Volvo SX Drive U-Joint
 

My name is peter noordermeer and I designed and build my own 42' powerboat of wood !

This winter I'm changing my old 290 volvo drive's into 2 new volvo SX drive's

What i noticed is that there are several type's of u-joints !, the u-joints that or on my new drive's now are different than on pictures i see on the Internet. Can someone tell me more about it ? My drive gear ratio is 1.79:1 I have got two upgraded 350 vortec engine's.

Is the u-joint on every SX drive the same or do I have a new type ?

I have a SX drive and put U joints on it last year. Can you tell me more about what differences you saw? Just as a heads up the SX drive shaft assembly is balanced and mark the connections and orientation so you can return the shafts to the same location.

I saw in the GLM marine cataloq, that there are 2 different u-joints, one with a grease nipple and one without GLM part number 38020 + 38030. The one with the grease nipple 38030 they say that it is a Heavy Duty.

I had a grease fitting on the factory u joints and replaced them with the fitting version, forgot about that. I figured the ability to grease when I pull the drive off for annual maintenance is a good thing.

See Picture's for the U-joint. They are brand GKN Automotive. I dor not know or they can handle 400 Hp ?. I bought the drive's new so Volvo is using GKN U-joint. My reduction is 1.79:1
