It's a 85 J150TX
The last time I had the lower end off, I noticed the splines on the driveshaft going into the powerhead are getting worn.
Am I going to have to replace the crankshaft also, is it a harder metal that fails after the shaft?
Ok, it's not really a test stand. It's sitting with it's mounts on a heavy duty dolly.
I want to start it to test compression and adjust timing and rocker arms.
Question is; how to get water to it?
My idea is to connect a garden hose with a Y to both hoses at the back of the exaust...
I started working on this motor more than a few years ago and am just getting back to it.

Looks a lot like a big Newport. I think the hardtop was someones project. Really cool front nav light !
Just curious,
I recently took apart a high profile 225 - 245 HP drive for parts and found the water pump shaft and the upper shaft stripped.
In a past thread Howard Sterndrive mentioned this as common but didn't explain why.
What causes this ? It looked like a pretty dramatic failure. The...
I'd like to know what the HP rating and gear ratio is for this drive.

I unbolted it from a 72 350 SBC . They were in the bed of a pick up so I have no idea about it's history. Didn't see any...
I'm trying to fix-up a late 70s 5.7 GM. Casting numbers show it as "78"
It came out of a 1972 24ft Starfire hardtop with the original OMC electric shift.
