I have a 1987 rinker and left a half tank of gas in it through winter. Took the boat out beginning of season it was boggy and back firing. Wouldn’t go over 3000 rpm under load.
from there I put a rebuilt carb on, new plugs, distributor cap and rotor (timed 8 degree BTDC) fuel water separator, fuel pump and changed my oils, also put a stainless prop (same pitch) and hyrdafoil.
after all this work I put it back in water and still back firing and loading up and won’t go over 3000 rpm under load, in neutral I can rev it clear to 6000 rpm. also seems cold blooded and will only stay idling when up to temp. Ran a whole tank of new gas with sea foam and same issues.
any help is appreciated!
