Sander (What Kind) (Something affordable)
Sand Paper (What grit/s and how much of each)
Respirator? (What kind)
The prop was loose and sliding fore to aft. Wobbly. The lift master cleaned out the hub. Nut looked in place. Prop is a two blade aluminum
style. What should I be looking for?
Found a 8 to 12 inch (crack) on the port side forward portion of the keel hull
joint. The lift master stated this looked like common flex of the keel and didn't expect a major problem. (fair it out and paint
is what he suggested) Will look more closely as the bottom gets cleaned up. Comments
Thanks in advance for any guidance / suggestions
Hi, there, 3/4 Time,
For a start, get some gloves; get a 1-1/2" and a 4" putty knife type scraper (straight blade).
After the bottom is scraped, wet sand it with ~80 grit wet-or-dry, and wash it. It's a lot of work, and hopefully the bottom doesn't need scraping (1-1/2" carbide scraper and many hours careful work). This should give you a nice bottom. Now you need a roller, roller covers, and roller pan; you'll want disposable bristle brushes
for cutting in where you need to. Masking tape, good quality (it may be on longer than planned, plus the cheap
stuff allows the paint to creep up under the tape onto the topsides).
At this point, you prime it with a primer compatible to the paint you have selected.
We usually carry our stuff in buckets, but we have 'em 'cause we live aboard.
You'll want paper towels, thinner appropriate to your paint, you'll probably want a drill motor
to drive the paint stirrer, does a better job than hand mixing with a stick. Best way we have found to mask is to start at the bow and work aft, keeping your eye on the line you're creating. If you just push it on, looking straight at it, you get "wows" in the line.
#2. I don't understand what you meant by "the lift master cleaned out the hub". What hub? aren't the blades attached to it? On one hand, it sounds like a set screw isn't stopping the prop sliding. How is the prop attached to the "hub"? Our hub is a pressed fit on the prop shaft, no set screw, so I'm not sure what yours' screw is supposed to do.
#3. I'm not game
to suggest how you deal with the crack at the keel to hull joint. Is it just a few hairline gelcoat
cracks? Is it a big gap that has previously been filled with sealant
? What is the nature of the keel attachment? Keel bolts
loose? After the bottom's clean, and the gap cleaned out, you might ask someone at the yard the best way to proceed and see if that makes sense.
I know this is only a little of what you're needing to know, but it's a beginning, and others will chime in and offer more.
