Has been a great motor. Spring cleaning includes gear lube, water pump, prop service, new motor end fuel lines, new remote tank, new boat end fuel lines (w/ water separator), fuel filter, plugs, carb kit (for both), carb disassemble, soak, and compressed air cleaning, and new fuel pump kit. No issues last season. Spark test good, compression good.
Test drive results.........starts first pull, idles like a kitten, smooth all day long UNTIL 75% plus on throttle and it surges as though it has a fuel restriction. Priming hose ball has no impact when it acts up. It does not cut off. The only issue seems to be WOT (75% + on the throttle). My guess is to tear the carbs back down and redo.........what say those with way more problem solving skills than me? Thanks for any advice.
