What screws?

Use the 847 on the skeg screw threads.

Oh alright, so the 3m 847 is a substitute for both Sealer 1000 and perfect seal #4 thread lubricant?

Re: New to me 28hp evinrude speeditwin not spitting water

Well it is a substitute for the 1000. If I remember correctly, the perfect seal #4 is just gasket sealing compound. The 847 will work perfect for the skeg screws, underneath the impeller plate, all seals, etc...

I do like the OMC Gasket Sealing Compound for the impeller housing bolts, and gaskets. The 847 can also be used for resealing the cranks case halves with a spaghetti seal.

I have the same motor,you get that timing set right between the marks,and she's as smooth as silk@idle and a darn good runner! I mix it@ 50/1 and it never gives me any problems. I have the pdf,but it won't let me fwd it to ya,I tried but it says no go. Maybe by chance it went anyway?

I've got the lower unit all reassembled and everything seems to function great! Thanks alot you guys for helping me with this, especially HighTrim. I find myself learning new stuff here all the time by my fellow Iboaters! Thanks again

Re: New to me 28hp evinrude speeditwin not spitting water

Hey guys, i was wondering if anyone knows the torque specifications to the 7 screws that hold the lower unit to the motor?:
I was just trying to attach the lower unit, i tightened the screws until snug and one of them snapped right off! Luckily there was enough stud to get it out with vice grips:
This is the kind of bolts that are used to hold the lower unit on: Those bolts had no washers or lock washers on them, should i have washers?

Re: New to me 28hp evinrude speeditwin not spitting water

No, you don't use lock washers when you're attaching aluminum parts together as they can cause the bolt to loosen.

Re: New to me 28hp evinrude speeditwin not spitting water

They don't need specific torque. Just tighten them up. Strange. That is 1 bolt I don't think Ive broken before, lol. At least you got it out ok.

Re: New to me 28hp evinrude speeditwin not spitting water

Alright, so i don't need any Locktite on the bolts? Nothing need be added to the threads? Just tighten them down till snug?

Re: New to me 28hp evinrude speeditwin not spitting water

is the bolt shown in the pic ss, or zinc coated????

Re: New to me 28hp evinrude speeditwin not spitting water

I believe it is stainless steel since it is 50 years old and has shown no sign of rust. So do i need to add any locktite, anti-sieze or anything to the threads?

Re: New to me 28hp evinrude speeditwin not spitting water

If you're in a salt water area it may not hurt to put a small amount of marine grease on the threads.

 

[BoatgoatmfgVT]

Re: New to me 28hp evinrude speeditwin not spitting water

Nope, no salt water. So alright, i can just put the bolts on, snug em' down and call it good? It seems for something like this you would at least put some sort of threadlocker, so i dont lose the dang thing into the deep deep lake

lol..sorry....my eyes are of the same vintage, and do show signs of rust!!!

Re: New to me 28hp evinrude speeditwin not spitting water

Nah you will be fine. Tighten them up and you are good to go. Put some grease on the water line and grommet to help guide it up straight without pinching.

Re: New to me 28hp evinrude speeditwin not spitting water

What about the shift rod? Does that have to be connected in a special way?

 

[HighTrim]

Re: New to me 28hp evinrude speeditwin not spitting water

Shift the motor into forward, that will get the coupler up and out of the way while you line up the water line and bolt it up.

Disconnect the plug leads.

Slide the gearcase up, ensuring the water line goes in straight into the grommet. When she bottoms out, slowly turn the prop until the splines align and she slides up smooth the rest of the way. Now install a bolt to hold it put. Now you can install the rest of the bolts.

Now with needle nose hold the lower shift rod and guide it into the hole in the coupler while you shift back down into neutral. Ensure the detent in the rod is perfectly aligned with the hole in the coupler then install the bolt. Just snug, don't twist the stuffing out of it or it may strip.

Now spin the prop by hand, ensuring it turns smooth while in neutral. Shift into forward while still spinning, should stop it. Back to neutral, spin free again. Into reverse, should stop it. If you can test all gears and all is well you are good to go. Reinstall cover plate and test water pump output in the test tank.

Let us know how it goes.

Re: New to me 28hp evinrude speeditwin not spitting water

Hey guys, its been a while since i have done anything with my motor or boat. I got the whole lower unit completely rebuilt and reassemble thanks to you guys. So today a buddy and i went out to go for a nice day of fishing, only to find the propeller would not spin while in gear.... This is what is really odd, is i can put it in gear and then turn the prop by hand and it will spin the flywheel, but once i have it running while in gear the propeller does not spin. Could it possibly be that i do not have the shift linkage properly alligned? The motor is spitting water just fine now, so the down shaft is obviously making contact with the splines. I just dont get it. All i can think of is i did something wrong with the gearcase rebuild, or that the shift rod linkage isnt attached right. Another thing i possibly thought of but doubt is the propeller hub has slipped, although it did spin before i rebuilt it. If anyone could help that would be awesome, thanks
