My boat is pitching a fit... I was running her the other day up the river when out of no where she started to break down ,, She will start right up and run ,,,but if you give her gas and thing above 1and half grand she breaks down and wont rev up... Ive changed out points condencer ..rotor ,,,plugs,, rebuild carb ..i just changed cap last year ,,,and looking in side there is no arcking at all.. never had it do it before ,,i own a 1989 VIP vindcater 302 v8 2 barl... it wont tak any rev and just breaks down any ifo ??????
