A 1983 electoral redistribution turned Fisher into a marginal seat, cutting Evans' majority in half. Most of the strongly Liberal areas of the old Fisher were transferred to the safe Liberal seat of Davenport, held by fellow Liberal Dean Brown. The ensuing preselection contest turned into a factional battle; Evans was from the conservative wing of the Liberal Party while Brown was from the moderate wing. Evans lost preselection for the the 1985 election to Brown, but stood as an Independent Liberal and defeated him.
Evans nevertheless maintained his Liberal Party membership, because at that time the Liberals did not have a policy of expelling members who opposed endorsed candidates. He rejoined the Liberal partyroom shortly after the election, and stood in the 1989 election as the endorsed Liberal candidate for Davenport. He retired at the 1993 election and was succeeded by his son Iain.
