Why is my Yanmar 3YM30 Engine having trouble starting?
If you're having trouble starting your Yanmar Engine, it could be due to a few reasons. First, make sure fuel oil is being injected by priming well. Also, check if the pinion or ring gears do not mesh, and if so, tighten them. Finally, ensure there is sufficient fuel oil in the tank by adding fuel.
Why does my Yanmar 3YM30 have abnormal exhaust color?
Abnormal exhaust color in a Yanmar Engine can indicate several issues. Black smoke may mean the load has increased or the propeller matching is improper, or the intake silencer (air cleaner) is dirty (clean the element). It may also indicate improper fuel (replace with recommended fuel) or faulty spraying of the fuel injector, or incorrect intake/exhaust valve clearance. For increased load, improper propeller matching, faulty fuel injector spraying, or incorrect valve clearance, consult an authorized Yanmar Marine dealer or distributor.
