The manual of Volvo Penta
D2-75F recommends to start a cold engine
in half throttle.
I used to start it always in off position. Now it starts only in half throttle. Or it takes few attempts if I try to start it in 'off' position.
It's only 20C outside so the engine
is not really cold.
like seems to be OK. Pump
is hard to press.
On my previous boat
I had a Yanmar
and never knew that it it should be started in half throttle. It was fine even in 5C outside.
So my question is could it be a sign that something is about to break?
