I have a '75 170. I believe these are very similar boats. Here are some thoughts and remember, they are worth exactly what you paid! (meaning, they might be worthless)
Sounds like our hulls (and personal preferences) are similar. I'm a purist, and I would love to Awlgrip my boat. But it's incredibly expensive. I keep reminding myself that if I was going to spend that kind of money on paint, a new 4-stroke, etc, I might as well find an old 22-2 and have a bigger, refurbished boat that makes sense to have $25,000+ invested. Although I just bought a new aluminum trailer...that feels pretty good. (Peace of mind, easy loading, classy, etc) But can I justify it? Hmmmm....ask my bride.
Anyway, regarding:
* Anchor hatch: I believe they were teak originally. If you reach inside, you'll find there is some structure around the oddly shaped opening...but it shouldn't be hard to reproduce a teak one.
* Aquasport raised logo: I know it's expensive but if an "original" hard plastic logo is important to you, the only way might be to find a graphics/signage company and get them to cut one out. They're beveled so get ready for $$$. Or, match one in vinyl. Not long ago, there was someone on this site who could produce them...I think there's a 'string' about it. Take a look at Calusa Wind...his logo is vinyl (not original) and looks great...along with the every other detail of that boat.
* Floor. They are very 'paintable' with epoxy, although you will find that it's a LOT of work, moving the console, removing hatches, etc. And then you're gonna want to paint the hull - it's a slippery slope! So I cleaned my floor with a good color-restoring fiberglas cleaner, then rubbed Penetrol on it. After it's dry, the Penetrol isn't slippery and it looks pretty good. I did the same thing to the hull inside and out (cleaning/waxing/buffing...not Penetrol) Scrubbed the rub-rail with BonAmi...it improved. Oxalic acid for the brown water-stain I get after a few days in the water.
* filling holes & chips: I experimented with adding off-white color to gel coat, until I found a blend that was very close to the hull color. This is easier said than done...I had a hard time with the underside of the hull. Here in Houston I know some excellent fiberglas guys - it's a lot more expensive but their work is just so much better than my own.
* Hairline cracks...for the most part, I don't worry about them. Awlgrip will cover all of that but again, only you can decide if it's worth the money. For me, new wiring is my next effort. C
