engine, 5.8l 351 ford
hull, four winns sundowner 225
outdrive, cobra
gas, mid-grade
prop, 15x15, 15x17
max rpm 4k-4,400
my problem,
at wot or 4k+ rpm i can only do about 200 yards and then the rpm drops slowly about 500, then starts to backfire. i then have to return thottle to idle and wait a second then take off again. only happens at 4k+ rpm,.
i put 15 miles on today doing 3800-3900rpm never had an issue temp was running at 175. heading back to the docks i put thottle down 4,300 rpm and then it happend again. the temp was about 180 when i put the thottle back to idle.
did a recent tune up plugs, wires, dist. cap, rotor, set timing, reset ESA was stalling on me, lower unit oil, impellor.
i read a post a while back with an rpm limiter or something on a 454 king cobra i think, obviously not the same engine or outdrive. i just dont know where to start looking. other wise is there an idiot switch for the temp incase its because it shoots up to 180?
