Yep,
Diesels are in the last few years of the 25+. The last year was 1983. Don't know when the diesels started being available in the 25+. I've seen some of those gas OMC outboard-powerhead/saildrives in some of the earlier 25+.
The 1982-3 E25+ has a lot of teak in the interior, close to the amount in the E26.
In 1984, the E26 (same hull as E25+) came out with the Yanmar 1GM, 7hp diesel, then got a 10hp. The E26 boats with serial numbers 200-299, between 1984 and 1987 have the nicest teak interior of all the small Ericsons (E27, E25+, E26).
