I bought an Evinrude 2000 FICHT E115FPLSS with a jet prop on a river boat last fall. Serial number G04752072
The boat ran and started great into the winter. After setting up for two months it could only be started with carburetor cleaner sprayed in to intake. I changed the gas out and now it will start sometime after cranking forever, and sometimes till takes a boost of carburetor start into the air intake. Once it starts it runs ok except for an occasional miss. What can I do? Is it ok to try sea foam? Should I change the plugs? Also, I am using evinrude ED-50 synthetic oil. Would XD-100 be better? And lastly, where can I get an owners manual?
