    Posted: July-20-2009 at 9:17pm
After running the boat for 3 seasons without checking the alignment, I decided it was time. I removed the bolts and determined the plates to be stuck, perhaps rusted, together. I spun the shaft from inside the boat. The small amount of resistence was symetrical and consistent. I tapped a small screwdriver into the seam and gently tapped the plates with a hammer, but I could not get the plates to separate. I did not want to do any damage trying to force them apart. Nothing suggested that the shaft was out of alignment. I never had a chance to use my gap wrench. Am I good to assume that my boat is in aligment?

Mine were rusted together also, I used a chisel and hammer to get them apart- then used a file to clean up the chisel marks and a drimel with wire brush to remove the rust, no harm done- my alignment was way off, now my boat runs alot smoother.

You know where that word leads.

From what I've seen with my own boats and a few others I've turned a wrench on, I'd say your odds of having good alignment are less than 50/50. I've even seen a couple that were visually out! Split the coupler and take a look. Remember to start at the strut if you need to reset it.

Eric, thanks for keeping us 'straight'.    

I had no idea how important alignment was with my '79. Part of why I sold it was it didn't run smoothly...bet I could have fixed it.

I need to look at mine again, I did it on the trailer over the winter after replacing the bushing but ive still got a growl at the lake. Vacation next week at the lake I may take my tools up and straighten it out...

75 - My alignment changed by .003 or .004 between checking it on the trailer vs. floating.     pretty sure my stringers are OK, so apparently the hull flexes that much.

Is a hammer and chisel the way to separate the plates?

Hammer & chisel is what these guys have mentioned before, but I have never had to resort to that level of force. Have you tried soaking it in PB Blaster or similar?

I once had a brake rotor that was rusted on - tried everything, including a puller, to remove it. The shop guy hit it for 2 seconds with an air hammer & it fell off. Not recommending this for your boat, but I wonder if it would work. Eric?.

This comes up over and over. I didn't ever have to break mine loose, but I do think it's fair to say that it will need adjustment if it's rusted shut.

snob, air hammer and torches are my favorites. my favorite use for the air hammer is u-joints, knocks them right out....once in a while to knock off a prop (with pressure applied), knocking out bearings, it has many uses

Hello,

I used a metal putty knife to get mine apart.

I hope this helps,

Donald
