 1953 to 1956.)<br /><br />The 18s and the entire 22-cubic inch family of motors were fantastic engines. Great power in a lightweight package. Very reliable and "consumable" parts are readily available. The 18hp models are easily in the top 10 motor designs of all time. If you have a chance to get one, then go for it.<br /><br />As with any engine of questionable service history, one should consider replacing the waterpump impeller, checking all hoses, give the ignition some attention and probably rebuild the carburetor. A compression check can also tell you a lot about how much life is left in the old girl...<br /><br />- Scott

Re: evinrude fastwin 18

I agree with Chinewalker here! Those 22" engines were a very basic design. Parts are readily available, and they are very easy to work on. My son, and I have a 57 & 58 18 HP, they get used all summer long. You just give them a pull on the rope, and go fishing. The 57 look's like the day it was made.

Re: evinrude fastwin 18

hey,hey now....don't start picking! like i said, and i qoute,"stay away from the 18's, i've not heard anything good about them ALTHOUGH SOMEONE ELSE MAY HAVE A DIFFERENT PERSPECTIVE ON THIS." the whole point is that i was going off of my own experience in speaking with other people i've known that have owned them. i'm not getting into some stupid debate about what is and what isn't good. JUST posting what i have heard over the years, that's it! beside the fact that 90 percent of what is posted in forums is EXACTLY that, "hear-say." all information is given on a basis of experience and it is the choice of the reader/postee to do what he/she wishes to do with the information given. now, about the evin15 i'm getting, chine, i appologize for not being "EXACT" on what it is. it's kind of hard to know EXACTLY when you haven't seen the engine, or been told much at all about it except that it's in the 1974-1978ish era of build. that of which ABSOLUTELY makes it a "looper". it's all in the ignition design. as for it being or not being a fastwin, i don't know! i haven't seen it, i just know it's coming from north dakota to colorado on thanksgiving. 400 dollars, delivered. :D now that that's done, why was it i wasn't to upset over not getting into the forums? oh yes, now i remember, because some people just can't give out what they know without trying to belittle and badger a "fellow" iboater. too bad.

Re: evinrude fastwin 18

Umm, Alumistar, I guess my issue is with the mis-information. presented The basic design of the 18hp Evinrude is solid. You may have gotten or "heard" of one that had been abused, misused or otherwise wasn't properly maintained, etc. ANY engine treated poorly will respond in kind. Jaspurr wanted information on whether the 18hp is a good motor. In general, it is. <br /><br />And your 15hp Fastwin, they DID NOT build a loop charged 15hp. Period. Loop charging is NOT the ignition system, its the way fuel is fed into the combustion chamber. Also, if your motor is a "Fastwin" model AND it's a 15hp, then it must be from the 1950s. They "Fastwin" model name was used on the 1950-1952 14hp, 1953 to 1956 15hp, and the 1957 on up 18hp. If someone is trying to sell it to you as a 1974-1978 Fastwin 15, I'd consider getting your money back, as they are misrepresenting it. If you can post the model number of the motor you are buying, we can look it up for you to determine what exactly you're getting.<br /><br />Not trying to belittle you - just trying to state some facts - not opinions. You "heard" that the 18s weren't good motors. That's not "experience". I "know" they ARE good motors. I've owned quite a few over the years. Worked on dozens more. That is experience.<br /><br />Good luck with your new motor...<br />- Scott

Re: evinrude fastwin 18

alright chine, point taken. as i said i didn't want to get into a debate, and we aren't. but, i did say i didn't know much about the motor, just that it's my godfather's old motor. my dad thinks it's about a 1974-78. when i refer to looper, i'm refering to flywheel, coil, condenser, points "loop" ignition. if that is an incorrect verbalization of the ignition system, then, sorry. it is what i grew up around. just like how the english call a hood a "bonnet", and a trunk a "boot". the "loop" is the flywheel creating power in the coil, like a generator, then sending that power to the condeser, which condenses the power, obviously of course, then sending the uprated power to the points, which then intermittently completes the circuit to the plugs, then combustion takes place causing the flywheel to spin more, thus i get the name "loop". like i said, if the terminology is incorrect, then use whatever term you know, it really doesn't matter. as far as a "fastwin", i was under the impression that 15hp and up was a fastwin until the early 80's, but that would be my fault for having been on the other team at that point(mercury), so ya know, hey what do i know? the fact that this is an open mouth forum, all walks of people will hear many different things in here, true? as you said, you've owned the 18's before. cool. i haven't. it doesn't mean that i don't know what i'm talking about. i know that i have been in many discussions with people who have owned them and decided to go with a 15hp, or a 20hp because they said that they hadn't had good luck with 18's. i'm just redirecting what some other people told me. that doesn't make it "dead wrong" or not "experience". it indeed fact IS experience. it is the experience of conversation with "18" owners and their views and opinions. i suppose just like other things, take cars for example, some people swear by dodge, i have never owned a dodge that was even half-decent, therefore, in my mind, they suck! not to offend anyone, of course. may just be the same with the 18 owners, they may have had bad luck, who knows. if you say they ARE good, then you've had a good experience. everyone has the right to produce a few lemons, manufacturers can't be perfect all the time even though we want them to be. just a bit weird that across three different states, i've met i think it was 6 or 7 18 owners and only one of the said he loved his 18, the others were not so thrilled with being "swamped" out on their perspective lakes. and if it's the case that i hear only 1 out of 6 or 7 people actually "like" their motor, then i would be inclined to believe that they're not the best motor out there. in my personal experience, i would say go with a 15 instead of an 18. nothing more, except the parts for a 15 are a bit easier to find, out here anyway. oh yeah, one more thing. i haven't put out the $400 for my 15 yet, but i am going to simpl because i have a '65 9.5 sportwin that just won't quite pull my 12ft starcraft out of the hole at this altitude. personally, it could be a briggs&stratton and i'd still get it on the basis that: 1)it's 15hp 2)we're UP here and 9.5's seem to only have the power of like a 5.5 or 6hp motor, so i figure a 15 will be like having a TRUE 9.5 or, beset with happiness, a "10hp"!! :D as far as all the above "information", if needed, i concede that i don't have all the knowledge, or the time to gain all the knowledge, however, if someone asks i am always ready to give a very in depth, thoughtful opinion of my own. unfortunately that is the case even when some information may not be exactly correct. that, however, doesn't matter because it is what it is, an opinion. ;)

