Looks great Wayne. What are those pulleys? I didn't see them on your list.

Thanks Joe,

Pulley's I found at Murray's,..... CHM I think, anyway, if you look at the installed picture, you'll see I didn't use the crank pulley. I didn't like the way it was aligned to the balancer. The stock pulley has a little lip that rides on the inside of the bolt hole for the balancer, holding it dead center. Also, the after market pulley had a little step machined into the back that threw my belt alignment off by about 1/8 of an inch. So, I enameled the stock pulley, and stripped all paint off the plate, and installed it.

I'd still like to clean up some stuff (I guess all the remaining stock stuff), but that will have to wait. The next project is a new interior for the boat, but even that will have to wait until next winter.

Not yet,...... :bawling:

But, I'm hoping to take THIS Friday off too,...... and will definately be out Saturday (weather permitting). But I'd really like to run it by myself Friday to get some good RPM and speed readings off of the prop before I load it down with my tribe!!
