I am by no means mechanically inclined. I change wheels and tires on my cars but always have a shop change the oil, do brakes and rotors, etc. My tool collection is bleak and my experience with working on anything other than bicycles is minimal. But, this forum exists.
In the past year on my Epic I have learned to winterize it (despite both block drains being completely stripped), replaced the impeller, taken apart the entire seawater intake system to chase down issues, changed the oil, changed spark plugs, replaced the serpentine belt, replaced the battery, and most recently replaced the rubber exhaust hoses.
I am now in the process of replacing all of the gauges with analog gauges and re-wiring the dash and stereo. I also found some cracks in the fiberglass mufflers and am going to attempt to repair them, working with fiberglass for the first time.
With all of that being said, this was all deferred maintenance from the prior owner. I got a pretty good deal on the boat, and despite missing some time on the water I'm learning A TON by just digging into the boat and figuring things out. I'm relatively confident that I have a good understanding of how everything works. I honestly wouldn't trade this entire experience for a more expensive boat that was turn-key ready.
Its all right in front of you when you take off the cover and floorboards. None of this is insanely complicated stuff. Somebody might have to convince me that trying to do the timing belt and water pump might be a bit ambitious, the DIY write-ups make me think I can tackle it.
