Hi, Can someone tell me the oil to gas ratio for a rotax 787
seadoo challenger boat? My oil injection is no connected.
I think the 4 0z. to one is too high.
Thanks in advance.
:)
 
Gas Ratio

Linda, the gas ratio on the 787 is the standard outboard mix. 50:1....or about 13 oz. to 5 gallons of gas.
You need to remove the oil pump and take out the shaft. Then block off the oil injector lines at the carbs.
You'll need to leave your oil tank in because it also supplies oil to the rotary valve shaft chamber.
Hope this is of some help to you.
