[2] The Peruvian Corporation carried out two important remodellings to the original ship: between 1927 and 1929 it elevated the propeller, taking care not to spoil its gauge; and in 1956 it changed the old engine for a Paxman Ricardo of English manufacture (1948) with 12 cylinders in V, with a power of 410 HP allowing a speed of 10 knots.

Even though peace had already been signed with the Treaty of Ancón between Peru and Chile to end the War of the Pacific on October 20, 1883, Rear Admiral Lizardo Montero and General César Canevaro resisted in Arequipa.

Upon reaching Puno, on the shore of Titicaca, they boarded with their men the steam gunboats Yavarí and Yapurá, to sail towards the lake port of Chililaya, in Bolivia, where General Narciso Campero was waiting for them with two Bolivian battalions to resume hostilities against Chile.

However, a Chilean division arrived in Puno on November 4, 1883 and its local authorities immediately handed over the place, declaring themselves in favor of peace and the government of Miguel Iglesias.

[2] In 1976 they were transferred back the Peruvian Navy, and renamed as BAP Puno, the name of the locality of its Base port, and assigning it to passenger and cargo transportation tasks and as a Coast Guard of lake naval force.
