How much does a 2000 johnson 8hp 2 stroke weigh

SOURCE: johnson 4 stroke 115 hp will not start. fuel

Sounds like and injector problem to me. If it was a 2 stroke I'd tell you to pull the carbs and clean them ,but EFI is a whole different story. Most certaintly a fuel problem, most likely injector related, you'll most likely need to go see a marine mechanic with the proper equipment to analyze, rather than start replacing parts you may not need.

It's two-stroke. You need to mix oil with your gasoline to provide adequate lubrication.

if you haven't fixed this already, take the pastic water pick up covers off there are two joiner nuts in there undo them, there is a plastic cone on each end take them off and it will slip through. I own the same model and year outboard.

SOURCE: water pump not working on

sounds like you need a new water pump impeller.
to access the impeller the bottom of the motor needs to be unbolted and the impeller is fitted to the shaft, it is keyed so it only goes on one way. ( impeller kits will come with new gaskets,grease.O-rings and a new key ). re-bolt the lower unit and test.
