Re: 1972 100hp

Sounds real good. I would have guessed that the OEM would have used bronze, but heck if nylon was good enough for them it should be good enough. Is the T&T you are using the one that has the cylinders on the outside of the brackets or the later model that fits in between? I am already starting to look for the swivel bracket to do the mod on my motor and would prefer the later style. Keep us Posted.<br /><br />Russ in Texas

Re: 1972 100hp

Looking forward to see'ing the photo's of your project. You had me lost there on a couple of points, so some pictures should clear things up. You made mention of using a lathe. What make do you have? They can sure bail you out of a lot of problems.

Re: 1972 100hp

I'm using the later model t&t, the one that fits in between the transom mounts. It was off a '76 150hp originally.<br /><br />I don't know what model the lathe is. I'm good friends with the owner of the custom bike shop here in town (actually help him build frames and custom parts and such), so I get to use his lathe whenever the need arises. I actually have to re-teach him out to use it because it's been so long since he's touched it *laugh*<br /><br />I'm still hoping to get to this today, but my car needs to be cleaned out and detailed really good first so I can try and sell it. That's the first priority, then I'll get to the other, daylight permitting (hard having the motor 50 miles away when you're trying to do that mods *laugh*)

Re: 1972 100hp

Man that's exactly what I want to do with mine. I never really cared much for the first generation tilt & trim. I don't like the "batwings". The style you are using is so much cleaner because it fits between the mounts and is practically hidden.<br />Looking forward to the pics. Have a safe and happy holidays.<br /><br />Russ In Texas<br /><br />P.S. My friends in B.C. tell me its getting abit chilly in the Great White North. Not real comfortable for boats or bikes. At least maybe you will have a white Christmas.

Re: 1972 100hp

Yeah I never got to the modifications today, the car took WAY longer then I expected. Oh well now it's saleable which is good. Kind of bothers me though because I did hear it was supposed to be bloody cold over the next week. They're calling for above freezing temps on Christmas eve and Christmas day, but I'm not doing ANYTHING those two days I guess all I can hope for is that it's warm afterwards, or else I'll just bundle up and deal with it. Took apart a motor outside on the driveway two years ago when it was -50 celcius so I should be able to manage this. <br /><br />So if you don't hear from me in the next week with pictures, you know why But I will get some taken when it's complete and going together so everyone has a good idea how it goes together. And it HAS to go together, my back didn't like last year at all Anyways, happy holidays and Merry Christmas if I don't get to it before then!

As I stated before though, the cost isn't worth it for me. The time I can manage, not the cost.

Re: 1972 100hp

Just wanted to let anyone know trying to follow my progress, I am now kicking myself for not getting this done last Sunday. It's been bloody cold out and I've been enjoying the warm indoors and the time I've had off from work relaxing. But because I want this done ASAP and want to be able to get pictures to everyone so anyone that is going to attempt this has something to go by, I think I'm going to put on my ski-doo suit and bear the frigid temps to get it done.<br /><br />I hope everyone had a very Merry Christmas and that Santa was good to everyone

Re: 1972 100hp

Hi you mention the tilt tube steering I have a 73 135 the steering arm goes in the motor right above the transom. Is that what you are referring to.. Thx<br /><br /><br />

Originally posted by R.Johnson:<br /> If you get hung up on anything making this switch, let me know. As I pointed out, gaining that tilt tube steering is another plus. It makes rigging much easier.

Re: 1972 100hp

The stearing arm bolts to the motor right below the cowling, then the stearing stem itself goes through the swivel bracket, and in the case of yours (maybe) and for sure the '76, the stem is a tube as compared to a piece of solid round stock. I personally don't see the benefit of this, but I don't know that much about boats I could be WAY off on this.

Re: 1972 100hp

you said you were converting a 76 140 hp <br />are you sure its a 140 they were made in 77,78,79?<br />How's it going btw

Re: 1972 100hp

Sorry my mistake. It's a 77, but I believe 76 motors had the same style tilt and trim (single large ram in the middle with the two smaller trim rams that mounted between the transom brackets). <br /><br />That's what the tilt and trim is off of, same with the transom brackets and swivel bracket. Trying to make it work with my '72. Only problem I'm having now is the swivel bracket at the bottom end doesn't accept the '72 lower mount properly. I started grinding away at it for the clearance I need but it's been bloody cold out lately and hard to bear (I've lost alot of weight last year and not having the extra padding makes it tough ). We're also in for a big snow storm tonight so even if I do get this part done, I don't think I'll be able to try it out for a while because the farm where it's stored has a tendancy to build up a nice snow drift across the entrace to the storage area. I will definately try to get there though, I'm anxious to see this work!!

Re: 1972 100hp

Well not good news today. That blizzard hit and it hit HARD! The cities been out three times plowing the streets and as of 12 hours after it starting, it's still snowing. I think we got a good 2 or 3 feet of snow today. This means I cannot get to my boat to finish the power tilt and trim installation until some of this melts which might not be for a while <br /><br />I'm going to keep working on the swivel bracket but because I don't have my motor at the house, I really won't know what I have to do to the swivel bracket until that time. I'll be taking pictures of it so far so you all can see the progress I've made up until this point, but the money shots won't be happening until everything is all bolted together.

Re: 1972 100hp

Hey SC I brought my T&T home today. Came off of an 83 model V4. Lucky for me it had never been in saltwater. Already have it taken apart and ready to get stripped and repainted. I think I see what you mean about having to remove a little from the bottom of the swivel bracket.I'll let you know how it goes.<br /><br />Regards<br /><br />Russ In Texas

Re: 1972 100hp

Sounds great. Let me know if you get the lower mount to fit properly. I'd like to get mine done soon, but because of that stupid blizzard I can't get to my boat to even work on it. I can start cutting the lower section of the swivel bracket, but I don't want to take too much off, will cause the motor to move up and down. Guess I'll have to wait now, good luck to you and keep us posted!!

 

[skyguy59]

Re: 1972 100hp

Good news and bad news. The good news is that I got the lower mount to fit correctly. The bad news is that I didn't use the stem and lower mount off of the 72. I found a stem and mount off of a 73 or 74 that had T&T. The lower "horseshoe" is scalloped on top to allow for extra clearance. It fits perfectly without grinding anything. Unfortunately the stem and splines are larger in diameter than the 72 and smaller than the 78 and later so you have to have both the stem and lower mount. All that is left now is cleaning and painting followed by reassembly. I'll let you know how it goes.<br /><br />Russ In Texas

Re: 1972 100hp

Where did you get the stearing stem and lower mount from? Did the stem fit into the swivel bracket correctly or did you have to make bushings for it like I did for the original '72 stearing stem? Let me know, if you found the stem and lower mount locally if you could pick up another that would be a huge help to me. If you've got pictures I'd like to see it all put together, want to take em to the Johnson dealer Otherwise I'll just wait until mine is together. Thanks for the update!

Re: 1972 100hp

Actually I went looking for another 72 stem so I could build my unit up and do a direct swap instead of taking my motor apart ahead of time. Thats when I found this one. I had to make bushings for it the same way you did for the 72 stem. It is larger in diameter than the 72 but smaller than the later stem. It measures 1.365" in diameter. The bottom bushing will only have about .030 wall thickness. I was lucky to find one in good shape. You don't find much down here that age that is not corroded all to heck. I'll keep a look out for another one.<br /><br />Russ In Texas

Re: 1972 100hp

I'm going to keep my eyes open as well, thanks for that little tid bit of advice though. We don't have any wrecking yards here for boats, no used parts at all. I may just keep going down the path I'm going and see where I end up Just need my motor so I know how much to take off.
