Re: Nissan 9.8 priming problem
Sounds like a fuel leak under the cowl.
When the fuel spills near the engine the vapor causes the intake to run rich making starting an issue.
Lift the cowl and the fresh air helps the engine start.
Check for a leak near a hose fitting under the cowl.
Nylon ties are not hose clamps, Tohatsu have a similar issue on their smaller outboards.
