Anyone have the cutlass bearing size for a 1989 32' SDFB?

1.25" shaft
1:1 Velvet Drives

Pulling the boat next month for bottom paint. Plan to replace the bearings while it's out of the water.

Thanks!

In case others want to know, the cutlass bearing dimensions are 2" x 5" X 1.25". The Johnson / Duramax bearing name is a "Dotty".

i have a 1975 32' sedan with flybridge and 318 motors would this be the bearing i need?

I may be mistaken, but I thought some older 318 powered M's used 1" shafts.

looks like some measuring is about to happen would like to install new ones before launch day

Mine are 1 inch shafts ( part named BETTY ) easy way to measure is grab a 1 inch open end wrench and see if it fits the shaft. If you don't have a 1 inch, then use a Crescent wrench and adjust it to be snug. Then measure the wrench.

Thanks Wil give tat way a try.

It's a hell of a job. In the middle of it right now. Beware of set screws at the prop shaft coupler that like to break off, as well as the ones that are in the strut. Not sure you can get to it without pulling rudders as well. Also boat needs to be positioned so you can get shafts all the way out without running into the ground. Big Job!

Mine have some play in it just star board side .the other is tight.

The shafts WILL clear the rudders.

Don't sweat those setscrews. Just re-drill and tap for new ones--doesn't matter where.

I used a long Sawzall blade to get mine out.

Be sure the new bushing will slip into place, without binding, before ramming it in there. If it sticks halfway in you're in trouble! I used drum sanders to clean up the strut, and a slow-curing epoxy to hold the new bearing in place (plus setscrews). The bearing slide easily, 'lubricated' by the epoxy.

I used a long threaded rod to pull the new bushing into the strut.