Re: evinrude fastwin 18

either way, as long as the motor is taken care of, regaurdless of what it's size, make or model is, it will last a long, long time. just remember to give it a kiss once in a while or you could be hating life at dusk, a mile out in the water, with only the sound of the wind to soothe me. you, i mean you. not that that's ever happened to me.....................o.k., it has once, or twice.......or more........ :)

Re: evinrude fastwin 18

You are saying that out of 6, or 7 owners you knew, only one liked his 18. I have been working on OMC engines since 1962, and owned one since the early 50's. I could'nt even begin to guess at how many 18's I have worked on over the years. I can say for certain that I have never run across 6, or 7 dissatified owners. When you come on here, and say you have a 15 HP Fastwin looper, somebody is going to set you straight. That's what people come here for, straight answers.

Re: evinrude fastwin 18

I have an 18hp Fastwin.I dont know what year.It has never gave a dimes worth of trouble.It is hard telling how many hours it has on it.It can set for a year and will start within three pulls.I can promise you there has never been a better motor made.I had(first motor)a 1947 Mercury 10hp(or close)that was a really good motor.I should have kept that one.

Re: evinrude fastwin 18

Hello gentlemen,<br />Thank you all for your replies, I cleaned the carb and plugs and it started and run and ticked over fine, it it a bit smokey mind you, but it's never been run for a long time I don't think.I didn't put the right mix in so I don't suppose that would help, I will fix that right away, "50/1".<br />there is no water coming out the engine, so I will have to look at that, is it an easy enough job to do the impellar? can anyone help me with that? could it be just a blockage?.<br />thanks again for your help,<br />cheers,<br />Jaspurr

Re: evinrude fastwin 18

Hi Jaspurr,<br /> The impeller is fairly straight-forward. I highly recommend getting a manual before tackling it, though. A search of these boards will likely turn up a step-by-step approach somewhere, too. The impeller is cheap insurance - generally between $10 and $15, depending on where you get it. OEM part # is 0375638, and NAPA/Sierra number is 18-3002. <br />- Scott

Re: evinrude fastwin 18

Well, I recently replaced the gear case on my 18, and it is about a 30 minute job from start to finish, for someone who doesn’t know a lot about outboards, yet mechanically minded. Here is what I did (as far as I can remember):<br /><br />1) Disconnect Shift linkage<br />Remove the cover on the leg that has the 2 straight screws holding it on. Inside, you will want to loosen the lower of the two bolts. (This will disconnect the linkage)<br /><br />2) Remove Bolts<br />I believe there are 4 or 5 bolts that hold the gear case in place. I think there are 4 that bolt upward, into the lower unit and one in the rear that bolts down, into the gear case.<br /><br />3) Pull<br />The gear case should now kind of slide down. Keep in mind that the shift linkage, drive shaft, and water tube all have special places to go, and may take some wiggling to get loose. <br /><br />4) Disassemble the water pump<br />The water pump is located on the drive shaft. To remove the top cover, remove the three straight screws. Now, the water pump will come apart, and slide up the drive shaft. Be sure to keep up with the pin that drives the impeller on the shaft. <br /><br />5) Reassembly<br />Just do it backwards. Remember to get the water tube back into the correct position. When I did mine, I think one of the rubber boots that sealed it broke, and I am not getting a good seal, but it worked long enough to test and get a new one. <br /><br />Please keep in mind that this is a semi hurried version way that I did it the other day. I probably did something wrong, and the mechanics that have been working on these motors their entire lives will probably pick it apart, but it is a little guidance that would have made me feel more comfortable while fixing my own. Your water pump impeller will probably come out in several pieces, as it will have dried up over years of sitting.<br /><br />Good Luck!<br />-Jacob

Re: evinrude fastwin 18

One thing not to be overlooked is the small o-ring at the top of the driveshaft. It must be in place and there must be a good dab of waterproof grease in those splines prior to reassembly to the powerhead. The crankshaft on these motors is steel and it will rust if driveshaft is not greased. The o-ring helps keep it all up in there when assembled, so it must be present and in good shape, too...<br />- Scott

Re: evinrude fastwin 18

Thanks, Chinewalker, I didn't even know we need to do such a thing. I am pretty sure that when I took mine apart, there was no O-ring. I guess that I will need to stop by the hardware store and get me one and some grease. <br /><br />Thanks!<br />-Jacob

Re: evinrude fastwin 18

Hi Gents<br />I have lower unit off now, and only broke one bolt when removing it, which I manage to get out with grips once the lower unit was out the way, then I manage too shear the three screws holding the Impellar housing in place, I then had to batter the housing back and forth for twenty minutes until it gave in and let go, the good thing is I have some sharp drill bits and a brand new Tap and Dye set, <br />the Impellar itself is almost worn right through on one side and is a bit too flexable, the housing is well corroded and where the drive shaft goes through it it is severely corroded, according to the manual I have just got I think there should be an O ring,<br />I have ordered up an Impellar kit, so hopefully it will go back together without any great hitch and off we go<br />cheers<br />Jaspurr
