Calling OMC Guru's!!!!

[SeaMasterZ@aol.com]

Couple of questions ... <br /><br />Would the lower unit from a 60 40 horse Johnson work on a 64 40 horse Johnson?<br /><br />also ...<br /><br />as a measure of last resort, I hate the idea of scavenging my 35 horse 59 Johnson, would its lower unit fit the 64? I may need to use the long shaft extender from the 35, as big as that danged 40 is, I think its a short shaft - barely fit in the cavern I have that passes for a trunk in the Impala, but I dont see the extention on it (never doing a 4 am purchase again, im STILL tired from trying to undersleep myself enough so I can NOT fall asleep early, lol)<br /><br />There is yet another clunker up for sale, has a decent lower unit, so the man sez, and its close enough for me to take the old girl out for another drag home ... I dont know what it is about the old RD series, they just look so modern for such an old motor, without that hokey "space ship" look of the old evinrudes ... and way better than those Fon du Lac clunkers (they run lac fon due, cheezy! LOL)<br /><br />So, there it is ... I apparently need a lower unit, I really cant see an adjustment making a difference in this "cant feel any detents in the shift linkage" situation ... and dialysis was not kind to my baby, so I stayed home to comfort her (but if shes ok tomorrow, HELLO DELAWARE, lol<br /><br />I cant seem to get an answer on the how far are twin engines supposed to be placed, but apparently there is thoughts afoot that neither engine will be running soon, let alone both of them!<br /><br />When something is bubbling away in the tank, Ill be back about the twin motors thing tho,

Re: Calling OMC Guru's!!!!

Ray.... The lower units will interchange as long as the water pump setup is the same (two tube), but pay special attention to the driveshaft lengths. Some of those shafts will differ by only 1/8" or so. If you attempt to use the longer length shaft in a engine that normally uses the 1/8" shorter shaft, that will exert excessive pressure between the powerhead and the lower unit, resulting in a binding action.<br /><br />The eariler models did not incorporate the propshaft and clutch dog spring loaded detent setup, however they may be interchanged from one unit to the other also. Note that the clutch dog must be set up for the detent.... the eariler dogs will not work!<br /><br />Now, notice in the above that my reply pertained to your problem and you did not need to read through any other distracting info that had nothing to do with the problem.<br /><br />No offense or adverse reflections intended, but your posts include so much unrelated info that I have avoided getting involved prior to this as I did not desire to read through a lengthly post that included unrelated type, including that long drawn out signature.<br /><br />Best to use the K.I.S.S. method (Keep It Simple Stupid).... again no offense intended (that's simply what it's called) and I hope sincerely that you are not offended.<br /><br />Formerly from Millville, NJ.

Re: Calling OMC Guru's!!!!

Thanks Joe ... I know I tend to get verbose, but thats just my way<br /><br />Ill attempt to be concise - there is a 1960 Sea Horse 40 I can get as a parts motor, its a short shaft ... I dont know if its a detent type or not, my 66 feels like there is nothing connected, so I dont know ,,, <br /><br />if the shaft in the 66 is too long for the 60 lower unit, would a machine shop be able to take 1/16 off of each end without affecting the performance/longevity of the unit? also, will the 1/8" extra be apparent when I put it together, or only after I start it up and it starts squalling?<br /><br />Millville is beautiful, they are cleaning up the Maurice River, and they are converting the downtown area into a sort of renissance center, art galleries, sculptures, etc<br /><br />(I like to think the signature is funny, lol, even if it is a bit long)<br /><br />but there I go getting wordy again!<br /><br />Again, thanks Joe, damn shame you moved, I could be bugging you constantly in person<br /><br />then again, saved you from that restraining order ... LOL

Ray.... You asked "if the shaft in the 66 is too long for the 60 lower unit, would a machine shop be able to take 1/16 off of each end without affecting the performance/longevity of the unit?"<br /><br />I have never run across a shaft that was different in length when the lower units were identical in size, shape, etc, regardless of whether the shaft was a detent type or not. However, if it was longer/shorter, having it machined would be a judgement call you'll need to make.

Re: Calling OMC Guru's!!!!

ah, ok ... how do I know if its a detent type?<br /><br />(jeeze - hes gonna hate getting involved with this one!)<br /><br />Signature better?<br /><br />Thanks for the help, I sure need it!<br /><br />

Re: Calling OMC Guru's!!!!

will the manual tell me if I have a detent type?<br />I have a deal together to get a parts motor, a 1960 model, sometime tomorrow, and I should be able to get the wasps killed and the manual out of the truck before going to get the motor, Im sure the guy wouldnt be too pisssed over me not gettng the motor, its only 50 bucks ... <br /><br />jeeze, ten lines for a one line question, no wonder I get in trouble! (spaces count apparently!)

Re: Calling OMC Guru's!!!!

well the local marinas are no help, does anyone know if that 1960 40 horse johnson is a two tube water pump or a one tube? <br />I have a parts motor on standby thats only a 2 hour ride away, and I would happily make the ride ...<br /><br />IF I KNEW THAT THE MOTOR WAS A TWO TUBE!!!!<br /><br />I really dont want the guy tearing it apart to find out, I like doing that part!!<br /><br />thanks whoever can come up with the 50 dollar question!

Re: Calling OMC Guru's!!!!

It's a two (2) tube water pump setup.

Re: Calling OMC Guru's!!!!

thanks Joe, Ill go get that motor tomorrow, thank you thank you thank you, lol, how do you like the shortened signature? I kept advice and humor and still kept it me without it being nine miles long, lol<br /><br />I really do try to keep it simple ...<br /><br />Its just that the concept escapes me!<br /><br /><G>

 

[SeaMasterZ@aol.com]

Re: Calling OMC Guru's!!!!

i kept it simple for nearly a minute, should that detent situation be different from one to the other, does the shift rod go in differently? or is it all contained in the lower unit, just swap shifters and rods?<br /><br />I can take a car down to a pile of parts and reassemble them, I really do know how to turn a wrench, just not on salt water crusted beasts, lol<br /><br />well ... not yet, anyway<br /><br />thanks for the patience!<br /><br />

Re: Calling OMC Guru's!!!!

The detent on one 40hp would be the same as a detent setup on another 40hp (years interchange) if that's what you're asking.<br /><br />The shifter dog must be facing in one particular direction and aligned so that the detent balls align perfectly with the groove machined within the ID of the dog. If the dog is turned 180°, the alignment is off and will cause problems.<br /><br />If memory serves me right, I believe that there were grooves on the face of the dog that had to face forward gear. Check the manual.<br /><br />Note.... Look at the top of any post. There is a "edit" box there whereas you can add to your post rather than insert another one when you find you've made an error, or suddenly (just after entering one) remember that you intended to enter something.

Re: Calling OMC Guru's!!!!

Thanks again Joe, I do listen and occasionally learn - since I cant find my old Clymer and Seloc manuals Ive reordered them, but my curiosity and lack of patience drive me to asking questions that I otherwise cant answer yet ... and the people on here (you in particular) could write volumes on the inside information that the manuals DONT cover, like when you told tinkerer that he could bleed down his tilt n trim by careful application of low pressure air ... stuff like that, wisdom accumulated over years of experience<br /><br />a long time ago, I was told that a fool learns by his own mistakes, a wise man by the mistakes of others ... ive tried to live that way as often as possible<br /><br />thank you for sharing the knowledge you have accumulated over the years, I for one greatly appreciate it.
