Gelcoat Crazing

Boat slaves never sleep. We're either working on the boat, busy making money to keep the boat running, researching about boat stuff or lying in bed thinking about the damned tub. The fact that non-boat owners can live a fulfilling life is a mystery to me.

Take note Corbin 39 owners, don't paint your overly thick gelcoat in a dark dull color. It will get really hot in the sun resulting in gelcoat crazing or cracking.

I already knew the paint would not fill the cracks, but I have no time to fix it properly. However, the new lighter glossy paint reflects sunlight and hardly warms up at all.
Up close it looks as though it was painted with a broom. From a distance it looks great, even the boat looks clean, which it isn't.

Not having any translations lined up for Monday, I drove to Nazaré early in the morning in an attempt to get Jakatar ready for the splash.

Had to cut new bolts to size for the dripless stuffing box collar. A tidy work environment is not my forte.
I aligned the shaft to the engine and re-positioned the stuffing box collar per instructions. Lacking spacers to align the shaft, I invented a new and perhaps better way.
Here are the instructions:

  • attach the propeller shaft flange to the transmission flange with two bolts (one at the top, one at the bottom); 
  • Then hand-tightened them just enough to keep the flanges touching;
  • Next, rotate the shaft 1/4 turn and check if either bolt is slightly loose, and repeat for all positions.
In my case, the top bolt was a touch loose when it reached the bottom position. To correct this, I raised the back of the engine a wee bit and got it almost perfect...almost so I'll give it another go when I'm in the water again.

I scheduled to launch on Thursday morning, after I clean up the unbelievable mess in the boat and cockpit.

How much is this boat worth? Looks bankrupt to other words, negative worth.


  1. I couldn't relate/agree more with your opening statement. And your workshop seems fine to me. You also have a vise (something on my list even before I bought me boat).
    Good alinement tip. Do you have a plastic(?) flange between the shaft flanges to take up any miss-alinements?
    How's the sun over there. Here it's impossible to do anything between noon and 6, so I just "look" at my mess.
    Happy slashing, my friend

    1. Hope you realize that it's the shop in the boat, not my garage. Got to have a vise and a place to fasten it, which implies drilling two holes on a surfasse with access from the underside.
      No I don't have a plastic flange thing (also forget the name right now), but my dripless stuffing box tolerates a bit of misalignment.
      It's hot here too, for now.

  2. This is my first time i visit here. I found so many interesting stuff in your blog especially its discussion. From the tons of comments on your articles, I guess I am not the only one having all the enjoyment here! keep up the good work Johnson outboard seal kit

  3. Interesting topic for a blog. I have been searching the Internet for fun and came upon your website. Fabulous post. Thanks a ton for sharing your knowledge! It is great to see that some people still put in an effort into managing their websites. I'll be sure to check back again real soon. Aftermarket Mercury outboard parts
