The recent inception of "weird" displacement engines that are being marinized may be a different topic to debate as the inventory isn't quite as plentiful as your basic 350 c.i. long block that has been used for ages.
The point being that the idea of refurbishing an old boat, going forward with the newer electronics, the engine may be the least of your worries. Where you have a boat that is pre-all-so-much -electronics I think an engine replacement is a reasonable consideration.
With the newer boats that have almost all the functions controlled through a touchscreen, all that has to happen is for the OEM of those electronics to decide to no longer manufacture a part. So what I'm saying it is going to get interesting in the future on keeping such a boat running for a long life time. Consider that features such as cruise control (generic name), gauges (speed, temp, rpm), ballast systems, etc are being controlled through a central module now days.
