Question about Yamaha 12V Air Pump
The engine seems to be lockup and not sure if engine or pump is the problem. Engine had teaspoon of oil in each cylinder when it was stored. Had all the spark plugs out and sill can not turn engine over. Tryed to turn the output shaft with no avail. Battery is good and starter seems to strike the fllywheel hard. Not sure how to sperate the engine form the pump to see which is the problem. Can not understand why the engine ran fine when put away and now it will not turn over.
You can take the whole pump *** out from the back of the ski you will see the main bolts at 2,5,8 and 11 oclock there are two sets of them one on the nozzle and a set on the pump take all of the steering cable bolts out first and the reverse cable as well once you get the nozzle off the pump assembly will come out complete that way u can find out if it is a impellar bearing seized that will lock your whole motor if you need a break down go to riva yamaha and go to origanal parts finde4r and pick your ski it will help
