The motor itself will run forever. I had a 61 Evinrude 10 hp that has been run all summer EVERY summer since it was built. It belonged to my great uncle, then my Uncle, then Dad, then me, now my nephew has it. I have wished every summer that it had an hour meter on it because I would love to see.
The electric shift will cause you headaches. It will likely fail every two years like clockwork leaving you with only neutral and reverse. IIRC, you can convert to cable shifting with a little work. No one else offered electric shift, and OMC only offered it for about 6 years before they scrapped the idea.
The hull itself would only bring money to an oddly passionate enthusiast. Don't overpay. Forgive the blunt honesty moment here: Hulls like that do a great job of floating, but they don't excel at anything. They won't be overly comfortable in chop, they won't keep you dry in the spray, and they won't be fast. They are perfect for a beginner because they have flash and style and "lake cred" but a more experienced boater wouldn't pay more than $500-1000 for it because they know they can buy something more modern that DOES excel for $3000.
Those old stylin' 50s and 60s boats are like a Triumph Spitfire.... all the style, but tall skinny tires, underpowered by today's standards, and not quiet and comfy. Most buyers wouldn't buy one as a daily driver choice when they could have a 2010 Corolla that is quieter, more reliable, and would beat the pants off a Spitfire on a track.... and cost about the same money.
Having said that, I would LOVE to own a Spitfire because I understand the passion for a design or a certain aesthetic.
A few years ago, I sold a 58 Sea King runabout with that 10hp evinrude for $100 on the family discount to my Nephew, but in all seriousness it probably would have brought $500 on the open market around here, and I think the trailer would have been half of the value.
That is a long way of saying... yes, I think that is a fine boat to get your feet wet. Just don't fall for "classic boat worth millions." Old boats don't hold their value like a classic car. If I were in the market for a boat like that, I wouldn't pay more than $1000 and only if both the boat and trailer had a good title, and only if I did a complete inspection on the core for rot. That comes with the caveat that all boat markets are different and I don't live in a marine-heavy area.
For the sake of comparison, my current boat is a 91 Ebbtide 18' I/O. It sits on a brilliant, top-of-the-line 2008 Load Rite aluminum trailer with LED lights and a torsion axle. I snagged it for $3500 about 5 years ago and it always starts, runs, and it's comfy as heck while doing 35 mph with 4 people in it. Boats like that around here are common. A big, heavy I/O might not be your cup of tea, I just mention that for comparison.
