Question for Joe Reeves

Re: Question for Joe Reeves

No apologizes necessary. We gotta get our answers one way or the other, sometimes it aint pretty. Is your motor as bulletproof as mine? I just bought it & it is amazing. I didn't expect to have an RPM read of 6000 but I knew it had good power just by how fast it pulls out of the hole w/ a boatful. $1500 for the boat, motor & trailer.....gotta love it when someone just has to get rid of something.

Re: Question for Joe Reeves

Yes I think the V-4 engines are bulletproof if you maintain them. I only paid $500 my bass boat, but it wasnt running at the time. With a little work, it runs great and is very dependable.<br /><br />Can anybody answer my orginal questions? I am not questioning anybodys integrity, I am just looking for answers. I am interested in how the tach receives the pulse from the stator?<br /><br />Original questions:<br />It has 8 poles but it only emits 6 pulses?<br />Why did OMC tachs have different settings on the back if all of them emitted 6 pulses?<br /><br />Would the following statements be true?<br />"As said before the number from 1-6 represents the number of pulses from the stator. A stator will give out a pulse for each pair of poles so for 6 pulses you would have a 12 pole stator."

Re: Question for Joe Reeves

I found it here. web page <br />I have read it several times in other peoples post on here. It seems to be common knowledge on this board. <br />I also found it here under Paul M. post. web page <br />and here under Dhadley. web page

Re: Question for Joe Reeves

Again, I wasnt questioning your knowledge about the subject, I was just questioning the subject at hand. My OMC manual does not give specifics when it comes to the tach. As a matter of fact it does not talk about it at all, just the charging system.<br />I will continue to search for the answers to my questions, perhaps by talking to the local mechanics.<br />Thanks.

Joe, what happened to your replies????? No fair erasing them before I get a chance to see them.<br /><br />

Re: Question for Joe Reeves

Basscat - after reading the previous thread on tach settings, I set my tach from 6 to 4 on my '76 Johnson V4. Thanks to you and Indymike for setting the record straight regarding the correct setting on older OMC V4s. There seemed to be some misinformation floating around that all OMC V4s needed to be set at 6. Apparently, this is only applicable to somewhat (post '77?) newer motors. I'm now hitting 5600 at WOT and am no longer living in fear that I'm lugging my motor.

Re: Question for Joe Reeves

McGR<br />The discussion you read from me on my tach setting<br />was direction I got from teleflx for their tach and an eight pole stator. In fact the tech from teleflex said" Johnson/Evinrude has NEVER informed us they made engines with 8 pole<br />alternators. If your engine has an 8 pole alternator, set the selector<br />switch to the 4P position".<br />Like I said before it seems right but I have not verified the accuracy of this with a shop instrument. For myself the jury is still out. I'm setting up an appointment to have a tech look at it . Don't take this to the bank. I'd hate to hear you smoked your motor from the results of an inaccurate tach. I'm just another hack here trying to learn a little. I wish some of the real techs here would jump in some more on this. Remember it don't matter what your tach says if it's not accurate.

Re: Question for Joe Reeves

Thats why I bought this subject up. It seems there has been a lot of confusion on this.<br />I too have mine set on 4 now, and I am 99% sure it is reading accurate. Again, I am in search of facts. Surely somebody knows the exact details on how the tach reads the pulse signal from the stator, even though my OMC manual does not discuss this.

Re: Question for Joe Reeves

I like to believe I'm getting more accurate readings now also. My rig is a 17' aluminum V and I'm running a 19" stainless prop. I also installed a CMC power trim, so my trim angle isn't an issue. The motor is set as high as possible and runs like a champ. I found it hard to believe that I was only turning around 4600 previously. Nonetheless, beyond the wishful thinking, it would be good to get this one setteled for once and for all.

I was banking on Joes advice given his years of OMC experience & set my tach to 6 & it seems to be correct. At 6 I get 800-1000 RPM at idle, 675-800 at idle-in-gear, WOT RPM is 6000 running a 13 1/4d x 17p prop with minimal tilt. I also have a 4 blade 13 1/4d x 21p Renegade arriving & will see what that turns as well. Joe seems to have become fed up with this forum as his replies have all been erased, which I find a little disturbing

Re: Question for Joe Reeves

I believe that Joe has had enough of this thread. He tried to explain why he told you what he did. It's easy to get frustrated when people ask for advice and then either don't take it or question it. He has been around these engines since rocks were soft. I'm not starting a troll or anything but when I did read the responses I took them wrong also. Seemed like the young buck challenging the old stag. Just MHO.

Joe's a goodun guys and I have every thing he ever advised any one on printed of on card stock and filed away. When I need assistance on the older ones I look at his replies and find my answer. It hasn.t failed me yet/

Davey just do a search on here for his posts and copy off what you want or need. That is the beauty of this site.

All I did was ask questions, thats what this forum was designed for.<br />I didnt challenge ANYBODY. I even said I respect his 30+ years at OMC. Its not my fault he got mad and deleted his post.<br />The questions still stand for anybody to answer.<br /><br />"It has 8 poles but it only emits 6 pulses?<br />Why did OMC tachs have different settings on the back if all of them emitted 6 pulses?"<br /><br />Would the following statements be true?<br />"As said before the number from 1-6 represents the number of pulses from the stator.

Re: Question for Joe Reeves

Basscat, I'm still perplexed too. I've done some research on-line and according to Teleflex other than motors below 70hp, all OMC motors should be set at 6. See Link Below<br /><br /> http://www.tflx.com/obtachtrad.html <br /><br />Nonetheless, it's hard to argue with the logic of counting the physical number of poles. Hopefully some Guru will chime in and get this thing sorted out...
