Mid shaft alignment tool issue

[451sdad]

I ordered a cold fusion tool to align my new solas mag pump in my 1993 SN. Pretty disappointed the tool doesn't fit a SN. Nothing on the CF website says RN, just Yamaha style midshaft. Looks to be easily adaptable for both with different holes. What are you guys using for the squares?

90-93 has a smaller midshaft housing

Just my luck.

Just do it visually, driveshaft exits the fire wall tube (centered) and in the same plane. Mid shaft mounting holes align with firewall mounting holes, without prying, lifting or pushing on mid shaft. Here's a link to build a bob, I'd imagin it's the same on a squar nose

You're not alone - sellers don't even ask what Yam you have.
Sympathies mutual!

I just use a socket, a drill bit or rod that fits comfortably between shaft and the opening. You can easily tell when the shaft is centered.

You can use the larger midshaft in your square.

The bottom 2 bolts will line up with the larger midshaft housing. Drill and tap the bulkhead for the third (in the fiberglass). I wasn't sure how long it would last but I've had an 8mil able/hpe in a square like this for almost a year. The smc (fiberglass) holds threads pretty well.

Once you do this you can use the cold fusion tool also.

Sounds sketchy! Lucky it works I guess.

Eh, I was unsure also but it's a ratski so I rolled the dice. The bulk head is pretty thick in that area as well. I've had the midshaft out several times since and it's still holding fine. If everything is aligned properly, the bolts are not really taking much load.
