So we got the l.u. off and suprised to find out it is a short shaft....


Maybe since it is a 94 the weren't putting long ones on toons...


Waiting to hear back from SEI on replacement.

Mabe that means that the short unit will save you a few bucks in relpacement.

Nope all the same 845.00.

I will tell you what that sucker came off in 30 minutes. If any of you are worried about replacing impeller,. It was five nuts and almost didn't catch it when I gave it a smack.

I'm sure that pink tool box helped you gather the strenth to lift it though right?




I will be relpacing my impeller probably at the beginning of next season, and have a saved youtube video for help.

I just knew when I took those freakin pics someone gonna give me shit for my pink tool box....

You set yourself up on that one Curtis.
Hopefully you get that think back to gether soon. With this 90+ degree weather we've been having, that water will warm up quickly, and be ready for some swimming & drinking.

Man it was great down at the lake we got so much done....
LU taken off.
Distribution box put in no more pvc over road with shower power hooked to main box.
Leaves burnt.
All 4 wheelers running great.

and 60 this weekend crap....

Well don't this suck

Based on the serial number you provided, I believe your unit is the 3-jaw reverse clutch style. Ours is the upgraded 6-jaw reverse clutch and the only way you could use our lower is if you replaced the shift shaft which would require you to remove the power head. The 12 is referring to the number of teeth on the pinion gear not the splines on the driveshaft.

Thank you for contacting SEI.

That does suck...

I guess you could B ust O ut A nother T housand and just buy a new to you motor instead... and sell your's for parts. Should be a descent selection dowm by Truman / LOTO.

shit we doing good just to afford the Thousand now....

I am still looking for shift shaft.

They prob fed you that line of crap after seeing the pink toolbox...

so my local mercury service marine ( thats 40 miles from closest lake!) says he will look at the old one for 50 bucks he said it sounded like a pin may have sheared. To install the new 200 dollar shift shaft you have to pull the powerhead. CRAP! So I think I'll take it in to him and see how bad it really is.

What was the original problem? I have spent some time in that type of lower unit. There is really not a lot in there but every part is big buck$.
Pulling the power head is not really that big a deal. I am not sure what the difference is in the shift shaft tho.
Are you converting from "turn" to "up and down" like the guy with the 50 (adjusting nut in the shaft)

I imagine that is more than just a shaft.

I wish I knew more to be able to help you out Curtis. I hope your guy @ the Merc place can get it figured out for you, and get you back down the road .....rrrr wake.

Ok. Forward Reverse and clutch all worn down

The mechanic stopped added up parts at 900. I checked online and found everything to rebuild lower unit. Gears, seals, and water pump for 750, he will put it together for 250.

I have three choices.

1. Rebuild original lower unit = $1000 bolt right up.
2. Order sei and shift shaft = $1000 and maybe 2 days labor. 3 year warranty
3. Ebay L.U. blown power head looks like new = $550 bolt right up.


what would you do? Money is an issue!
