Before you buy the boat under discussion, you need to be aware of several possible problems:
- The boat has a notched transom, so it needs a short-shaft or 15-inch-shaft-height engine. It is unclear from the three photographs if the engine on the transom is a short-shaft engine. Short shaft modern engines are rather limited to just a few models. If the engine is not a short shaft, the boat won't run properly;
- Tiller steering with a 25-HP engine can be a bit tiresome. Usually a 13-footer with 25-HP would be a SPORT model, with a console, remote steering and remote engine shift and throttle controls. Yamaha does have some special tiller steering models that have a shift lever on the extended tiller. From the photographs it is hard to see if this engine has that feature.
- A modern 25-HP engine will be heavier than a c.1972 two-stroke-power-cycle engine, and with the tiller steering the helmsman will be sitting in the stern; both will create additional weight in the stern and tend to make the hull very light in the bow.
- You need to realize that a boat made in 1972 is about to be 54-years-old in a month or so. Old boats can be in good shape, but because of the "restored" nature of this boat there is no way to know what its condition was before the restoration. A glossy finish on the hull and woodwork could be hiding some repair work.
The most valuable part of this boat-engine-trailer combination is the engine. That is fine, as long as the engine is suitable, that is, as long as it is a short shaft model. That is the first element to check out.
The restoration certainly added value to the hull. But as you note, there a probably a lot of old 13-footers in your area, maybe not as shiny because they have just been well-cared-for since new, and have had no damage.
This 13-footer is a STANDARD model, the least expensive, and perhaps the least desirable. There has been a lot of inflation in the price of used boats in the last five years, but much of that was generated by the COVID lockdown of the country. Used boat prices are not as strong as they were in 2022 when KOVAR bought a used boat.
Also, the boat offered by KOVAR as a comparable at $5,000 is not really comparable. That boat is 16-years newer, has a 20-inch-transom, is a SPORT model, and has an appropriate 30-HP original engine with remote steering and throttle. All of those elements are significant upgrades from the 1972 STANDARD 13 that has been "restored" and re-powered.
The problem with buying an old boat with a very new engine is the seller probably put a lot of money into the engine. The only effective way to get value out of a buying a new engine for an old boat--and in this case a very old boat--is to keep the boat for 20-years and enjoy the new engine. Trying to sell a boat with a very new engine just put on the transom will generally result in the seller losing money on the engine purchase. Of course, the seller will try to avoid that, but he may not be able to hold out for the buyer who will repay him for the full cost of a new engine.
